Multiple electrosensory maps in the medulla of weakly electric gymnotiform fish. II. Anatomical differences.

Both wave- and pulse-type species of weakly electric gymnotiform fish have 3 topographic maps of electroreceptive information in the electrosensory lateral line lobe (ELL). These maps receive identical input from trifurcating axons of phase- and amplitude-coding primary afferents (Carr et al., 1982; Heiligenberg and Dye, 1982). Physiological experiments in the ELL of the wave-type fish Eigenman...

Multiple electrosensory maps in the medulla of weakly electric gymnotiform fish. I. Physiological differences.

The electrosensory lateral line lobe in the weakly electric gymnotiform fish Eigenmannia contains 3 topographic maps of high-frequency (tuberous) electroreceptive information from the body surface. The maps receive identical primary afferent input since axonal collaterals of both amplitude- and phase-coding afferents project to all 3 maps (Heiligenberg and Dye, 1982). Response properties of the...

Neuromodulation of early electrosensory processing in gymnotiform weakly electric fish.

Sensory neurons continually adapt their processing properties in response to changes in the sensory environment or the brain's internal state. Neuromodulators are thought to mediate such adaptation through a variety of receptors and their action has been implicated in processes such as attention, learning and memory, aggression, reproductive behaviour and state-dependent mechanisms. Here, we re...

Burst Firing in the Electrosensory System of Gymnotiform Weakly Electric Fish: Mechanisms and Functional Roles

Neurons across sensory systems and organisms often display complex patterns of action potentials in response to sensory input. One example of such a pattern is the tendency of neurons to fire packets of action potentials (i.e., a burst) followed by quiescence. While it is well known that multiple mechanisms can generate bursts of action potentials at both the single-neuron and the network level...
