Abstract(in English) We constructed a functional scheme of macaque auditory by distribution of Calcium Binding Proteins, Parvalbumin (PV), Calbindin (CB), and Calretinin (CR). Auditory cortex is consisted of one core (primary cortex), and five surrounding rings, which correspond with secondary, tertiary, quaric, and quintic cortices. Parvabumin showed a graduation, that is, inner core is most PV-rich, and outer rings showed the decrease of PVconcentration. For CB and CR, the graduation pattern is opposite from that of PV. These six levels are connected by feed-forward and feed-back projections. And by these three GABAnergic inhibitory neurons, auditory cortex may contain both integrative and diffrential circuit in it.
