Abstract:
:An immobilisation stress (IS) of 2 h applied to rats at the beginning of the dark period (12 h), i.e. when the animals are more active, induces during the 10 consecutive h a significant rebound (+92%) of paradoxical sleep (PS) while slow-wave sleep state (SWS) is poorly affected. Two h of sleep deprivation, also applied at the beginning of the dark period and realized either by the platform technique or by maintaining the animals awake with gentle handling, do not affect significantly subsequent SWS and PS. Finally, when repetitive IS are inflicted to the animals (one IS of 2 h every 3 days) an attenuation of the PS rebound is observed. These data suggest that a qualitative aspect of the waking state as in an intense stressful situation might be the source of a hormonal process inducing a PS excess.
