Comparison of calbindin D 28K and cytochrome c oxidase in electrosensory nuclei of high- and low-frequency weakly electric fish (Gymnotiformes)

Weakly electric fish (Gymnotiformes) emit quasi-sinusoidal electric organ discharges within speciesspecific frequency ranges. The electrosensory system is organized into 2 parallel pathways which convey either the amplitude or the timing of each electric organ discharge cycle. Two putative metabolic activity markers, calbindin D 28K and cytochrome c oxidase, and their relationship with the electrosensory nuclei of high- and low-frequency …
