Communication is inherently social, so signaling systems should evolve with social systems.
The 'social complexity hypothesis' posits that social complexity necessitates communicative …

The electric sense of electric fish is an alien sense to us for which we have no intuition.
Starting with Hans Lissmann's early studies in the 1950s, step-by-step we have gained more …

Field studies on freely behaving animals commonly require tagging and often are focused
on single species. Weakly electric fish generate a species-and individual-specific electric …

The electric communication signals of weakly electric ghost knifefishes (Gymnotiformes:
Apteronotidae) provide a valuable model system for understanding the evolution and …

When confronted with a highly variable environment, it remains poorly understood how
neural populations encode and classify natural stimuli to give rise to appropriate and …

Since the pioneering work by Moeller, Szabo, and Bullock, weakly electric fish have served
as a valuable model for investigating spatial and social cognitive abilities in a vertebrate …

As communication signal properties change, through genetic drift or selective pressure, the
sensory systems that receive these signals must also adapt to maintain sensitivity and …

Localizing the source of a signal is often as important as deciphering the signal's message.
Localization mechanisms must cope with the challenges of representing the spatial …

The detection and localization of signals relies on arrays of receptors and their spatial
organization plays a key role in setting the accuracy of the system. Electrosensory signals in …

Gymnotiformes are a clade of fishes found throughout Central and South America,
colloquially known as Neotropical electric fishes. They are the so-called “electric fishes” …
