Effect of caffeine on resting-state alpha activity across the human menstrual cycle.

ABSTRACT:

Rationale

Caffeine is the most consumed stimulant worldwide, and there is great interest in understanding its neurophysiological effects. Resting-state electroencephalography (EEG) studies suggest that caffeine enhances arousal, which suppresses the spectral power of alpha frequencies associated with reduced alertness. However, it is unclear whether caffeine's neurophysiological effects vary across the human menstrual cycle.

Objective

The objective of our study was to test whether caffeine's effect on EEG activity differs across the human menstrual cycle.

Methods

Fifty-six female participants were randomly assigned to complete the experiment while in either their menstrual (n = 21), follicular (n = 19), or luteal (n = 16) phase. Each participant completed two study se
