pSEV (peak saccadic eye velocity) is a key measure linked to GABA receptor function and has been studied in relation to menstrual cycle mood disorders like PMDD.
Despite its use in drug studies, there’s a lack of research on how pSEV responds to natural hormone fluctuations during the menstrual cycle.
This pilot study found that pSEV is significantly lower during the luteal phase compared to the follicular phase, suggesting a potential link between menstrual hormones and GABA receptor activity.
