Research points to genes that may help us form memories

Gene expression within neurons is critical for the formation of memories, but it's difficult to identify genes whose expression is altered by learning. Now researchers have successfully monitored the expression of genes in ...

Scientists discover a new pathway for fear deep within the brain

Fear is primal. In the wild, it serves as a protective mechanism, allowing animals to avoid predators or other perceived threats. For humans, fear is much more complex. A normal amount keeps us safe from danger. But in extreme ...
