The energetics of electric organ discharge generation in gymnotiform weakly electric fish.
Gymnotiform weakly electric fish produce an electric signal to sense their environment and communicate with conspecifics. Although the generation of such relatively large electric signals over an entire lifetime is expected to be energetically costly, supporting evidence to date is equivocal. In this article, we first provide a theoretical analysis of the energy budget underlying signal product...
متن کاملWaveform generation in the weakly electric fish Gymnotus coropinae (Hoedeman): the electric organ and the electric organ discharge.
This article deals with the electric organ and its discharge in Gymnotus coropinae, a representative species of one of the three main clades of the genus. Three regions with bilateral symmetry are described: (1) subopercular (medial and lateral columns of complex shaped electrocytes); (2) abdominal (medial and lateral columns of cuboidal and fusiform electrocytes); and (3) main [four columns, o...
متن کاملNeuromodulation 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...
متن کاملPrecision Measurement of Electric Organ Discharge Timing 4 from Freely Moving Weakly Electric Fish
20 Physiological measurements from an unrestrained, untethered, and freely moving animal 21 permit analyses of neural states correlated to naturalistic behaviors of interest. Precise and 22 reliable remote measurements remain technically challenging due to animal movement, which 23 perturbs the relative geometries between the animal and sensors. Pulse-type electric fish generate 24 a train of d...
