The functioning of the lateral-line systems of fishes and amphibians as water displacement detectors is revealed by a number of behavioral studies dealing with prey localisation, escape reactions and schooling behavior (Dijkgraaf, 1962; Schwartz, 1974; Russell, 1976; Partridge and Pitcher, 1980). Most recently, the ability to discriminate between stationary objects using the lateral-line system, has been reported for the blind cave fish, Anoptichthys jordani (Weissert and v. Campenhausen, 1981). But how information from the receptor level causes the orienting reactions is largely unknown. A possible approach to investigate signal processing in the lateral-line system is to analyse the transmission from the primary afferent level to higher-order neurons. This, however, needs a detailed knowledge of the organization of lateral-line receptor organs, the neuromasts.
