Auditory information processing at the cortical level
... The primary auditory cortex appears to be well organised with respect to frequency and carries on its surface a “map” of the cochlea, as is found in the subcortical nuclei. High frequency excitation, orignating in the base of the cochlea, is received in neurons located in the more medial portion of ...
