• The single unit analyses have been done in 180 cortical auditory neurons of the cats.A new type of response area was found besides the flat type and the sharp peak type.The neurons of this type had multi-peaks in their response area, sugge-sting the direct projection of afferent fibres from the neurons of the medial geniculate body.Mean latency of the neurons of the flat type was the longest, followed the multipeak type, and the sharp peak type.The neurons obtained from a vertical penetration had the same characteristic frequency, and was presumed to be in a functional vertical column which was determined by the best frequency.Many types of the response area were involved in the neurons of the same penetrations, and an integration mechanism of the frequency was consi derable from the sharp peak type to the flat type through multipeak type.
