Laminar Organization and Neuronal Diversity in Temporal Region of Indian Gray Mongoose

Abstract

Temporal lobe is known to perform vital role in visual discrimination and identification of objects. Cresyl violet and Golgi studies of temporal region of Indian gray mongoose revealed diversity of neurons dispersed in six layers of the region. Pyramidal neurons were observed to outnumber the other four types of neurons in the temporal region supporting the specialization of this brain region as compared to primitive brains of monotremes and insectivores. Moreover, specialization of neurons provides better functioning and refining learning and predatory behavior of the animal.
