World Science Festival
Is the human brain an elaborate organic computer? Since the time of the earliest electronic computers, some have imagined that with sufficiently robust memory, processing speed, and programming, a functioning human brain can be replicated in silicon. Others disagree, arguing that central to the workings of the brain are inherently non-computational processes. Do we differ from complex computer algorithms? Are there essential features of the physical make-up and workings of a brain that will prevent us from creating a machine that thinks? And if we should succeed in constructing a computer that claims to be sentient, how would we know if it really is?
This program is part of the Big Ideas Series, made possible with support from the John Templeton Foundation.
The World Science Festival gathers great minds in science and the arts to produce live and digital content that allows a broad general audience to engage with scientific discoveries. Our mission is to cultivate a general public informed by science, inspired by its wonder, convinced of its value, and prepared to engage with its implications for the future.

The World Science Festival strives to cultivate a general public that's informed and awed by science. Thanks to your contributions, we can continue to share the wonder of scientific discoveries with the world.
Aaaaaand 6 years later: , it was Balls BS, can’t be done , human brain computing machine, booo hooooo , shit talk only
Before attempting to map human brain sketch should be started from very low level creatures like ants.
Some jokingly said brain is the 5th dimension, cyber comes after.
Neurotransmitters are endogenous chemicals that enable neurotransmission. It is a type of chemical messenger which transmits signals across a chemical synapse, such as a neuromuscular junction, from one neuron (nerve cell) to another "target" neuron, muscle cell, or gland cell.[1] Neurotransmitters are released from synaptic vesicles in synapses into the synaptic cleft, where they are received by neurotransmitter receptors on the target cells. Many neurotransmitters are synthesized from simple and plentiful precursors such as amino acids, which are readily available from the diet and only require a small number of biosynthetic steps for conversion. Neurotransmitters play a major role in shaping everyday life and functions. Their exact numbers are unknown, but more than 200 unique chemical messengers have been identified.[2][3][4] Wikipedia
18:37:…no ! no ! absolutely NOT !..that's NOT what we want to do ! what we want to do is have an novel type of scanning probe consisting of some form of sub atomic particles so that instead of just physically slicing up a brain, we just SCAN it, so that we get a true, accurate , and very fast 3D representation of the brain ! the advantages of this are obvious, but it goes even further, it could, if done fast enough with this kind of tech, also be considered a 4D representation because time is relevant, as the brain is always changing due to the dynamics of input and output, memory etc etc.
we are in deep deep deep trouble….can you IMAGINE the size and ramifications of the lawsuits against humans when rats and mice finally become intelligent ?!….boy are we in for it….
I really like this!!
damn. I can really sit in my room and watch this what a time to b alive
They need to start small, say, with Donald Trump's brain …and progress on upwards to a rat brain…

33 degree CONtrol Freakmson Satanic Agenda Criminal elite Cult Clubs BullShit. Scientists are Selected ActWhores. They know Everything about the brain since they CONtrol the world. Typical Freakmasonry and elite Gar Barge!!

This was pretty good to watch, seeing the brain visualized this way prompted me to think of it as some kind of bio chemical internet, with the glia being the gateways – deciding which meshes and topology to use to approach a problem (which branch of neurons to use). I can see it's more complex than that, although seeing how this subject is moving on is neat, as it helps me to think of things differently
Fucking music. Thumbs down and bye bye.
they could of at least given them a table for their drinks instead of having them on the floor.
Brain and Mind is not the same thing.
Hmm, all the while I was watching this video, my little voice in my head kept saying, " This is me! WTFFF!!!!"
Glial cells sort of remind me of "dark matter" in the universe.
So how does the brain work?
19:00 That was a great process, I'm so high and I envisioned the same idea right before you explained it 😉
Uh… that’s not what it is…… I see why suddenly everything is so dumbed down…. uhh you can’t build a brain… World Science Festival?…. wow. 😐 all of these are super stupid theories coming from nowhere…
Cant wait for Glia transplants
Has anyone realised that the most of the panellist in World Science Festival are the white westerns? Whereas according to WIPO 2015 after China, USA, Japan and South Korea are the leading patent applicants.
interesting
Interesting
Very nice program
54:59 – Beware, Gregory Wheeler (far left) makes a huge mistake. He quotes Richard Dawkins (correctly, but out of context), then interprets him completely wrong. Wheeler probably didn't read the book. Dawkins 100% agrees with Wheeler that the idea of someone making math calculations to catch a fly ball is ridiculous. Dawkins entire book (literally) — and his entire life's work!! — is an argument to demonstrate how absurd that notion is. (All his anti-religion stuff is irrelevant here). Wheeler needs to do his homework.
What intermediaries can we look to in understanding the human brain?
Thank you Colleagues and New York for your analysis and support of this very important subject :), peace and love, Doug.
Wow, epic interesting knowledge about the human brain + science building knowledge : unlocking innovations with insight! The lever of riches being pulled by neurosciences that will pave the way to deeper integration between the human brain and digital computers!
The machines we build would not necessary require built in (on purpose) errors since we are prone to errors anyway. Only a machine built by another machine would require some sort of error or number of degrees of freedoms in certain decisions.
It's pretty arrogant to think these people can reconstruct or simulate the brain when they can't make a knee joint that can mimic or reproduce the function of a real knee. I speak from experience as an amputee who no longer has a functioning knee on my left leg or what's left of my left leg. To even come close they would first have to create a power system that would be light enough with power supply enough to be away from a power source for recharging. The Swiss have done wonders with hydraulics and valves but not even near what could be called fully functional knee. Computer circuitry and servos are getting smaller and more powerful but durability is the problem same with material that can endure the massive forces the moving parts are subjected to. Of course, cost will always be a limitation when dealing with cutting edge technology and fabrication or manufacturing. The complexity in what a knee joint is called on to do to run and jump is unbelievable as can be seen in athlete's career ending due to an injury of a knee not lost of a knee.
In the end a knee can be considered more mechanical then a brain which could be considered electrical circuitry. In the end for a knee to work fully it takes both the brain and knee to work in conjunction with many demands made on demand not reflexsively or unconsciously. So please, the arrogance of these scientists and doctors are breathe taking.
they fucking about with my brain mass chipping thats why i will never win its allready so sophistacated hes fabracated bullshit mate
bruce waysne is the moderator
If you create a model of the human brain in a computer exactly, would it be conscious? …No.
The host is hot
1 neuron has processing power of one laptop? whaaaaaaaaaaaaaaaaaaaaaaaaaaat? O_o
Brain from a rat! Here we go again the animal testing supposed gleaning info from a rats brain versus a human brain, I don't think so.
anyone know the song at 12:00 ?
This shit is old, or the participants are dinosaurs not up to date..
