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

Animal communication plays an essential role in triggering diverse behaviors. It is believed
in this regard that signal production by a sender and its perception by a receiver is co …

Glass knifefish (Eigenmannia) are a group of weakly electric fishes found throughout the
Amazon basin. Their electric organ discharges (EODs) are energetically costly adaptations …

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 …

Signal analysis plays a preeminent role in neuroethological research. Traditionally, signal
identification has been based on pre-defined signal (sub-) types, thus being subject to the …

Localizing the source of a signal requires sophisticated neural mechanisms and we are still
uncovering the coding principles that support accurate spatial processing. Weakly electric …

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 …

The identity of sensory stimuli is encoded in the spatio-temporal patterns of responses of the
encoding neural population. For stimuli to be discriminated reliably, differences in …
