Theoretical analysis of pre-receptor image conditioning in weakly electric fish. [PDF]

open access: yesPLoS Computational Biology, 2005
Electroreceptive fish detect nearby objects by processing the information contained in the pattern of electric currents through the skin. The distribution of local transepidermal voltage or current density on the sensory surface of the fish's skin is the

Magic trait Electric Organ Discharge (EOD) Dual function of electric signals promotes speciation in African weakly electric fish

open access: yesCommunicative & Integrative Biology, 2009
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

Predation and Crypsis in the Evolution of Electric Signaling in Weakly Electric Fishes

open access: yesFrontiers in Ecology and Evolution, 2019
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.

Automatic realistic real time stimulation/recording in weakly electric fish: long time behavior characterization in freely swimming fish and stimuli discrimination. [PDF]

open access: yesPLoS ONE, 2014
Weakly electric fish are unique model systems in neuroethology, that allow experimentalists to non-invasively, access, central nervous system generated spatio-temporal electric patterns of pulses with roles in at least 2 complex and incompletely ...

Feedback Control as a Framework for Understanding Tradeoffs in Biology [PDF]

open access: yes, 2014
Control theory arose from a need to control synthetic systems. From regulating steam engines to tuning radios to devices capable of autonomous movement, it provided a formal mathematical basis for understanding the role of feedback in the stability (or ...

Species recognition by the sequence of discharge intervals in weakly electric fishes of the genus Campylomormyrus (Mormyridae, Teleostei) [PDF]

open access: yes, 1994
In two Campylomormyrus species, tamandua and rhynchophorus from Central Africa, the electric organ discharge (EOD) activity was studied during the nocturnal activity phase in the laboratory. Both species have a pulse-type EOD of less than 200 μs duration

Investigation of a Bubble Detector based on Active Electrolocation of Weakly Electric Fish [PDF]

open access: yes, 2013
Weakly electric fish employ active electrolocation for navigation and object detection. They emit an electric signal with their electric organ in the tail and sense the electric field with electroreceptors that are distributed over their skin. We adopted

A Spark in the Dark: Uncovering Natural Activity Patterns of Mormyrid Weakly Electric Fish

open access: yesFrontiers in Ecology and Evolution, 2022
To understand animal ecology, observation of wildlife in the natural habitat is essential, but particularly challenging in the underwater realm. Weakly electric fishes provide an excellent opportunity to overcome some of these challenges because they ...

Separability of drag and thrust in undulatory animals and machines [PDF]

open access: yes, 2014
For nearly a century, researchers have tried to understand the swimming of aquatic animals in terms of a balance between the forward thrust from swimming movements and drag on the body.
