The discrimination and production of temporal patterns on the scale of hundreds of
milliseconds are critical to sensory and motor processing. Indeed, most complex behaviours …

Corollary discharge is an important brain function that allows animals to distinguish external
from self-generated signals, which is critical to sensorimotor coordination. Since discovery of …

Natural selection arising from resource competition and environmental heterogeneity can
drive adaptive radiation. Ecological opportunity facilitates this process, resulting in rapid …

The ability to detect time intervals and temporal patterns is critical to some of the most
fundamental computations the brain performs, including the ability to communicate and …

Brown ghost knifefish, Apteronotus leptorhynchus, are a species of weakly electric fish that
produce a continuous electric organ discharge (EOD) that is used in navigation, prey …

Animals that rely on electrolocation and echolocation for navigation and prey detection
benefit from sensory systems that can operate in the dark, allowing them to exploit sensory …

Weakly electric fish emit and receive low-voltage electric organ discharges (EODs) for
electrolocation and communication. Since the discovery of the electric sense, their …

In the absence of light, the weakly electric fish Gnathonemus petersii detects and
distinguishes objects in the environment through active electrolocation. In order to test which …

Selection (1859), Darwin paid special attention to difficulties with his theory, devoting an
entire chapter to the subject. The evolution of electrogenesis was one such area of concern …

A large brain can offer several cognitive advantages. However, brain tissue has an
especially high metabolic rate. Thus, evolving an enlarged brain requires either a decrease …
