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 ...

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.

The transcriptional correlates of divergent electric organ discharges in Paramormyrops electric fish [PDF]
BMC Evolutionary Biology, 2020 Abstract Background Understanding 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 genus

eLife, 2022 Brain region size generally scales allometrically with brain size, but mosaic shifts in brain region size independent of brain size have been found in several lineages and may be related to the evolution of behavioral novelty.

Electric organ discharges and electric images during electrolocation [PDF]
Journal of Experimental Biology, 1999 ABSTRACT Weakly electric fish use active electrolocation – the generation and detection of electric currents – to explore their surroundings. Although electrosensory systems include some of the most extensively understood circuits in the vertebrate central nervous system, relatively little is known quantitatively about how fish ...

Electric imaging through evolution, a modeling study of commonalities and differences. [PDF]
PLoS Computational Biology, 2014 Modeling the electric field and images in electric fish contributes to a better understanding of the pre-receptor conditioning of electric images. Although the boundary element method has been very successful for calculating images and fields, complex ...

A new and improved electric fish finder with resources for printed circuit board fabrication [PDF]
Neotropical Ichthyology, 2019 We describe the circuit design, construction, and operation of a field-portable electric fish finder (an AC-coupled wide-band differential bio-amplifier with loudspeaker output).

A Spark in the Dark: Uncovering Natural Activity Patterns of Mormyrid Weakly Electric Fish
Frontiers in Ecology and Evolution, 2022 To understand animal ecology, observation of wildlife in the natural habitat is essential, but particularly challenging in the underwater realm. Weakly electric fishes provide an excellent opportunity to overcome some of these challenges because they ...
