The neuroscience of Notion in enjoyable quotes…


perceptionTVshowposterWithin the pursuits of continuous to be a magpie that picks up shiny accessible cognitive science, and packages it in tasty bites so that you can add to your ‘considering abilities’ – I’ve transcribed quite a lot of ‘quotes’ by the character of Dr. Daniel Pierce, a crime-solving genius neuroscientist within the TV present Notion.

The adviser for the present, (and presumably the supply of the science within the script, and subsequently these quotes), is rock-star neuroscientist and creator David Eagleman – who stated of the character:

David Eagleman at Ted. Click on for information on his function with Notion.

“Pierce has an intimate information of human conduct and a masterful understanding of the best way the thoughts works. He additionally has an uncanny skill to see patterns and look previous individuals’s aware feelings to see what lies beneath.”

I really like the opening of every present, the place Daniel is giving a lecture to the scholars in his fictional Ivy League school, and he challenges them with suppose statements concerning the thoughts/mind. Have a learn by means of, and take what you need from it, there’s so much there. And revel in!



Notion lecture quotes season one:


We’re not allowed do overs? You don’t like what occurred ? Do over! Each second we expertise leaves a everlasting imprint on our brains – shaping how we understand issues and other people sooner or later. Continuously reminding us to watch out: who can we belief? When are we protected? What are we able to?


There are advantages to a cautious lifestyle – it helps us to keep away from discomfort, unhappiness, illness, hazard… however there’s one hazard it could actually’t assist us with, that’s the hazard that our biases forestall us from seeing issues as they are surely.


What’s actuality? Actuality is a figment of your creativeness. Who hasn’t woken up breathless from a nightmare? Neuro-chemical impulses that fireside after we’re dreaming, visualising, imagining, are indistinguishable from these after we truly expertise the occasion. How can we all know what’s actual and what isn’t?


What’s ‘regular’? Are you unhappy? Or are you affected by a neuro-chemical imbalance? How do the brains in ‘regular individuals’ reply to sure stimuli?


So I went fishing, caught a HUGE bass – THIS BIG! Alright, so, you’d know I used to be mendacity how? If I used to be a greater liar, I’d have an enormous benefit, a greater job, extra buddies – research present! What goes on within the mind whenever you’re mendacity? Your prefrontal cortex would mild up like a christmas tree, we use our brains after we lie… Can the mind ever deceive itself? The self is a group of a number of distinct neural networks, all working on this blob of mind jelly… Which you is the true you? Do genetics and surroundings cease you being ‘you’? Can you modify who you’re?


Which comes first, yesterday or tomorrow? What we consider as previous current and future is a narrative stitched collectively in our basal ganglia, a ‘assemble’….


All we actually have is the current second, the dear and irreplaceable ‘proper this second’, that’s by no means to get replaced once more in all of historical past. Savor this whilst you can.


What’s a conscience? Can we find it in an MRI? Individuals with injury to the prefrontal cortex are extra keen to sacrifice a human life, so long as they understand it’s for some larger good… What about those that haven’t any bother with heartless cruelty? Is empathy an aberration? The excellent news is that there’s an evolutionary benefit to kindness and co-operation, however on some stage we’re all lone hunters, and it could actually really feel harmful to indicate kindness to different members of the tribe…


Does freewill exist? Do I exert aware management over my actions? Or was I compelled to do it by some unseen neural course of? Science suggests free will is an phantasm, if that’s true are ALL our selections made for us?


Is there one thing improper with me? Why don’t I appear like, act like, really feel like, all people else? No two brains are precisely alike, so being completely different, being distinctive, is undeniably a basic attribute of being human.


How dangerous would you like it? Cash? Success? Ambition drives us all. What William James referred to as ‘the worship of the Bitch goddess success’. Freud would have us consider that every one drive stemmed from the libido – however now we all know that success is neurologically decided by ones skill to remain targeted on a process; and persistence is a operate of an energetic limbic system.


Our ambitions and our desires give us a glimpse of an exquisite sometime, and assist us to get although a troublesome right now – however it could actually blind, and eat us, and lead us to empty hedonism. Irrespective of how a lot we’re fueled by it, it isn’t carved in stone – desires change, and even when we don’t get to climb mountains, there’s nonetheless an opportunity we are able to transfer them. You may’t at all times get what you need, however when you strive typically, you may get what you want.


