Sex in the brain: hormones and sex differences

Contrary to popular belief, sex hormones act throughout the entire brain of both males and females via both genomic and nongenomic receptors. Many neural and behavioral functions are affected by estrogens, including mood, cognitive function, blood pressure regulation, motor coordination, pain, and opioid sensitivity. Subtle sex differences exist for many of these functions that are developmenta...

Oversimplifying Sex Differences in the Brain

Sex differences in the emotional brain.

In this issue, Schienle et al. use brain imaging to examine emotion-related activation differences between men and women. Are those differences related to the way the sexes feel emotions? Are they hardwired? In this commentary, we briefly review sex differences in feeling, perception of emotionally evocative cues, and expression of emotions, and we discuss how they may be related to sex differe...

The bisexual brain: sex behavior differences and sex differences in parthenogenetic and sexual lizards.

The parthenogenetic lizard Cnemidophorus uniparens alternates in the display of male-like and female-like sexual behavior, providing a unique opportunity for determining the neuronal circuits subserving gender-typical sexual behavior within a single sex. Here we report a 6-fold greater [14C]2-fluoro-2-deoxyglucose uptake in the medial preoptic area of C. uniparens displaying male-like behavior ...
