ABSTRACT
The temporal and spatial information provided by electroencephalogram may be used to understand how the brain implements behavioral change, feeling, and memory. Electrophysiological activity is the origin of behavior or processing by the brain. The peak-interval procedure is perhaps the best method for studying interval timing behavior in animals. The pattern of electrical activity in a fully awake animal is a mixture of many frequencies dominated by waves of relatively fast frequencies and low amplitude. The brains of animals process many sensory inputs from the environment through the eyes, ears, nose, mouth, and skin and control the timing of these sensory processes. In human studies, the timing of stimuli is a very important factor affecting event-related potential's (ERP), even more so for animal studies. Temporal discrimination involves a variety of complex mental operations in animals. Consequently, it is useful to conduct ERP analysis for studying the brain mechanisms involved in timing and time perception.
