Abstract
The CNV was studied under baseline, total sleep deprivation and recovery conditions in eight subjects using a 4.5 sec fixed foreperiod (S1-S2). The warning stimulus (S1) was a click; the imperative stimulus (S2) was a set of flashes. During baseline all subjects developed the CNV during the 4.5 sec foreperiod. One night of sleep loss decreased the CNV, and 2 nights of sleep loss abolished the CNV. The CNV wave was examined in three ways: (a) the univariate zero-mu t test which was applied repeatedly at various points during the 4.5 sec foreperiod; (b) the multi-variate zero-mu Hotelling T 2; (c) correlation between paired CNVs. The Hotelling T 2 showed the loss of the CNV during total sleep deprivation.
