Neuroscience: Crammed with connections

- In a piece of brain tissue smaller than a dust mite, there are thousands of brain cell branches and connections. Researchers from Harvard University in Boston, MA have mapped them all in a new study appearing in Cell. They find some unexpected insights about how the cells talk to each other.

This 3d rendering of a piece of mouse brain shows why neuroscience is so incredibly complicated. We can only hope that technological advances will eventually help us understand the human brain but it sure won't be easy.
Have you looked into deep learning? Really interesting stuff where we're able to train statistical learning algorithms to do the kind of stuff that we do (i.e., speech/facial recognition).
Scientist Sam haven't, sounds cool
You know you're a nerd when you come across a video like this and realize you've already seen it haha. Anyway I love a good rerun.
Impressive neuroscience pursuit.
Wow! So this is how brain mechanics work. Imagine making a machine, so complex.
But the cortical colluns are all equal right? maping only, then one you map all the brain?
Great work. However how much effort and technology is needed to dissect further parts of the brain
good job,great video
Awesome
Decent work but I suspect that it will be more rewarding to analyze the code rather than look at the complex 'final' production. As good as this spatial data is, it doesn't reveal how the layout changes and grows.
Through piece wise simulation it should be possible to understand the genetic code, and abstract above the parts dealing with the 3D spatial limitations and only look at the higher level algorithms. If you want to understand the intelligence aspect of course.
Dan Frederiksen What is currently known about the code links viruses to all pathology and nutrients to healthy longevity because nutrients are required to link the physiology of reproduction to cell type differentiation, which is perturbed by viruses.
See what's been known about the code for more than 30 years: rna-mediated.com/the-darwin-code-by-greg-bear/
Eugene Koonin just commented on the importance of understanding the role played by viruses in this interview: Riding the Evolution Paradigm Shift With Eugene Koonin www.huffingtonpost.com/suzan-mazur/riding-the-evolution-paradigm-shift-with-eugene-koonin_b_7217216.html
"...the new understanding of evolution needs to integrate what we now know about viruses and virus-host interactions which, from my own
perspective, has been absolutely one of the key factors of all evolution
since the emergence of cells -- well, actually even before the
emergence of cells."
jvkohl but that's only pertaining to design limitations and immunology, right? not to understand what techniques the brain employs to achieve intelligence.
Quietly hoping that Super AI will happen in my life. But this video makes it feel like it won't be :( Wahhhhh!
I don't think we have to know the structure of the brain to understand how it work. It can be the proof of theroies.
[Man-in-the-sky]damn! that's cool.
Why would a mouse require so much?
Why are you thinking that a mouse shouldn't require such complexity ??
Unlike the prevailing view maybe Brain is easy to understand.. just maybe. I'm just saying
the brain does not understand how itself works. Brainception...
good Video
fanjapanischermusik yes it (we) can. Just not yet.
you can't say you understand something in the future, but not now. this is like saying to a teacher at school:" sure i have done my homework, but not yet."
i just woke up and you throw this at me..... my brain wants to puke.................

lol at least you're funny.
thx

Well, our critical thinking of how neural systems interact; we are making slow headway, but headway none the less. Just look at how we discerned what constituted that small piece of neural tissue. We are already trying to mimic the brain by building a physical construct having different hubs interact with each other similar to how ours work. IBM is a leader in this. Will we make it as efficient (yes on this part) and compact? not now; but even if not ever, who cares. The doing is in the trying. Hell, AI is almost a reality. More than anything, what limits robotics isn't the brain part, it's the body part.
wow😍
brain
Science Science Science
God science rules!!! #Geeklife
interesting video! but memory obviously isn't only created by the cortex. and also calling its computations "more sophisticated", when nobody can really computationally explain an entire complex brain function at the moment - whereever it may be localized -, seems a bit vacuous.
WHOA
I do not believe in evolution
lol love you guys too. i do however believe in triggered adaptations from preexisting information.
