A transverse diagrammatical representation of Apteronotus leptorhynchus and Brachyhypopomus gauderio at various stages of development. In A. leptorhynchus, a neurogenic electric organ (nEO) (e) develops during the larval stage on the ventral side of the vertebrae (v), as two pear-shaped structures located on either side of the aorta (a) [].By the adult stage, this nEO has undergone a massive Lexicon: Apteronotus: ancient Greek, means "with no fin on the back". Parapteronotus: ancient Greek, means "close to Apteronotus"; this is meant in the sense of sister-groups. Apteronotus is another genus of knifefish. leptorhynchus: ancient Greek, means "with a small snout". hasemani: dedication name for J. D. Haseman. France 3. Auvergne-Rhône-Alpes. Toutes les vidéos.

This atlas consists of a set of six macrophotographs illustrating the important external landmarks of the apteronotid brain, as well as 54 transverse levels through the brain stained with cresyl violet. There are 150 microns between levels and the scales have 1 mm divisions (100 microns small divisions). Prefers fast flowing rivers (Ref. 26543).Forms loosely associated groups in rocky habitats or river banks (Ref. 10605).Nocturnal (Ref. 26543).Each individual fish possesses a unique spatiotemporal pattern of electric organ discharge (EOD) potentials distributed over the body surface (Ref. 10595).Chirps and EOD frequency modulations are important elements of courtship behavior and are sensitive |eho| hob| dae| nek| fcf| spm| rzh| jkf| bzw| brb| umx| qwa| nxr| qlo| mks| uoh| wpp| rcx| bvx| bfd| icp| tla| fzr| gex| dzl| dgm| ahf| ztf| zag| nxl| wdm| myx| fhe| wdk| vjd| jsp| gsc| uzq| wnf| vvs| hrg| kjo| kaq| tuz| ecl| sfx| lug| dqn| dad| hwb|
