Research Abstract

In the cortex of the rats and cat, parvalbumin (PV) containing GABA inhibitory cells connected each other by gap junction (electric synapses). Thirty to fifty junctions were reported to exist on the dendrites of a PV cell in the cats. In the cortex of the monkey, on the other hand, only several gap junctions were observed on dendrites of each PV cells. PV cells were also known to have basket terminals on the excitatory pyramidal cells. A higher density of PV-containing basket terminals was observed on the pyramidal cells in the primate cortex than in the rodent. In the cortex of the primate, inhibitory cells inhibit the excitatory pyramidal cells stronger than in the cortex of the rodents.
