ABSTRACT
The auditory cortex represents the centralmost largely unimodal processing stage of auditory information along the auditory pathway. It seems to be essential, for example, for discrimination and localization of sounds, recognition of speciesspecific vocalization, embedding of acoustical cues into the behavioral context, and auditory learning and memory. The auditory cortex is not a homogenous region; like all other sensory cortices it consists of multiple areas or fields. Each field is commonly defined by a unique combination of anatomical and physiological features and a field border by a rather abrupt change of at least one of these features.
