Study, 2017

# Does menstrual cycle phase affect how the brain responds to rewards when a woman is under stress?

Yes, in complex ways. Cycle phase affects brain sensitivity to feedback and rewards, and stress also changes reward processing. The effects depend on both the phase and the presence of stress.

 Moderate study design

Women with regular menstrual cycles (sample size not reported)

## What they did

Women with regular menstrual cycles attended two sessions: one during late follicular phase and one during late luteal phase. In each session they performed a task involving monetary rewards while researchers measured brain activity using EEG. Half the time they did the task under normal conditions and half under acute stress.

## What they found

During late follicular phase, the brain showed stronger responses to bad performance outcomes. During late luteal phase in control conditions, the brain showed stronger responses to good performance outcomes and potential rewards. Stress decreased the brain's preparation during reward anticipation but increased attention to rewards during positive outcomes. Late luteal phase did not show increased sensitivity to stress compared to late follicular phase.

## What it means for you

The menstrual cycle affects how the brain processes rewards and feedback in ways that might explain mood changes during the cycle. This is a controlled laboratory study with brain imaging rather than a real-world study of mood or behavior. The sample size is not reported.
