Flipping a single molecular switch can make an old brain young

Scientists have long known that the young and old brains are very different.

A single molecular switch, that when flipped, helps create the mature neuronal connections that allow the brain to bridge the gap between adolescent impressionability and adult stability.

Can Robots Evolve? On Building the “Conscious” Machine…

How would you build a conscious machine? Well to begin with I’d get Life Insurance and then take my brain and put it in a jar and freeze my body. Then hundreds of years later wake me up and transplant me into an IronMan. Yes, I partially got that idea from the movie IronMan and from Futurama. I’m still going to do it though. But more to the point, Christof Koch and Giulio Tononi both have good points of in their articles that they wrote on consciousness and robots.

A Glowing Protein Shows How We Make Memories

A Glowing Protein Shows How We Make Memories

A new strain of genetically engineered mice has allowed researchers to pinpoint, for the first time, the precise cellular connections that form as a memory is created. By tracing a protein tagged to glow fluorescent green as it migrates through individual neurons, from the cell body out through the branching dendrites, the researchers could see exactly which synapses–connections to other neurons–were involved when the mice learned to fear an electric shock.
