The wide variety of animal behaviours that can be observed today arose through the
evolution of their underlying neural circuits. Advances in understanding the mechanisms …

The electric organ discharges (EODs) produced by weakly electric fish have long been a
source of scientific intrigue and inspiration. The study of these species has contributed to our …

A number of organisms, including dolphins, bats and electric fish, possess sophisticated
active sensory systems that use self-generated signals (for example, acoustic or electrical …

Several studies have begun to elucidate the genetic and developmental processes
underlying major vertebrate traits. Few of these traits have evolved repeatedly in vertebrates …

How neural networks evolved to generate the diversity of species-specific communication
signals is unknown. For receivers of the signals, one hypothesis is that novel recognition …

The Amazon has the highest richness of freshwater organisms in the world, which has led to
a multitude of hypotheses on the mechanisms that generated this biodiversity. However …

Apteronotidae and Mormyridae are species-rich clades of weakly electric fishes from
Neotropical and Afrotropical freshwaters, respectively, known for their high morphological …

Electric fish have served as a model system in biology since the 18th century, providing
deep insight into the nature of bioelectrogenesis, the molecular structure of the synapse, and …

Voltage-gated sodium channels, Nav1, play a crucial role in the generation and propagation
of action potentials and substantially contribute to the shape of their rising phase. The …

Sensory systems play a key role in social behavior by mediating the detection and analysis
of communication signals. In mormyrid fishes, electric signals are processed within a …
