Waveform 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 کاملThe 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 کاملModeling the electric field of weakly electric fish.
Weakly electric fish characterize the environment in which they live by sensing distortions in their self-generated electric field. These distortions result in electric images forming across their skin. In order to better understand electric field generation and image formation in one particular species of electric fish, Apteronotus leptorhynchus, we have developed three different numerical mod...

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...
