Electric organ discharges and near-field spatiotemporal patterns of the electromotive force in a sympatric assemblage of Neotropical electric knifefish

Journal of Physiology (Paris), 2016
Descriptions of the head-to-tail electric organ discharge (ht-EOD) waveform – typically recorded with electrodes at a distance of approximately 1–2 body lengths from the center of the subject – have traditionally been used to characterize species ...

Synaptic vesicles isolated from the electric organ of Torpedo californica and from the central nervous system of Mus musculus contain small ribonucleic acids (sRNAs) [PDF]

Genomics Data, 2017
Synaptic vesicles (SVs) are presynaptic organelles that load and release small molecule neurotransmitters at chemical synapses. In addition to classic neurotransmitters, we have demonstrated that SVs isolated from the Peripheral Nervous Systems (PNS) of ...

Fish geometry and electric organ discharge determine functional organization of the electrosensory epithelium. [PDF]

PLoS One, 2011
Active electroreception in Gymnotus omarorum is a sensory modality that perceives the changes that nearby objects cause in a self generated electric field.

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 ...

The myogenic electric organ of Sternopygus macrurus: a non-contractile tissue with a skeletal muscle transcriptome [PDF]

PeerJ, 2016
In most electric fish species, the electric organ (EO) derives from striated muscle cells that suppress many muscle properties. In the gymnotiform Sternopygus macrurus, mature electrocytes, the current-producing cells of the EO, do not contain sarcomeres,

MORPHOLOGICAL CORRELATES OF FUNCTIONAL DIFFERENTIATION OF NODES OF RANVIER ALONG SINGLE FIBERS IN THE NEUROGENIC ELECTRIC ORGAN OF THE KNIFE FISH STERNARCHUS

Journal of Cell Biology, 1972
Electric organs in Sternarchidae are of neural origin, in contrast to electric organs in other fish, which are derived from muscle. The electric organ in Sternarchus is composed of modified axons of spinal neurons.

Elucidation of Rapid Synchronization on Electric Discharge by Use of Model Cell Systems Mimicking Electric Organs of Electric Eel

Electrochemistry
The electric organ of a typical electric fish was artificially constructed by use of a model-cell system combining liquid-membrane cells mimicking the function of K+ and voltage-gated Na+ channels.

Toward model-guided electrophysiology—Encoding of chirps in the electrosensory periphery of Apteronotus leptorhynchus [PDF]

Frontiers in Computational Neuroscience
Models formalize our understanding of a system and generate hypotheses that can be tested experimentally. In this study, we use a previously developed model of p-type electroreceptor afferents to support electrophysiological observations regarding the ...

Electric Eels Wield a Functional Venom Analogue

Toxins, 2021
In this paper, I draw an analogy between the use of electricity by electric eels (Electrophorus electricus) to paralyze prey muscles and the use of venoms that paralyze prey by disrupting the neuromuscular junction.

Influence of Inlet Boundary Conditions on the Prediction of Flow Field and Hemolysis in Blood Pumps Using Large-Eddy Simulation

Bioengineering, 2023
Inlet boundary conditions (BC) are one of the uncertainties which may influence the prediction of flow field and hemolysis in blood pumps. This study investigated the influence of inlet BC, including the length of inlet pipe, type of inlet BC (mass flow ...
