Scientists uncover a difference between the sexes

Many brain disorders vary between the sexes, but how biology and culture contribute to these differences has been unclear. Now neuroscientists have found an intrinsic biological difference between males and females in the molecular regulation of synapses in the hippocampus, a brain region involved in learning and memory, responses to stress and epilepsy. This finding provides a scientific reason to believe that female and male brains may respond differently to drugs targeting certain synaptic pa