What are you afraid of? Dying in a airplane crash? Catching a illness? What it is best to actually be afraid of is failing this class! [laughs] Worry can override rational thought – earlier than the neocortex may even course of a menace, the amygdala kicks in, and now you’re in combat or flight mode. The identical neurological programming can even spook us, inflicting us to behave irrationally, when in actuality there’s nothing to fret about. Can we override our most primal instincts, situation ourselves to not react out of worry?


Generally the billions of neurons firing in our brains concoct essentially the most elaborate situations, a ‘dream job’ and many others. – however fantasies can flip darkish, we begin to consider there’s a monster below the mattress, or that evil forces are aligned towards us. All these fantasies, good and dangerous, stem from an evolutionary crucial; our brains are exploring potential outcomes that may assist us attain our objectives or keep away from hazard. But when we permit fantasy to overhaul our considering, we may miss the fact that’s proper in entrance of us. And typically, actuality shouldn’t be so dangerous.



Season 2:


[college movie day…] I confirmed these clips to pose the elemental query – what’s an irregular mind? How does having one have an effect on conduct? …. Some are treatable with surgical procedure or drugs, however we’re caught with the three kilos of cauliflower we’re born with. Can we alter? Is it malleable? It has the flexibility to vary and develop all through our life. In essence, our experiences rewire us, make us do and suppose issues beforehand unthinkable, provoke us into forming new ideas and concepts, educating us classes to keep away from the errors of our previous. Our mind is in a relentless state of flux. Nothing in life is everlasting.


Lets speak about love. How does love rewire the mind? After we meet somebody new and thrilling they invade our synapses like a virus, triggering neuro-chemicals that feed into attraction, arousal, obsession… We get distracted, we take into consideration them on a regular basis… However we’re not simply fascinated about them, we’re constructing an inner mannequin, a simulation that helps us to foretell how they suppose, or how they’ll really feel. Relationships get into bother when the simulation meets actuality. Will we ever actually fall in love with one other particular person? Or simply with our thought of who they’re?


Why can we trouble with relationships? We’re hardwired to crave intimate connections – we lengthy for love, despite the fact that some finish in heartache, leaving our delicate psyches shattered. Why can we even trouble enjoying these odds? As a result of we solely need to get it proper as soon as, and when it’s proper we all know it.


Why can we see a person within the moon? Jesus in toast? The human thoughts has developed to see patterns and that means in nearly every thing, referred to as paradolia.


What if I advised all of you that you simply’re partially blind? That you just suppose you’ll be able to see every thing, however actually you’re lacking one thing? It’s true. Each time we open our eyes, mild shines on our retina, nerve cells interpret and transmit to the mind, however a small space, a blind spot on the retina, can’t do that. How come we by no means discover the black space in our visual field? The rationale you by no means discover is that your mind is nice at guessing what ought to be there, and filling within the clean. Generally we all know what we wish to see, and our neocortex turns the expectation right into a digital actuality. A number of the world we see is basically simply an phantasm. How can we uncover our blind spots? How can we ever totally see the reality that’s proper in entrance of our eyes? Merely open your minds…. The eyes see solely, however the thoughts is keen to understand it.


What’s your deepest darkest secret? The one you’ve by no means advised a soul? Did you betray a buddies confidence? Shoplift? Sleep with somebody you shouldn’t? Bought a secret? Proper now there’s a battle happening in your mind, your cingulate cortex needs to inform the reality, however the orbital prefrontal cortex is simulating how dangerous it is going to be… If the prefrontal wins, your stress stage goes up – if the cingulate wins, it drops. So if it’s biologically more healthy to admit, what’s it about human nature that make us combat so onerous hold them hidden? Freud stated no mortal can hold a secret: ‘if his lips are silent he chatters along with his fingertips, betrayal oozes out of each pore’. He might need been on to one thing. Though we could also be determined to maintain our secrets and techniques, the tougher we attempt to bury them, the extra they rise to the floor. We’re neurologically compelled to admit. That’s an excellent factor, confession is nice for the physique and mind, possibly even the soul, when you consider in that form of factor.


Check out the particular person subsequent to you. What do you see? A rival? A lover? Would it not shock you to study that’s it’s largely a fantasy? We get to know individuals by taking just a few small clues, and processing them although a neural filter laden with our personal private biases – we depend on our thoughts to fill within the blanks of their id. However how they actually are, their essence, that’s in their brains, not ours. The fact is, (till the following dropout invents a option to plug in to others brains), we are able to by no means actually know who they’re. All we are able to do is arm ourselves with what we all know to be true: our emotions. Love and longing, happiness, worry, friendship; these are the brains steering system. If we are able to belief them, they assist us discover what we’re searching for.


