Elasmobranchs Electrophysiology Ram ventilators Unihemispheric sleep Sleep is often a conspicuous behaviour, distinguishable from wakefulness by immobility and postural relaxation, and accompanied by reduced awareness of the local environment. This sleep-related reduced responsiveness can be reversed...

...Idoia Quintana-Urzainqui; Ramón Anadón; Eva Candal; Isabel Rodríguez-Moldes The nervus terminalis (or terminal nerve) system was discovered in an elasmobranch species more than a century ago. Over the past century, it has also been recognized in other vertebrate groups, from agnathans to mammals...

...Barbara E. Wueringer The ampullae of Lorenzini are the electroreceptors of elasmobranchs. Ampullary pores located in the elasmobranch skin are each connected to a gel-filled canal that ends in an ampullary bulb, in which the sensory epithelium is located. Each ampulla functions as an independent...

Cells that were TH+ were located in prominent A1/A2, A6 (locus coeruleus), A9 (substantia nigra), and A10 (ventral tegmental area) cell groups, and in a very small A5 group. We conclude that the variation in chondrichthian...
