Many brain disorders vary between the sexes, but how biology and culture contribute to these differences has been unclear. Now Northwestern neuroscientists have found an intrinsic biological difference between males and females in the molecular regulation of synapses in the hippocampus. This provides a scientific reason to believe that female and male brains may respond differently to drugs targeting certain synaptic pathways. “The importance of studying sex differences in the brain is about making biology and medicine relevant to everyone, to both men and women,” said Catherine S. Woolley, senior author of the study. “It is not about things such as who is better at reading a map or why more men than women choose to enter certain professions.”
Among their findings, the scientists found that a drug called URB-597, which regulates a molecule important in neurotransmitter release, had an effect in females that it did not have in males. While the study was done in rats, it has broad implications for humans because this drug and others like it are currently being tested in clinical trials in humans.
