... of the gymnotiform electric fish Sternopygus macrurus to trans-differentiate into electrocytes, the non-contractile electrogenic cells of the electric organ (EO), to investigate the mechanisms that regulate the skeletal muscle phenotype. In S. macrurus , mature electrocytes possess a phenotype that is intermediate...

... waveforms: (1) electrocyte geometry and channel repertoire; (2) the localization of synaptic contacts on electrocyte surfaces; and (3) electric activity of electromotor axons preceding the discharge of electrocytes. At the organismic level, three factors determine the integration of the EOD as a behavioral...

... (V 5 ). We found that: (a) the innervation pattern of the electrocytes, (b) the three earlier, neurally driven, EOD components (V 1 to V 3 ), and(c) their remnants after curarisation were almost identical in the two taxa. The equivalent electromotive forces of late components (V 4 and V 5 ) increased...
