The following study investigated the late auditory evoked/event-related potentials; in particular the P300 under the adverse condition of sleep deprivation. Additionally, a smaller subset within this study analyzed the response of the late auditory potentials after a recovery period. Twenty-four subjects were run in the baseline and sleep-deprived conditions using the P300 oddball paradigm for waveform elicitation. A Smaller subset consisting of 13 subjects were run in the recovery phase. The results revealed an increase latency and a decrease in amplitude once the participants were deprived of sleep. Upon being given a 90-minute recovery period a statistically significant difference was revealed in both P300 amplitude and latency. A rebound to the baseline condition was essentially revealed.
