AMAZING video here.

Slicing a brain to create a digital mind atlas

WOW, but also not sure I'll look at ham the same way again..... :/

Awesome vid, bro...

That's up there with mapping the human genome (All the genetics found within your cells)

[stuck?]

That was certainly neat!

That was a nice video - although the guy operating the cryostat was slicing a little too fast in my opinion.

In this video, it looks like they are doing a Nissl stain, which selectively stains the cell bodies of neurons and glia. A Nissl stain can help you to identify different brain areas from each other, since the cell bodies within a brain area can be organized in rows or densely packed into clusters.

Brain mapping is a pretty cool area of study, especially now that people are developing three dimensional brain mapping software available on the net.

I'm a neuroscientist, so I sometimes have to do brain sectioning and then histology (although I work mainly with rodents, not humans).

If you want another cool neuroscience video, check this out:

Karl Deisseroth - Thy-1::ChR2-EYFP Mouse - YouTube

In this video, scientists are using optogenetics to control locomotor activity in a mouse.

With optogenetics, you use a viral vector to insert a gene called CHR2 into a mouse. CHR2 produces a protein called channelrhodopsin, which is an excitatory channel that only opens in the presence of blue light.

In this example, channelrhodopsin was inserted in the motor cortex of the mouse (on only one hemisphere of the brain), and when the scientists shine a blue optical electrode inside the mouse's brain, he moves in circles.

TLDR: With optogenetics, you can control a mouse's movement simply by shining a blue light in its brain.

Pretty cool, eh?

I remember seeing a program years ago about a condemned (on death row, about to be executed) prisoner who agreed to donate his body to science. After his execution, scientists froze his body and, starting at the top of his head, shaved fractions of a millimeter off at a time and took digital photos, all the way to the bottom of his feet, then compiled the data into a 3D representation of the human body. Made me feel a little sick watching it, TBH

[edit] I guess it was 1 mm slices for the man. They did it with a woman's corpse too, and did .33 mm slices

Believe it or not the one thing I got from that was that he dressed to his left.
