Abstract

The use of Event-related potential (ERP) in measuring the degree of sleep disturbance caused by obtrusive acoustic stimuli is discussed. ERPs allow the researcher to monitor the processing of auditory input even when the subject is not conscious about the presence of a stimulus. It is observed that processing of external stimulus must be inhibited in order to sleep. It is also observed that at the sleep onset, consciousness of the external environment and internal mental state is graduaIly lost. It is suggested that the negative wave (N1) is generated in the auditory cortex whereas the switching of attention associated with the positive wave (P3a) may be a function of the executive control system of frontal lobe.
