Electric organ activation in Gymnotus carapo: Spinal origin and peripheral mechanisms

  author={Antonio Caputi and Ana Silva and Omar Macadar},
  journal={Journal of Comparative Physiology A},
A new technique of multiple-air-gap recording was developed to study the EO activation process in Gymnotus carapo. Using this technique, the spatiotemporal pattern of electromotive force generation was investigated in normal and spinal-lesioned animals. Our data indicate that the EOD may be considered as the result of the sequential activation of 3 defined portions of the EO: the abdominal portion (included in the rostral 25% of the fish body), the central portion (comprising the intermediate… CONTINUE READING
