Rather than distinctly male or female, the human brain is much more like the heart, kidneys and lungs – basically the same no matter the sex of the body it's in.
Abstract Resting EEG, measured in eyes-closed (EC) and eyes-open (EO) states, can provide insight into behavioural differences between groups. Surprisingly, differences in resting EEG between females and males have not been investigated systematically in previous literature. The present study utilised the four traditional EEG bands to confirm their baseline EC topographies and reactivity (EO minus EC) across groups, to clarify topographical differences between sexes, and to confirm alpha as a measure of arousal. Participants were eighty healthy young adults (40 female), with a mean age of 20....
Deby Suchaeri/Getty Images Research has revealed an association between common psychiatric conditions and events occurring during fetal development. A new study now suggests that negative stress experienced in the womb may impact an individual’s response to stressful situations well into their 40s. The results also indicate that exposure to prenatal stress affects males and females differently — and that these effects may last a lifetime. Stress occurs when demands or challenges cause the brain and the rest of the body to react with emotional or physical tension. Stressors can be perceive...
Stress before Birth Affects Midlife Brain Circuits Differently in the Sexes Stress before Birth Affects Midlife Brain Circuits Differently in the Sexes Goldstein’s team observe the brain’s stress response circuitry using a negative stress reactivity task. Functional magnetic resonance imaging (fMRI) depicts brain regions that light up in response to negative stressful stimuli: hypothalamus (green), hippocampus (royal blue), medial prefrontal cortex (magenta), amygdala (red), periaqueductal gray (light blue) and orbitofrontal cortex (yellow) [Jill Goldstein].

Sex-related differences in the brain associated with depression, schizophrenia and bipolar disorder are related to maternal stress during fetal development. This finding points to the need to explore sex-dependent targets for early therapeutic intervention and prevention.
