Survey study, 2013

Does the menstrual cycle change how the brain responds to emotional faces?

Yes, brain electrical activity in response to emotional faces is stronger during ovulation than during the premenstrual phase, suggesting hormone changes affect emotional processing.

Early or limited evidence 29 healthy women

What they did

Tested 29 healthy women during three phases of their menstrual cycle (premenstrual, post-menstrual, and ovulation). They showed women emotional faces and measured brain electrical activity (event-related potentials) and accuracy in recognizing different emotions.

What they found

The late positive potential (a measure of brain activity) was significantly larger during the ovulation phase compared to the premenstrual phase (750 to 1,000 milliseconds after seeing the faces) for all types of emotional expressions. Accuracy in recognizing emotions did not differ by menstrual phase.

What it means for you

Menstrual cycle hormones affect how the brain processes emotional information, but this is a small study in only healthy women with no clear link to daily life symptoms or PMS.
