Circadian fluctuations in glucocorticoid level impact perceptual sensitivity

Perceptual abilities fluctuate on time scales of seconds or minutes. However, it is unclear how slower, circadian neurobiological rhythms such as the expression of glucocorticoid (GC) hormones modulate our perceptual abilities. Here, we show that phasic, moderate increases in GC availability prove beneficial to auditory discrimination. In an age-varying sample of N = 68 healthy human…
