Sensitivity of Purkinje cell dendrites to glutamic acid.

The distribution of glutamate sensitive site was studied in vitro in thin cerebellar sections from guinea-pigs, in which Purkinje cell bodies and some of the principal dendrites were identified microscopically. Glutamate administered near the cell body induced firing. Stronger excitation, however, was produced when glutamate was administered to the molecular layer along a strip of tissue extending from the soma of the cell under study towards the pial surface of the slice. Excitation induced by glutamate slowly declined in some cells during prolonged administration. D-Glutamate was a weaker excitant than the L-isomer. These results suggest that the dendrite of the Purkinje cell is more sensitive to glutamate that the cell soma.
