Abstract
Summary: Activity of efferent fibers was recorded from the ramus ophthalmicus superficialis of the head lateral line nerve and the ramus medialis of the trunk lateral line nerve of the axolotl Ambystoma mexicanum. Baseline activity and activity evoked by sensory stimuli were examined. Electrical stimulation of selected branches was used to determine the conduction velocity and the branching pattern of efferent fibers. The influence of lesions at different levels in the CNS on efferent activity was studied. Up to 5 units with baseline activity were found in a single ramus of the lateral line nerve. Discharge rates were variable and highly irregular; they differed between units of the same branch. Bursting activity occurred in 62% of the units. Movements of the animal were accompanied by activity in up to 8 efferent units in a single nerve. Efferent activity could be elicited or modified by stimulation of visual, labyrinthine, somatosensory, and lateral line systems. Stimulation of the electrosensory system had no effect. Individual efferent neurons innervated different fields in the lateral line periphery. Conduction velocities of efferent fibers ranged from 5 to 12 m/s. Efferent units received input from various sources at different brain levels up to the diencephalon. These in puts determined the baseline activity. The mechanosensory input was mediated at the medullary level.
