Influence of water temperature on the electric organ discharge (EOD) of the weakly electric fish Marcusenius cyprinoides (Mormyridae).
1. The influence of different water temperatures on the electric organ discharge (EOD) of a mormyrid fish Marcusenius cyprinoïdes was studied. The range of the water temperatures was fixed according to the seasonal temperature variations of the rivers in Central Africa, the natural habitat of this species. 2. The EOD activity was characterized using the following parameters: mean EOD rate, EOD ...
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 کاملElectrolocation with an electric organ discharge waveform for biomimetic application
Weakly electric fish use electric organ discharge (EOD) and their electroreceptors to identify prey, explore their surroundings, and communicate with other members of the same species. They are specialized in active electrolocation using a self-generated electric field, and they can sense distortion of their self-generated electric field caused by a target object. Electric fish have many electr...
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...
