Glycogen in the central nervous system of adults and developing anamnia.

The distribution of glycogen in the central nervous system of the viviparous teleost Gambusia affinis and of the oviparous teleost Jordanella floridae during development and in the adults, was examined. It emerged that the glycogen pattern in adults of Gambusia and Jordanella is very similar, whereas there are considerable differences during development. These differences were related to the different ways in which development takes place in the two species.
