Morphological and electrophysiological properties of the electromotoneurones of the electric ray Torpedo marmorata in vivo and in in vitro brain slices.
The morphology of the adult electromotoneurones of the electric ray Torpedo marmorata has been investigated by intracellular injection of horseradish peroxidase. The results show particularly small dendritic fields, poor dendritic branching, and the existence of two distinct types of dendrites. The electrophysiological data demonstrate that the electromotoneurones behave similarly in vivo and in in vitro brain slices. Observations on spontaneous and stimulus-evoked postsynaptic potentials suggest quantal release of transmitter in the Torpedo central nervous system.
