The morpho-quantitative analysis carried out in the neuronal population of the periaqueductal gray matter of the cat showed that nuclear inclusions were mainly of the filamentous type and that they were distributed predominantly in the external region, i.e., in the part of the periaqueductal gray matter situated furthest from the cerebral aqueduct, where 30% of the cells contain nuclear inclusions. In the internal region, i.e., in the part nearest the subependymal zone, only 2% of the neurons had nuclear inclusions. The glia in the internal region was more abundant and surrounded each nerve cell body while in the external zone of the periaqueductal gray matter it was scanty and did not delimit the neuronal soma. There may be a relationship between the incidence of nuclear inclusions and the neuron/glia ratio.
