Women in mind
The volume of a woman’s grey matter changes during her monthly ovulation cycle. We know a woman’s mood and emotional state vary at different times of the month (Â鶹´«Ã½, 29 October, p 18).

Low oestrogen coincides with a slight increase in the cingulate cortex and raised oestrogen with increases in the prefrontal cortex, left hippocampal gyrus and amygdala.
