Patterns of Electrical Communication Among Gymnotoid Fish
… hiding places selected, while others generalize. Eigenmannia virescens and Sternopygus macrurus select a wide range of hiding places, but Sternopygus individuals are randomly dispersed whereas Eigenmannia tend to clump together. The breeding season of most gymnotids starts with a migration into a …

Multisensory integration in weakly electric fish
… to two categories of electrosensory stimuli in Eigenmannia virescens were studied. The first category of stimulus is electrical signals with frequencies below 50 Hz that are encoded in the activity of ampullary receptors. The second category is amplitude modulations of the electric organ …

Electric Organ Discharge Frequency Modulations Evoked in Response to Jamming Stimuli in the Weakly Electric Brown Ghost Knifefish (Apteronotus Leptorynchus)
… studied in two genera of electric fish (Eigenmannia and Apteronotus) using a frequency clamp stimulus regime. Frequency clamped stimuli are electronically controlled to maintain a specific frequency difference (DF) between the animal’s EOD frequency and the frequency of the jamming signal …
