Abstract

Platypus mucous gland electroreceptors differ from electroreceptors described for fish in that they lack an associated specialized sensory cell. Thus a bare nerve terminal is used to detect electrical stimuli, and also to generate local and action potentials. Previous studies have identified these terminals (an average of 16 per mucous gland), but had not shown whether the terminals have direct contact with the duct of the mucous gland. This poses the problem of how the electrical stimulus reaches the nerve terminals. This study demonstrates the portions of the nerve terminals responsible for electroreception, and shows how these portions use the surrounding epidermal tissue to overcome the ..
