Diurnal Changes in the Topographical Distribution of Glycogen in the Brain of Iguana iguana

Abstract

RECENTLY I investigated the topographical distribution of glycogen in the brain of Iguana iguana in relation to the environmental temperature, and in animals with glycogen-accumulation disease1. It appeared that a decrease in environmental temperature results sometimes in a decrease in concentration of the glycogen in the brain tissue, and in some cases an increase, for in animals with heptomegalia glycogenica the glycogen concentration in the tissue of the cortex cerebri, the diencephalon, the mesencephalon, the cerebellum and the medulla oblongata increases significantly.