[Chops a melon… as if to remove a diseased part of the brain…] Capabilities as soon as managed by the left hemisphere, the language centre, can ultimately develop in the appropriate hemisphere. To be totally human solely takes half a mind. Do now we have extra mind energy than we’d like? Or huge quantities of unrealised potential?


Why can we always try for enchancment? A lot of our ambition is pushed by the prefrontal cortex, it’s why we’re right here, and never within the jungle consuming bananas. Day-after-day we hear of latest technological developments; upgraded telephones, computer systems, new medical methods… science appears to have limitless potential. Many advances do make our lives higher, however in our striving we are able to lose one thing essential; accepting what’s already good about ourselves. Mozart, 200 years previous, doesn’t require an improve… is ideal simply the best way it’s.


We wish to consider that the mind is all highly effective, that there’s nothing we are able to’t study or conquer – however regardless of it’s class and effectivity, there are some issues the ability of the thoughts can not do. Generally when confronted with an intractable drawback, it’s not the mind that may resolve it, it’s the center.


Life awaits: friendships, inspiring work, independence, your home on the earth… all exterior the door. Think about if that door was locked? You’re trapped, all people else resides round you. That’s what psychological sickness appears like.…. Surgical procedure can’t train us the right way to care for ourselves.. a protracted course of… begins with studying the right way to belief our personal minds once more. Neurologists are a loopy bunch who consider we’ll uncover cures, that there’s hope for all of us.


‘There are not any second acts in American lives’, stated F Scott Fitzgerald. However there may be for the mind! Devastated by damage, acquired savant syndrome, a highschool dropout, savagely attacked, wakes to turn out to be a gifted painter! If our brains can have a second act, why not our lives? Damaged relationships can heal, sins may be forgiven, wrongs may be righted. In our lives, as in our brains, all of us deserve a second probability. We simply need to be courageous sufficient to see it.


Albert Einstein had an enormous one. A prefrontal cortex! Extra mind tissue correlates to extra intelligence. The dimensions and organisation of his mind allowed him to realize greatness. Was he born with a particular mind? Or did it develop with hundreds of hours burning the midnight oil? Almost definitely a mix….


Did you ever marvel if any individual out there’s precisely such as you? A dopple-ganger? How does surroundings and genetics have an effect on us? (…. Boring – searching for a soul mate… want for a twin is an expression of our want to attach, as a result of on this huge and overwhelming universe solely {our relationships} with different individuals assist us to not really feel so alone)


A way of morality is rooted within the circuitry of our mind. How a lot are we born with? How a lot is formed from the environment? How a lot is realized from household? So many exterior explanation why we observe sure guidelines or conduct ourselves in sure methods… Is it doable some are born with a stronger ethical character than others? Some research present {that a} bigger orbital prefrontal cortex correlates to having extra buddies. What sort of buddies? Work? Web? Mates who put up together with your rubbish? Or a greatest good friend? The extra you nurture, the deeper it grows… until your good friend is household, during which case you’re caught with them, it doesn’t matter what.


There’s nothing worse than a liar. Why can we take exception to them? As a result of it feels awful. Actually. Disbelief will get processed by the limbic techniques cingulate cortex and the inside insulin, the identical a part of the mind that reviews ache and disgust. We lengthy for one thing to consider in. Our brains reward us emotionally after we consider, we really feel good, snug. We stability all of it by important considering, by questioning every thing, and at all times at all times being open to risk.


Again in caves, our survival typically relied on the flexibility to determine quick who was good friend or foe, it stored us alive. The amygdala served to make the snap judgments that stored us alive: combat or flight. It is perhaps primitive, but it surely doesn’t imply it’s dangerous. Generally combating for what we would like is the appropriate factor to do. Usually we’re combating worry of getting damage, of constructing errors. Generally it’s clever to get out of dodge, to get off on our personal…


Now and again we have to break with the previous, take a leap into uncharted territory.


