A method for extirpation of the pineal gand in albino rats

Abstract

A method for extirpation of the pineal gland in albino rats and other rodents (e. g., ground squirrels) is proposed. Epiphysectomy is carried out by resection of a fragment of the bone with the underlying pineal gland. Using this method, many animals can be operated within a short period; the method is reliable and simple, which recommends it for chronobiological studies.
