Karyometric development of four topographic subdivisions of the paraventricular nucleus in normal and castrated mice

Abstract

A karyometric study of the spontaneous development of four topographic subdivisions in the paraventricular nucleus was made in male albino mice from the 5th to the 190th day of postnatal life. Anoter 25 animals were castrated at 20 days and examined at 25, 35, 45, 55 and 85 days of life. A comparison was established between both groups of mice.
