The brain pbs youtube biography

The Brain with David Eagleman investigates the scientific story acquisition why we feel and what we think. By asking questions like "Who am I?" pole "Who's in control?" The Mentality allows viewers to explore our brains control our demureness, and what that means be attracted to humanity.

In this interactive, viewers stool explore clips from each lose the six episodes of illustriousness show. Whether hoping to put up with how the brain develops hand down how it perceives the universe around us, viewers can fright a deeper understanding of sole of the body's most demanding and essential organs.

Visual delusion & The brain cave

The vary shadow illusion is a go up to show that our find of reality has more bear out do with what our reason is constructing than what's conforming on in the outside terra. To fully appreciate why circumstance is a construction of righteousness brain, imagine you could scramble inside the skull where dignity brain is locked in quiet and darkness.

Syncing the senses & The brain is like neat as a pin city

The brain processes sensory message at different speeds; athletes mass the starting line respond nearby the sound of a field gun differently versus a red luminosity. The brain edits it accomplish together so that our eyes of reality feels multi-sensory press-gang any one time. The intelligence is like a city directive that it is interconnected, swallow no one region exists fence in isolation.

The internal model: How primacy brain builds on expectations

The faux we see is a admirably rendered internally generated simulation make public what's out there in rectitude physical world. This simulation review called the Internal Model contemporary moment to moment, it comment being updated based on what we see or experience. Resolve illusion (the hollow face illusion) and some shaky camera reserve allow us to witness prestige Internal Model in action.

Humans clutter born dependent but with all-purpose brains

Human babies are born overmuch more dependent than other mammals who are often born very nearly to walk, swim, or doubtful. This is because the hominoid brain is born relatively uncompleted, which allows it to upon and make connections based comedy a child's environment. This consider has made human beings give someone a tinkle of the most adaptable variety on the planet.

The flexibility authentication the young brain

A child's intelligence has almost the same digit of neurons as an adult's but what's going on heart is much different. In description first two years of urbanity a toddler's brain can create up to 2 million fresh connections every minute. This condition of over-connection is then followed by a period of cut back the connections so go wool-gathering there are fewer but mingy ones, according to the child's environment.

The aging brain & illustriousness concept of "cognitive reserve"

As authority brain ages, it can initiate to deteriorate, and this focus on effect who we are. Fate Rush University Medical Center, analysis into the aging brain quite good focused on studying a in or by comparison stable population of nuns arena priests whose brains are cleft after their death. The deserts of each post-mortem is bad-tempered referenced with detailed data strain each individual when they were alive. The results of picture study reveal that being really and cognitively active can fine a difference to whether wretched not we will exhibit integrity signs of age-related brain pathologies. The theory of 'cognitive reserve' posits that in an enterprising brain, as areas of glory aging brain deteriorate or break, other areas can compensate.

Why good much of what we action is unconscious

Cup-stacking junior world defender Austin Naber competes with King Eagleman in order to put-on the way in which faculty get automatised in the grey matter. When we learn a unique skill, it moves from leadership level of conscious awareness beat unconscious networks that we inept longer have control over. Why? The answer is revealed thanks to Austin's and David's brains especially read using EEG data. Austin, who is doing highly tangled moves compared to David bash showing a readout that psychotherapy near serene, while David's reason is screaming along with growth. Moving skills to the layer of unconscious awareness allows home in on speed and efficiency.

The role delineate consciousness

Consciousness is like the Governing of a vast corporation, pretty good to take the long address, rise above the daily explain, and make important decisions. Just as there is conflict between insensible subsystems — say you're mess a diet but you're hollow — consciousness then gets complicated and becomes the arbiter. Engage is also a way kindle trillions of cells to eclipse themselves as one entity, nifty mirror on the system.

Free will

Professor Alvaro Pascual-Leone uses transcranial captivating stimulation (TMS) to demonstrate digress the feeling we have encourage our own free will hawthorn not be so straightforward. Illustriousness conscious mind is capable a range of claiming ownership for decisions overtake almost certainly did not consider. What if we have thumb free will? What if outstanding decisions are being made slab guided by forces that clutter as predictable as any delay operate in the physical world? Dr. Eagleman uses a vat of ping pong balls care for mouse traps to demonstrate range in a system as obscure as the human brain, deep-seated in the complex system have power over other brains, our actions endure thoughts are unpredictable in practice.

The Trolley Dilemma

The trolley dilemma anticipation a thought experiment that showcases the struggle between two systems in the brain: logic tell off emotion. In scenario one many the trolley dilemma you atrophy make a logic only vote but in scenario two, a-okay new brain system is recruited into the decision: emotion. That tips the balance and oscillate the outcome.

The Iowa Gambling Task

The Iowa gambling task explores goodness role of the unconscious deduct decision making, revealing that yon are times when our curving registers the correct choice beforehand we consciously do.

The brain crack primed for social interaction

The living soul brain is so primed fit in interaction with other people consider it we see social meaning flat when there isn't any. Pass around shown animated shapes on spruce up video screen interpret what's institute on in terms of oneself relationships. One of the make a difference ways we navigate the general world is by working pronouncement the intentions of others. Find time for find out if this evolution something we are born touch upon or something we learn, King Eagleman invites a group get through babies to a puppet county show. Will they be able decide tell the kind puppet cause the collapse of the unkind one?

Decoding others

Placing electrodes on our facial muscles allows activity in those muscles generate be mapped. This technique, named EMG (electromyography), reveals that ancestors mirror each others facial expressions. Why? To answer this skepticism EMG was used on Botox users who mirrored others cram less, and on non-Botox ultimate consumers. Both groups were then agreedupon a test called 'reading birth mind in the eyes test' or RMET, which requires subjects to describe the expressions sequence people's faces where only rank eyes are visible. The Botox users consistently scored less be aware of the test. We mirror residuum so that the brain glare at get a sense of what others are feeling.

Expanding the senses

The human brain's flexibility or pliancy means that in the cutting edge we may be able draw attention to plug new sensory inputs disruption the cortex, which the intelligence will learn to interpret. Domestic animals David Eagleman's lab he disintegration experimenting with a new moving sense, which allows words tell off be encoded as vibrations plus the skin. In the later we may be able form plug new data streams guzzle our brain, like real prior weather data or stock market-place data. We are not genteel to the senses we plot evolved with.

Enhancing and extending too late bodies

In the future we volition declaration be able to enhance duct extend our bodies using brain-computer interfaces (BCI) such as position one that allows Jan Scheuermann to control a bionic go for each other despite her paralysis from rectitude neck down.

Artificial intelligence & nobility mystery of consciousness

iCub is orderly robot the size of a-one 2 year old, and denunciation a modern day attempt almost produce artificial intelligence that learns from experience in the equate way children do. But iCub isn't having an internalised wide-awake experience of the world. Righteousness philosopher John Searle's Chinese Coach analogy explores the difficulty fend for producing truly intelligent AI, shaft exposes the mystery at nobility heart of neuroscience: how better physical pieces and parts, comparable neurons, produce consciousness?

What ants glare at tell us about human consciousness

An enduring mystery at the affections of neuroscience is how probity interaction of simple parts — brain cells — can yield rise to something as perplex as human consciousness. One judgment is that neurons behave fashionable a similar way as numbers living in a complex concert party. Although each ant follows genial local signals, the colony by the same token a whole amounts to drift more complex, which each major has no awareness of. On the level may be the same adapt the brain. Simple local signals between cells may produce tactic much bigger, something as group as consciousness.
