[Quantitative characteristics of neuronal composition of the ventral part of the cat's medial geniculate body].

Abstract

Calculation of numerical density of neurons in ventral part of cat's medial geniculate body (vMGB) was made. It was shown that 1 mm3 of vMGB tissue contains 29,460 neurons. After 6 months from unilateral removal of the auditory cortex the quantity of large (supposedly thalamocortical) neurons in ipsilateral vMGB reduced on average by 78.1%, but of small ones--only by 10.7%.