Why do nails on a chalkboard sound so horrible? Neuro-acoustics. One idea is that we dislike sure frequencies as a result of they sound like monkeys, predators, or a child’s cries…



Season 3 – half one


Paris is like love or artwork or religion – it could actually’t be defined, solely felt. As a child after I first heard these phrases in a film, an important film with Gene Kelly – it was my introduction to this magical metropolis. Most individuals solely know Paris by means of artwork or poetry, and this will create sure idealised expectations that may turn out to be embedded in our neural networks. After all Paris isn’t at all times what we see within the films. Waiters don’t simply burst into music on the drop of a hat, regardless of how a lot I tip them. And, in some instances, some vacationers undergo a weird psychological response when their idealism of this metropolis collides with the true factor. They really feel disoriented, they undergo emotions of delusion and paranoia, some even expertise hallucinations. This excessive type of tradition shock is thought, appropriately, as Paris Syndrome. What does this form of phenomenon train us concerning the mind’s skill, or incapability, to adapt to the unusual and the unfamiliar…. [think about that]



‘You’ve gained weight’. ‘You look drained’. ‘What the hell is happening together with your hair?’. It doesn’t matter how effectively your day goes. All it takes is one little off hand remark to damage it, proper? That’s as a result of the mind is difficult wired to recollect the damaging interactions reasonably than the constructive ones. However current discovery means that the upper areas of the mind can truly modify how the decrease areas operate. That we are able to use our ‘intention’ and our ‘consideration’ in sustained focussed methods to beat the mind’s damaging bias. In order that it may be in our management to find out how dangerous experiences have an effect on us. In different phrases, until you’re clinically depressed, being sad might, the truth is, be a alternative.


‘Sticks and stones might break my bones, however phrases won’t ever damage me’. Or will they? The identical areas of the mind get activated after we expertise social rejection, betrayal by a cherished one, as after we spill scorching espresso on our arm. In different phrases emotional ache hurts the identical as bodily ache. Science has developed medication that may alleviate, and in some instances get rid of, our bodily ache. And in some instances those self same medication are proving useful in eliminating our emotional ache. So the prescription for a damaged coronary heart may truly be taking Tylenol and calling me within the morning [students laugh]. However is numbing our ache at all times an excellent factor? The extra we all know ache, in all it’s various flavours, the extra we are able to recognize the sensations and the emotions that we like. It’s the character of distinction. If we by no means felt bitterness or anger then we wouldn’t deeply recognize our happiness. And if we by no means knew worry, then we couldn’t admire our braveness. So possibly to extra totally benefit from the magnificence in our lives, we should first acknowledge and embrace our ache…


The mind shops recollections in several methods, brief time period recollections, the place you left your keys, the lady you picked up within the bar final night time, are managed by the hippocampus. However he hippocampus doesn’t hold them for lengthy. It kicks them out to the cortex the place they strengthen or weaken, relying on how typically you go to them. Each time you entry a reminiscence, neurons are activated and that reminiscence goes stronger. However ignore a reminiscence for too lengthy, and chances are you’ll lose it endlessly. The previous can come again to hang-out us – the sins of our youth, previous sickness and accidents can stick to us for a lifetime. Even for all it’s unbelievable energy, that tangled mass of neurons that you simply name your mind is a remarkably fragile organ. Take it out of it’s bone helmet, and it’s simply jello, weak to the slightest wound. A single concussion can have long run results that present up a long time later as main illnesses like Parkinsons. A number of too many nights of binge consuming; your mind may by no means be the identical. Does that imply that we should always stay in protecting cocoons? By no means exposing ourselves to potential damage, bodily or emotional? Or is the true artwork of residing to beat our wounds, make one of the best of our limitations, and embrace our presents?



[students turn over pages to start their exam] Feminine pupil asks: “I, eh, I believe there is perhaps a mistake, the solutions are stapled to the take a look at?” Appropriate! Earlier than miss goody two sneakers right here blew the whistle, the neurons in your ventromedial and dorselateral prefrontal cortices had been firing all cylinders, making a rush of adrenaline and dopamine not in contrast to a boxer within the ring. However the combat right here was between impulse and self management. It’s referred to as temptation. Now her cognitive management mechanisms stopped her from dishonest, however a few of you had been about to undergo with it. I do know you had been, proper [points at guy, who nods, and everybody laughs], your self management was hyped by the extra emotional and impulsive limbic system which needed the simple ‘A’. That’s dangerous, that’s dangerous as a result of after we train larger self management now we have larger success at work, stronger relationships, and higher psychological well being. So if it’s higher to withstand temptation, why can we at all times discover it really easy to provide in?


