Using 144 terabytes of RAM, scientists simulate a cat's cerebral cortex based on 1 billion neurons and 10 trillion synapses

Cats may retain an aura of mystery about their smug selves, but that could change with scientists using a supercomputer to simulate the the feline brain. That translates into 144 terabytes of working memory for the digital kitty mind.

Long-term memories are formed by proteins in brain cells

Using brain cells from a lowly sea slug, which actually makes a good model for our brains, images were captured of proteins forming between the neurons. These proteins distinguish the memory as a long-term one rather than short-term, as the proteins solidify the memory in the neurons. This process had been suspected but not visualized until now.
