Two Types of Lateral Line Afferents in the Eel (Anguilla anguilla)
Abstract The spontaneous and evoked discharges of eel lateral line sensory organs have been investigated. Each afferent nerve fibre has a well defined punctate receptive field, corresponding to a single canal organ. No axons were found to innervate more than one of these. All afferents pass through...
