onconsciousness:

Brainbow is a term used to describe the process by which individual neurons in the brain can be distinguished from neighboring neurons using fluorescent proteins. By randomly expressing different ratios of red, green, and blue derivatives of green fluorescent protein in individual neurons, it is possible to flag each neuron with a distinctive color. This process has been a major contribution to the field of connectomics, or the study of neural connections in the brain.

The technique was originally developed in the Spring of 2007 by a team led by Jeff W. Lichtman and Joshua R. Sanes, both professors of Molecular & Cellular Biology in the Department of Neurobiology at Harvard Medical School. Their demonstration of the technique in mice first appeared in the November 1, 2007 issue of the journal Nature. The original technique has recently been adapted for use with other model organisms including Drosophila melanogaster and Caenorhabditis elegans.

If the word “brainbow” is a real thing, my life is pretty much complete.

The split brain: A tale of two halves

Since the 1960s, researchers have been scrutinizing a handful of patients who underwent a radical kind of brain surgery. The cohort has been a boon to neuroscience — but soon it will be gone.

  Scientists ‘See’ YouTube Videos in the Mind
What if what you saw with your eyes could be interpreted in a brain-scanner? Well, that just happened. Check it out:

Gallant’s coauthors acted as study subjects, watching YouTube videos inside a magnetic resonance imaging machine for several hours at a time. The team then used the brain imaging data to develop a computer model that matched features of the videos — like colors, shapes and movements — with patterns of brain activity.
“Once we had this model built, we could read brain activity for that subject and run it backwards through the model to try to uncover what the viewer saw,” said Gallant.
Subtle changes in blood flow to visual areas of the brain, measured by functional MRI, predicted what was on the screen at the time — whether it was Steve Martin as Inspector Clouseau or an airplane. The reconstructed videos are blurry because they layer all the YouTube clips that matched the subject’s brain activity pattern. The result is a haunting, almost dream-like version of the video as seen by the mind’s eye.

A drug that can make your old memories like new

Involves an enzyme.

Sharing because of the amusing comments on the article. For example: “Not recommended for husbands. There’s a reason we try and forget you told us three months ago your mother was coming to live with us.”

lol
