- At the micro-scale the brain is a mess; a thick tangle of nerve cells connected at synapses. Mapping just a tiny portion of this mess, a few hundred cells, is a huge challenge. You have to wonder if it's worth the effort. But seeing exactly how brain cells are wired together is giving us new insights into brain function. The researchers who made the 3D maps in this video discovered a new type of cell and worked out how insects see movement. If you've ever tried to swat a fly you'll know how good they are at sensing motion!
Read about the three studies on our website: www.nature.com/... - วิทยาศาสตร์และเทคโนโลยี
I came for more answers; but all I receive is more questions...
welcome to science...
+Davey Webb or does science welcome me? Lol I study Biochem which at first sounded easy but trying to understand everything is a Herculean task. 😛
Same here.... The molecular process doesn't fit to me
Have some DMT , you'll get all the answer's you need
Curious how the human brain doesn't fully understand how it works
+BrandonWillWin
Not fully. But two years ago, I started to have a comprehensive understanding and since it has much developed. A handful of different, complementary views on the subject, two of which detail the "what" and "where" paths in depth, conceptually.. Unfortunately writing on it all is a much more formidable task for me. But I will get it somehow.
+BrandonWillWin Descartes wondered the same thing, and conceptually, we aren't that far ahead of him
+Pocari Sweat We can reasonably credit all of modern scientific methods to Descartes, and more so Bacon.
+BrandonWillWin without the aid of collective work with other brains, without computing machines and other instruments it's a logical impossibility. but i believe there will be humans in the future that will have the amazing chance of peering into their own inner workings. of course, the average mind cannot even keep up with current day scientific efforts.. so for the majority of us we will have to settle with oversimplified explanations. here's a very interesting aspect of the brain that most brains are capable of understanding. altho certain biases prevent it from happening - anywherein12seconds.tumblr.com/post/144388146011/is-our-skull-beyond-the-sky-look-around-you-is#notes
“If our brains were simple enough for us to understand them, we'd be so simple that we couldn't.” - Ian Stewart
That is 20 years of human effort by a single person.
30,000 / 6 hour of useful work per day = 5,000 days
5,000 / 5 days per week = 1,000 weeks
1,000 weeks / 50 useful weeks per year = 20 years
It´s increible!!
When you watch, neurons painted. The lessons about brains...
It´s understandable :)
Connectomics! Great concept :)
This is SO amazing, I love it! I just thought it was a little doubtful that a fly's neurotransmitters were divided into four types, responding to the four cardinal directions. I don't know why this feels weird to me. I'm not really questioning it, though. It just doesn't sound right to me.
What puzzles me too is how the Brain is capable of 'seeing' in 3D. The synapses must be either working faster or AT the speed of light in order to achieve such a thing. If not, everything would look 2D to us. And even more so, imagine if a person's brain processed information with a time delay of 5 seconds. It would be a paradox in itself. Imagine slapping a person on the cheek and then tying the person's hand so they can't move their hand after the event has happened. Would they see and feel everything the same since the brain process is just delayed by 5 seconds? The actual physical damage has occurred but their brain won't notice till 5 seconds later.
The brain can see in 3d because we have 2 eyes. It's much slower than the speed of light. People have quarter of a second delay to pain when surprised
Also when you chop off your hand you feel it 1/4 second later. The delay just isn't noticed. Like how your brain doesn't see your nose unless you wiggle it. It's hidden.

I’m not chopping my hand again, that’s for sure. Hurts like crazy and it’s hard to put it back.
Song track in this video is the song you hear on the free app called infection and infection 2
+Haydor Swagner i can never get cuba
+Haydor Swagner I thought it was Pandemic, but yes!
lol am I the only one who was actually relieved by his textbooks using the words "may" when it comes to neurology ?
Fantastic video!
simply amazing
this is super amazing
Amazing work and a great example of scientific collaboration. Let's get started mapping the human brain.
I'm high yo
The brain doesn’t deteriorate from cannabis.
Cannabis helps maintain a healthy brain! Wake and bake baby 😁
Hi alexgmcm - the link should be working now. Sorry about that.
Dont hug me im scared
then why u holding that big ass knife u lyin shit!!
This, THIS is why I read Nature.
For me, after this video .... there is a perfect creator.
The music at the beginning was taken from a video game :) I wanna say it was back ops. But I'm having trouble pinning it down
You're probably thinking of "Infection", which is a rip off of "Plague Inc".
I heard it in some game on the App Store. It was called infection I think. Where you create a virus or disease.
It took me forever to remember where I heard that song.
NoahTheJerySpringer It's called Pandemic!
mind blowing
This is very interesting
Hopefully one day we will crack the mystery of our brain!
I did! Simple and complex at the same time, but not so complex to understand after all. It helps if you have some sophomore-level maths.
Very new perspective
great video
There is no direct connection s between two far away neurons at first, that's why we have to find a link between two neurons to memorize their connection. Slow but successful. Or creating event memory that stimulate a neuron network for stronger connection.
great stuff!
No, because the education system (as I recognise it in Germany) is not able to make students be interested in or even love science. In the elementary school, there are too little and too bad educated teachers which often get stressed with all these big classes - after finishing elementary school, ca. 97% of all students think of school as something bad which makes no fun. That's getting me angry all the time, because I know how wonderful it is to take part at knowledge! Poor children… :-/
hah, i might actually be the next generation of neuroscientists. Cant wait to start studying cognitive science this year =)
I bet improving the computer's algorithms would take less time than that.
nice
How brains see
I start grad school in Neuroinformatics/Computational Neuroscience in a month... future neuroscientists unite! :P
The nature link doesn't work for me?
I was relying to the beauty of brains, not your laptop screen. Thought you ment some kind of god thingy by "a perfect creator".
Brazil!
ooh trippy
we actually see through our third eye...
Very neat video. I intend to search out this entire series in support of the +Coursera and +Icahn School of Medicine at Mount Sinai #MOOC
That's like 3.4 years lol..
sure, NATURE.
....
Dude....where am I?
on TH-cam
Cool
watch wile high
EyeWire!
How to use your students to publish reserach by nature video.
wow
Of course the Female Brain is very much different .
Much less synapses and very few wiring to be mapped.
That's unfortunately true. :'(
i dont understand
Why the fuck has this Video only got 26000 views???
Cus people have other interests and careers you dumb fucktard
80.000.000
Pretty sure the retina isn't part of the brain...?
The retina is part of the brain.
it's placement and light sensing abilities make it special, but it is brain
The Game is called EyeWire: eyewire.org/
Play EyeWire to map the 3D structure of neurons and contribute to revolutionary crowd-sourced scientific discovery from Seung Lab at MIT.
okay cool so uh how do brains see?
explains nothing about how we see.
It's very interesting. One little nitpick - the "fruit fly" they show is clearly a honey bee.
No, that's clearly a fruit fly... not sure how you can confuse that with a honey bee

the last five videos I've watched had a British narrator. No offense to the Brits but damn does your accent get annoying real quick. They do come across more informative, though.
Not to me
I'm not religious, but, no. Don't be rude
Nature? Really? Do you lack imagination? Are you trying to tell us that you know with an absolute certainty of this? Ironically, you seem to be assigning attributes of conscious choice what you claim to be random and impersonal.
Do you lie on yourself ?
It will be the worst answer to say that my laptop's screen was designed by "the nature"? so what do you think about your eyes?!
The science tells you how, but it will not tell you why or who.
There is no religion in this, but a mind.
Whats up with the contrived goofy sounding brit accent in all these nature vids?!
Unfortunately, many seem to prefer ignorance.
