Plasticity varies with boldness in a weakly-electric fish. [PDF]
Front Zool, 2016 The expression of animal personality is indicated by patterns of consistency in individual behaviour. Often, the differences exhibited between individuals are consistent across situations. However, between some situations, this can be biased by variable levels of individual plasticity.

Dynamics of a neuronal pacemaker in the weakly electric fish Apteronotus. [PDF]
Sci Rep, 2020 Abstract The precise timing of neuronal activity is critical for normal brain function. In weakly electric fish, the medullary pacemaker network (PN) sets the timing for an oscillating electric organ discharge (EOD) used for electric sensing. This network is the most precise biological oscillator known, with sub-microsecond variation in

Delay-Dependent Response in Weakly Electric Fish under Closed-Loop Pulse Stimulation. [PDF]
PLoS ONE, 2015 In this paper, we apply a real time activity-dependent protocol to study how freely swimming weakly electric fish produce and process the timing of their own electric signals. Specifically, we address this study in the elephant fish, Gnathonemus petersii,

Social interactions between live and artificial weakly electric fish: Electrocommunication and locomotor behavior of Mormyrus rume proboscirostris towards a mobile dummy fish. [PDF]
PLoS ONE, 2017 Mormyrid weakly electric fish produce short, pulse-type electric organ discharges for actively probing their environment and to communicate with conspecifics.

Spatial acuity and prey detection in weakly electric fish.
PLoS Computational Biology, 2007 It is well-known that weakly electric fish can exhibit extreme temporal acuity at the behavioral level, discriminating time intervals in the submicrosecond range. However, relatively little is known about the spatial acuity of the electrosense.

Neural correlations enable invariant coding and perception of natural stimuli in weakly electric fish [PDF]
eLife, 2016 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 ...

Electric pulse characteristics can enable species recognition in African weakly electric fish species [PDF]
Scientific Reports, 2018 Communication is key to a wide variety of animal behaviours and multiple modalities are often involved in this exchange of information from sender to receiver.

Daily changes in the electric behavior of weakly electric fish naturally persist in constant darkness and are socially synchronized [PDF]
Biology Open, 2018 Daily rhythms allow anticipation of changes and allocation of energy to better cope with predictable events. Rhythms in behavior result from a complex combination of physiological processes timed by the nervous system and synchronized with external ...

Electrocommunication for weakly electric fish
Inverse Problems and Imaging, 2020 This paper addresses the problem of the electro-communication for weakly electric fish. In particular we aim at sheding light on how the fish circumvent the jamming issue for both electro-communication and active electro-sensing. A real-time tracking algorithm is presented.
