Heart rate variability (HRV) has become an increasingly popular index of cardiac autonomic control in the biobehavioral sciences due to its relationship with mental illness and cognitive traits. However, intraindividual stability HRV response sleep diurnal disturbances, which are commonly reported illness, executive function not well understood. Here, 40 healthy adult males we calculated high frequency HRV-an parasympathetic nervous system (PNS) activity-using pulse oximetry during brain imaging, assessed attentional performance a subsequent behavioral test session at three time points: morning, evening, following morning. Twenty participants were randomly selected for total deprivation whereas other 20 slept as normal. Sleep morning-to-night variation did influence either group or individual level; however, abolished between orienting attention HRV. We conclude that day wake night laboratory-induced do alter supine young male adults.