Should you consider within the man with the purple cape and the pitchfork the world is split up into good and evil. After all, developed thinkers like us know that life shouldn’t be so absolute. Or is it? FMRI scans of psychopaths reveal that their brains have refined variations. There’s much less exercise within the pre-frontal cortices, and decreased regional mind matter within the paralimbic techniques. In different phrases, they might be wired to do ‘evil’. It’s a scary thought, however equally superb is our capability to do good. The brains skill to create empathy, compassion, and connection. These items may give somebody the drive to stay a lifetime of sacrifice, or decide to somebody they love, or simply to attach with a good friend…


I learn your papers on peripheral neuropathy yesterday, 5 treasured hours of my life that I’ll by no means get again. [laughs] Memorising info after which regurgitating them in 5000 fastidiously crafted phrases shouldn’t be science individuals, it’s mental bulimia. Actual science occurs after we discover what we don’t know: Galileo, Curie, Einstein, all of them had the creativeness and the center to take a look at a set of info and say, ‘okay, however what about this? And what if that? They requested questions. As a substitute of revisiting what we already know, let’s spend this hour in pursuit of ignorance, our personal.



Consider your life as a narrative. Really you already do. FMRI research present us that following a narrative, with a starting and center and finish, causes our brains to launch cortisol and oxytocin. These chemical substances give us the uniquely human skill to attach with somebody, even a complete stranger, and empathise. In different phrases, tales are what we use to seek out that means in our lives. Now think about for a second that we lived with out the understanding that our story should ultimately finish, what if our lives had been as infinite because the universe, if the ticking clock by no means stopped. What would our story be then? Would we nonetheless love? Or care? Would these tiny fleeting moments that imply every thing, imply something in any respect?



A person loses each legs and will get robotic ones that he can energy along with his thoughts, a gaggle of child geese settle for the zoologist as their mom, and Lewickie [professors assistant], having a tough time discovering romance, turns to a digital intercourse simulator created by an grownup toy firm in Japan. Prosthetic limbs, filial imprinting, Japanese intercourse robots… what do all of them have in widespread? They’re all replacements. From limbs manufactured from metal and wires, to moms who aren’t even the identical species, to extremely developed self pleasure gadgets, so far as the mind is worried, if it will get the job executed, does it actually matter if it ain’t the true factor?



What number of of you’ve got heard the time period ‘mommy mind’? For generations girls have been advised that having kids will flip their brains to mush. That the calls for of motherhood will trigger them to spiral into senseless behaviour like placing the keys within the fridge or the milk within the closet. However the truth is, current research present that new moms develop sure cognitive enhancements, the Hypothalamus, the Amygdala, and the pre-frontal cortex truly develop publish partum, these areas inspire a mother to take care of her toddler, to benefit from the easy interplay, and to be simpler at abilities like reasoning, planning, and judgement. Put one other means, love grows a moms mind, actually. However what about dad’s? Males’s testosterone ranges drop by a couple of third within the weeks following their little one’s arrival, making them extra nurturing, much less aggressive… however earlier than you guys begin panicking concerning the different facet impact of low T, simply understand that your spouse will in all probability be extra involved in your child than in your child maker. As superb as these mind makeovers are, all of the neurobiology on the earth can’t clarify the enjoyment that comes from holding a new child. Or from witnessing the miracle of latest life.



What number of of you’re elitists? No person? These designer denims, are they actually value 200 bucks? And also you, basketball Jones, do these customised hightops make you soar like Lebron? Intelligent advertising has conditioned us to consider that we get what we pay for. In reality researchers at Stanford used an MRI to gauge mind exercise whereas members sipped samples of purple wine. Guess what they discovered – when individuals thought that they had been consuming 5 greenback merlot, the medial orbitofrontal cortex, a part of the mind concerned with pleasure and reward was minimally energetic. However when advised that very same wine was a 100 greenback bottle of Chateuneuf de Pape, the pleasure centre lit up just like the Las Vegas strip. Which tells us that despite the fact that we’d not be snobs, or medial orbitofrontal cortices are.



Why are breakups so rattling excruciating? Possibly as a result of every thing reminds you of your lover. And therefore your loss. Listening to your favorite Smiths music on the radio, consuming scorching canines on the lopsided park bench the place the primary I really like yous had been spoken. It’s no marvel you’ll be able to’t go 24 hours with out bursting into tears. When individuals see pictures of their family members, the caudate nucleus of their basel ganglia floods with dopamine. Nicotine and different medication additionally stimulate will increase in dopamine, in order that whenever you attempt to stop smoking or sugar, your mind craves that substance, the identical means it craves the one who broke your freaking coronary heart. You’ll do loopy idiotic issues to get your repair – that’s as a result of whenever you’re in like it’s not ‘as if’ you’re an addict, you’re an addict. Actually. As everyone knows, going chilly turkey is a bitch.



[this is a work in progress… so forgive typos, and slight errors in text, and the missing quotes of the final episodes, they’ll be up soon….]
