  • Abstract
  • Look Inside

A historical episode for a discovery of the auditory cortex is first described. The definition of the primary auditory cortex is discussed and then problems of the concept explaining the simple tonotopic organization are pointed out. Then, findings on cortical responses to frequency modulated sounds, temporal information processing and pitch information representation are discussed. Data indicate that performing conventional static frequency analysis appears to be much less important. Cortical functions to process dynamic temporal patterns of sound stimuli are strongly emphasized.
