Mormyrid fish communicate and navigate using electric organ discharges (EODs). The EOD is highly stereotyped and provides information on sender identity, including species, sex, reproductive condition, and possibly relative status and individual identity. By contrast, the sequence of pulse intervals (SPI) is variable and plays more of a role in signaling behavioral states. Various types of SPI displays may be produced, including tonic patterns such as 'random' and 'regularized', and phasic… Expand
Electrical and behavioral courtship displays in the mormyrid fish Brienomyrus brachyistius
TLDR
It is shown that some SPIs correlate with specific behavioral acts around the time of spawning, and analysis of frequency of occurrences suggests that some SPI patterns are sex and season specific. Expand
Electric organ discharge patterns during group hunting by a mormyrid fish
TLDR
It is shown that EOD accelerations accompany prey probing and size estimation by M. anguilloides, and group members occasionally synchronize bursts of EODs with an extraordinary degree of precision afforded by the mormyrid echo response, suggesting that it may function as a pack cohesion signal.

Central control of electric signaling behavior in the mormyrid Brienomyrus brachyistius: segregation of behavior-specific inputs and the role of modifiable recurrent inhibition
TLDR
The results support the three hypotheses, suggesting that production of different communication behaviors may be regulated by spatially distinct groups of neurons, and recurrent inhibition and disinhibition may play an active role in driving and shaping such behaviors. Expand
From Sequence to Spike to Spark: Evo-devo-neuroethology of Electric Communication in Mormyrid Fishes
TLDR
The mechanisms of electric signal generation, reception, and analysis are reviewed and relate these to the current understanding of the evolution and development of electromotor and electrosensory systems. Expand
Stereotyped temporal patterns in electrical communication
TLDR
Analysis of signal characteristics and their production in relation to several variables suggests that accelerations function as aggressive signals, rasps as male courtship signals, and scallops as advertisement signals in mormyrids. Expand
Electric discharge patterns in group-living weakly electric fish, Mormyrus rume (Mormyridae, Teleostei)
TLDR
This work investigated electrocommunication in a social group of five freely swimming Mormyrus rume during different group behaviours, and found several electrical discharge patterns, which occurred during group foraging, aggressive encounters, fleeing and resting. Expand
Post-natal development of the electromotor system in a pulse gymnotid electric fish
TLDR
The analysis of data from the anatomo-functional study of fish sized between 10 and 300 mm from the species of Gymnotus allowed us to identify three main periods in post-natal development of electrogenesis: before fish reach 55 mm in length, when maturation of neural structures is the main factor determining a characteristic sequence of changes observed in the discharge timing and waveform.

SENSORY SYSTEMS, PERCEPTION, AND LEARNING | Shocking Comments: Electrocommunication in Teleost Fish
TLDR
Tropical freshwater fish in two orders, Gymnotiformes and Mormyriformes, produce weak electric discharges that they use for communication, which serve to communicate about intent during aggression and courtship. Expand
Sensory Specializations of Mormyrid Fish Are Associated with Species Differences in Electric Signal Localization Behavior
TLDR
It is proposed that the distribution of electroreceptors on the body affects the ability of individuals to align parallel to electric field lines and maintain such alignment while approaching the signal source, and visual information may play an important role in localizing signaling individuals in species with small EL and clustered electroreceptorors.

Hormones and Sexual Behavior of Teleost Fishes
TLDR
The role of hormones and neuropeptides in the modulation of fish sexual displays is reviewed and some of the technological developments that promise to increase knowledge in this field in the near future are identified. Expand

Central mechanisms of temporal analysis in the knollenorgan pathway of mormyrid electric fish
TLDR
Of the four known types of electroreceptors in mormyrid fish, theknollenorgan electroreceptor is the one most likely to be involved in the detection of conspecific EOD signals, and recent advances in understanding how the central knollenorgan pathway might be analyzing the temporal structure of the EOD waveform are reviewed.

Ultrastructural features and hormone‐dependent sex differences of mormyrid electric organs
TLDR
The major ultrastructural features of mormyrid electrocytes are described, which include surface invaginations along each face, myonuclei, myofilaments, and neuromuscularlike junctions formed by the axons of spinal electromotoneurons. Expand
Patterns of electric organ discharge activity in the weakly electric fish Brienomyrus niger L. (Mormyridae).
TLDR
The dynamics of the electromotor command system, as reflected by the fish's EOD activity, is compared with that of the well-studied mammalian inferior olive, and mechanisms for a possible self-regulatory central pattern generator are discussed. Expand

TLDR
The organization of electric organs is described for the mormyrid fishes from Africa because each species' particular electrocyte “profile” must underlie the development of species‐specific and hormone‐dependent sex differences in the EOD waveforms. Expand
A temporal analysis of testosterone-induced changes in electric organs and electric organ discharges of mormyrid fishes.
TLDR
The results support the hypothesis that gonadal steroid hormone-induced changes in the EOD are due to structuralChanges in the electrocyte's membranes, and that all of the observed Changes in the discharge of this system can be explained by the action of steroid hormones on the peripheral target cells (electrocytes).

Hormonal control of sex differences in the electric organ discharge (EOD) of mormyrid fishes
TLDR
Field studies have demonstrated that several species of mormyrid fish from Gabon, West Africa have a sex difference in the pulse-like waveform of their Electric Organ Discharge (EOD), suggesting that the response to a steroid hormone may be an indicator of asex difference in a species' EOD waveform.

TLDR
It is shown that testosterone-induced changes in EOD duration are associated with a 2- to 3-fold increase in the duration of action potentials generated by single electrocytes, which emphasize the exquisite interrelationship between steroid hormone action and the cellular machinery determining the electrical properties of single cells that underlie sexually dimorphic and seasonal behaviors.
