Waveform generation in the weakly electric fishGymnotus coropinae(Hoedeman): the electric organ and the electric organ discharge [PDF]
Journal of Experimental Biology, 2009 SUMMARYThis article deals with the electric organ and its discharge in Gymnotus coropinae, a representative species of one of the three main clades of the genus. Three regions with bilateral symmetry are described: (1)subopercular (medial and lateral columns of complex shaped electrocytes); (2)abdominal (medial and lateral columns of cuboidal and ...

Two new species and a new subgenus of toothed Brachyhypopomus electric knifefishes (Gymnotiformes, Hypopomidae) from the central Amazon and considerations pertaining to the evolution of a monophasic electric organ discharge [PDF]
ZooKeys, 2013 We describe two new, closely related species of toothed Brachyhypopomus (Hypopomidae: Gymnotiformes: Teleostei) from the central Amazon basin and create a new subgenus for them.

Plasticity of electric organ discharge waveform in the South African Bulldog fish,
Frontiers in Zoology, 2008 Background In adult male Marcusenius pongolensis the duration of their Electric Organ Discharge (EOD) pulses increases with body size over lifetime (267 to 818 μs, field-measured).

Patterns of the electric organ discharge during courtship and spawning in the mormyrid fish, Pollimyrus isidori [PDF]
Behavioral Ecology and Sociobiology, 1989 Pollimyrus isidori's electric organ discharge (EOD) is of the pulse type. Patterns of EOD intervals were investigated prior to, during and following spawning behaviors as related with overt behaviors, and with the sound production by the nestbuilding ...

The electrogenicity of the Na+/K+-ATPase poses challenges for computation in highly active spiking cells [PDF]
eLifeThe evolution of the Na+/K+-ATPase laid the foundation for ion homeostasis and electrical signaling. While not required for restoration of ionic gradients, the electrogenicity of the pump (resulting from its 3:2 stoichiometry) is useful to prevent ...

The transcriptional correlates of divergent electric organ discharges in Paramormyrops electric fish [PDF]
, 2019 AbstractBackgroundUnderstanding the genomic basis of phenotypic diversity can be greatly facilitated by examining adaptive radiations with hypervariable traits. In this study, we focus on a rapidly diverged species group of mormyrid electric fish in the genusParamormyrops, which are characterized by extensive phenotypic variation in electric organ ...

A rare case report of gallbladder perforation caused by trauma [PDF]
Frontiers in MedicineIsolated gallbladder perforation in blunt trauma is rare, accounting for approximately 2% of abdominal trauma laparotomy patients, often leads to delayed diagnosis due to non-specific symptoms.
