Press Releases on the Brain
This month's Press Releases from Nature Neuroscience are interesting reads. There's a lot of imaging data, so take it for what it's worth, but it is, nonetheless, interesting.
Wiring the brain for depression--From Dan Weinberger's Group at the NIMH. This group has also discovered a gene variant that may be linked to some of schizophrenia's negative symptoms, and their data are usually interesting since they combine imaging techniques with molecular methods and mice models.
Race-related brain activity--"Pictures of African-American faces are known to activate the amygdala more strongly than Caucasian-American faces, at least in Caucasian-American people, but the underlying reason for that activity has remained controversial." That's your hook for this one.
Brain changes over the menstrual cycle--well, duh...actually, it's interesting stuff. These studies arise from data on catamenial epilepsy, a condition in which seizure activity is modulated during the menstrual cycle in epileptic women. Hormonal-linked-seizure activity in women is really interesting--some women go through most of their life never having a seizure, yet when they enter menopause, they become epileptic. There are also cases of young girls becoming epileptic when they first start menstruating or when they first get pregnant.
