| Abstract: | Resting frontal alpha asymmetry measures the relative activation intensity across the left and right frontal regions that represent emotional experience. Here, the focus is on levels of alpha asymmetry between high‐ and low‐neuroticism females across the menstrual cycle. Resting alpha asymmetry in healthy females who scored high or low on neuroticism was assessed during the menstrual phase, the late follicular phase, and the midlate luteal phase. High‐neuroticism females exhibited lower relative left prefrontal activity than did low‐neuroticism females during the midlate luteal phase, as indexed by alpha1 and alphaTotal asymmetry scores at the prefrontal electrode positions (FP1/2). EEG results demonstrate that the resting frontal alpha asymmetry of high‐ and low‐neuroticism females was moderated by the menstrual cycle, and high‐neuroticism females should pay particular attention to their emotional experience during the midlate luteal phase. |
