Picture a star-shaped cell in the brain, stretching its spindly arms out to cradle the neurons around it. That's an astrocyte, and for a long time, scientists thought its job was caretaking the brain, ...

The findings are the first example of electrical brain stimulation in humans giving an event-specific boost to memory lasting until the next day, the scientists say. Direct electrical stimulation of ...

Macaque’s social tolerance grades, through its underlying cognitive demands, shape subcortical structures volumes.
