Collective sensing in electric fish. [PDF]
Nature, 2023 A number of organisms, including dolphins, bats, and electric fish, possess sophisticated active sensory systems that use self-generated signals (e.g. acoustic or electrical emissions) to probe the environment1,2. Studies of active sensing in social groups have typically focused on strategies for minimizing interference from conspecific emissions2-4 ...

A History of Corollary Discharge: Contributions of Mormyrid Weakly Electric Fish. [PDF]
Front Integr Neurosci, 2020 Corollary discharge is an important brain function that allows animals to distinguish external from self-generated signals, which is critical to sensorimotor coordination.

Divergent cis-regulatory evolution underlies the convergent loss of sodium channel expression in electric fish. [PDF]
Sci Adv, 2022 South American and African weakly electric fish independently evolved electric organs from muscle. In both groups, a voltage-gated sodium channel gene independently lost expression from muscle and gained it in the electric organ, allowing the channel to ...

An Electric Fish-Based Arithmetic Optimization Algorithm for Feature Selection. [PDF]
Entropy (Basel), 2021 With the widespread use of intelligent information systems, a massive amount of data with lots of irrelevant, noisy, and redundant features are collected; moreover, many features should be handled.

Advances in non-invasive tracking of wave-type electric fish in natural and laboratory settings. [PDF]
Front Integr Neurosci, 2022 Recent technological advances greatly improved the possibility to study freely behaving animals in natural conditions. However, many systems still rely on animal-mounted devices, which can already bias behavioral observations.

Electric signal synchronization as a behavioural strategy to generate social attention in small groups of mormyrid weakly electric fish and a mobile fish robot. [PDF]
Biol Cybern, 2021 African weakly electric fish communicate at night by constantly emitting and perceiving brief electrical signals (electric organ discharges, EOD) at variable inter-discharge intervals (IDI).

Omnidirectional Electric Fish [PDF]
PLoS Biology, 2007 What could an African lion stalking a distant impala in the African savanna possibly have in common with an electric fish searching for nearby water fleas in the Amazon River? Both the lion and the rather less daunting 14-cm black ghost knifefish (Apteronotus albifrons) use sensory information to help them to locate and catch prey.
