Cutaneous electrical oscillation in a weakly electric fish, Gymnarchus niloticus
Journal of Comparative Physiology A: Sensory, Neural, and Behavioral Physiology, 2001An African electric fish, Gymnarchus niloticus. ceases its electric organ discharge for a prolonged time in response to external electrical signals. During the cessation of electric organ discharges from the electric organ, a weak sinusoidal signal (approximately 0.1 mV cm(-1)) near the fish's previous discharge frequency was recorded near the body ...

Neural maps in the electrosensory system of weakly electric fish
Current Opinion in Neurobiology, 2014The active electrosense of weakly electric fish is evolutionarily and developmentally related to passive electrosensation and the lateral line system. It shows the most highly differentiated topographic maps of the receptor array of all these senses.

The Electric Image in Weakly Electric Fish: Perception of Objects of Complex Impedance
Journal of Experimental Biology, 2000ABSTRACT Weakly electric fish explore the environment using electrolocation. They produce an electric field that is detected by cutaneous electroreceptors; external objects distort the field, thus generating an electric image. The electric image of objects of complex impedance was investigated using a realistic model, which was able to ...

Electric images of two low resistance objects in weakly electric fish
Biosystems, 2003Electroreceptive fish detect nearby objects by processing the information contained in the pattern of electric currents through their skin. In weakly electric fish, these currents arise from a self-generated field (the electric organ discharge), depending on the electrical properties of the surrounding medium.

Sensorimotor adaptation to destabilizing dynamics in weakly electric fish
Current BiologyHumans and other animals can readily learn to compensate for changes in the dynamics of movement. Such changes can result from an injury or changes in the weight of carried objects. These changes in dynamics can lead not only to reduced performance but also to dramatic instabilities.

Active Electroreception in Weakly Electric Fish
2017Abstract American gymnotiformes and African mormyriformes have evolved an active sensory system using a self-generated electric field as a carrier of signals. Objects polarized by the discharge of a specialized electric organ project their images on the skin where electroreceptors tuned to the time course of the self-generated field ...
