... firing neurons in the electromotor and electrosensory systems of Apteronotus leptorhynchus [Turner and Moroz, 1995]. These findings suggested that nitric oxide synthase (NOS) is expressed in these neurons and may regulate their precise, high frequency firing. We extended these results by examining...

...K.D. Dunlap; G.T. Smith; A. Yekta Weakly electric fish emit an electric communication signal that is controlled by a highly specialized neural circuit. In Apteronotus, the continuous electric organ discharge (EOD) is generated by electrotonically coupled neurons in the hindbrain pacemaker nucleus...

... and their propensity to produce aggressive communication signals called ‘chirps’. Brown ghost (Apteronotus leptorhynchus) males produce high frequency EODs while females produce low frequency EODs. When presented with an EOD mimic, males chirp frequently, while females seldom chirp. By contrast, black ghost...
