This book provides a comparative perspective on the topic of electroreception and reviews some of the fundamental insights gained from studies of electrosensory and electromotor systems to understand how the nervous system extracts biologically relevant information from the natural environment A Brief History of Electrogenesis and Electroreception in Fishes Bruce A. Carlson and Joseph A. Sisneros The Development and Evolution of Lateral Line Electroreceptors: Insights from Comparative Molecular Approaches Clare V. H. Baker Electrosensory Transduction: Comparisons Across Structure, Afferent Response Properties, and Cellular Physiology Duncan B.
