The ability of rats to detect or discriminate a series of gaps in continuous noise under conditions of unilateral or bilateral reversible inactivation of the auditory cortex (AC) is studied with the aim to explore the hemispheric lateralization of acoustical signal processing in non-human mammals. The results showed that muscimol-induced reversible inactivation of the left AC suppresses the ability of rats to discriminate between acoustical stimuli of different temporal parameters, whereas inactivation of the right AC results in no change or only a mild decrease in discrimination ability. Our findings demonstrate that, similarly as in humans, the left AC in the rat plays the dominant role in temporal discrimination.
