Quantitative analysis of neuron-glial relationships in the buccal ganglion of Planorbis: life constancy in the absence of changes in functional output.
The numbers and volumes of the neurons and glial cells in the buccal ganglia of Planorbis were analyzed by a new technique (computer image analysis of serial-section autoradiograms). The nerve-glia relationship are remarkably constant in the ganglia throughout the adult life of the animal (4-5 years), which correlates with their unchanging functional output to control the feeding cycle of the animal.
