title: An electrophysiological investigation of the projection of the intramedullary primary afferent cells of the lamprey ammocoete.
abstract: The intramedullary dorsal cells, whose peripheral processes form primary afferents, were identified in the lamprey ammocoete and were antidromically invaded by stimulation of their rostrally projecting intraneuraxial axons. Twenty-five out of 33 cells were found to project to the isthmus; conduction velocity was found to decrease in a rostral direction, suggesting that numerous collateral branches are given off as the axon ascends through the cord and brain stem.
