...Brandon Neeley; Tyler Overholt; Emily Artz; Steven G. Kinsey; Gary Marsat Cannabinoid (CB) receptors are widespread in the nervous system and influence a variety of behaviors. Weakly electric fish have been a useful model system in the study of the neural basis of behavior, but we know nothing...

...Da-Wei Liu; Ying Lu; Hong Young Yan; Harold H. Zakon Losses of cone opsin genes are noted in animals that are nocturnal or rely on senses other than vision. We investigated the cone opsin repertoire of night-active South American weakly electric fish. We obtained opsin gene sequences from genomic...

... his experiments. In 1838, Faraday extended von Humboldt's experiments to observe an eel-generated spark, confirming the electrical nature of the eel's discharge [Faraday, 1838]. Electric eels and other strongly electric fish were thus useful for our early understanding of electricity [Williamson...

There are many small fishes and small-eyed fishes (e.g. electric fishes) adapted to various ecological niches. In addition, the morphology and function of the visual system are required to be tuned...

To quantify cell proliferation along the length of the spinal cord, fish were given a single bromodeoxyuridine (BrdU) injection immediately after spinal transection or sham surgery. Spinal transection significantly increased the density of BrdU + cells...

...Carl D. Hopkins; Nathaniel C. Comfort; Joseph Bastian; Andrew H. Bass Hypopomus pinnicaudatus, an electric fish, has a marked sexual dimorphism in its tail filament. Sexually mature males have long, 'feathered' tails as compared with females. The sexual dimorphism emerges when a fish reaches about...
