A unique evolutionary specialization of African weakly electric fish (Mormyridae) is their ability to produce and perceive electric signals. Mormyrids use their Electric Organs Discharge (EOD) for electrolocation and electrocommunication. Here we discuss

Effects of hypoxia on swimming and sensing in a weakly electric fish
Low dissolved oxygen (hypoxia) can severely limit fish performance, especially aerobically expensive behaviours including swimming and acquisition of sensory information.

Evaluation of neural activity during natural behaviours is essential for understanding how the brain works. Here we show that neuron-specific self-evoked firing patterns are modulated by an object’s presence, at the electrosensory lobe neurons of ...

Synthesis of an electric sensor based control for underwater multi-agents navigation in a file [PDF]
International audienceThanks to an electro-sensible skin, some species of fish can feel the surrounding electric field generated by them-self or other fish.

Shape recognition and classification in electro-sensing
This paper aims at advancing the field of electro-sensing. It exhibits the physical mechanism underlying shape perception for weakly electric fish. These fish orient themselves at night in complete darkness by employing their active electrolocation ...

Sexual signals in electric fishes [PDF]
Electroreceptive bony fishes of Africa (the Mormyriformes) and South America (the Gymnotiformes) detect and communicate with conspecifics by their continuously discharging electric organs. Laboratory studies of members of each group are beginning to reveal the mechanisms of communicating with and finding mates, offering much scope for future studies of

Active sensing associated with spatial learning reveals memory-based attention in an electric fish.
Active sensing behaviors reveal what an animal is attending to and how it changes with learning. Gymnotus sp, a gymnotiform weakly electric fish, generates an electric organ discharge (EOD) as discrete pulses to actively sense its surroundings.

Neural representations of behaviorally relevant stimulus features displaying invariance with respect to different contexts are essential for perception. However, the mechanisms mediating their emergence and subsequent refinement remain poorly understood ...

Predation and Crypsis in the Evolution of Electric Signaling in Weakly Electric Fishes
Eavesdropping by electroreceptive predators poses a conflict for weakly electric fish, which depend on their Electric Organ Discharge (EOD) signals both for navigation and communication in the dark.

Modeling the electric field of weakly electric fish [PDF]
SUMMARYWeakly electric fish characterize the environment in which they live by sensing distortions in their self-generated electric field. These distortions result in electric images forming across their skin. In order to better understand electric field generation and image formation in one particular species of electric fish, Apteronotus ...
