Rats were exposed to intense five-per-second synchronous clicks and flashes from birth to adulthood. Electroencephalographic recordings showed an abnormally high incidence of high-voltage burst activity in the visual cortex and thalamus of the animals; wave frequency within the bursts was five per second instead of the normal seven per second
