The effect of foreign compounds on elasmobranchs and the effect of elasmobranchs on foreign compounds

Comparative Biochemistry and Physiology A, Comparative Physiology, 1972
Abstract 1. 1. Foreign compounds generally exert effects on elasmobranchs that are qualitatively similar to those they exert in mammals. 2. 2. Certain drugs acting on higher centers of the central nervous system produce little effect in the dogfish. 3. 3.

Corticosteroids in plasma of elasmobranchs

Comparative Biochemistry and Physiology Part A: Physiology, 1972
Abstract 1. 1. Free corticosteroids were quantified by double isotope derivative assay in thirteen plasma samples from seven species of elasmobranchs. 2. 2. In each instance, four batoids and three selachians, 1α-hydroxycortico-sterone was the principal plasmatic corticosteroid. 3. 3.

Forebrain Organization in Elasmobranchs

Brain, Behavior and Evolution, 2012
It has long been known that many elasmobranch fishes have relatively large brains. The telencephalon, in particular, has increased in size in several groups, and as a percent of total brain weight, it is as large as in some mammals. Little is known, however, about the organization, connections, and functions of the telencephalon in elasmobranchs. Early

Electrophysiology of the Elasmobranch Stomach

Science, 1959
A consequence of the recent study of the mechanism of gastric secretion has been the presumption, implicit ( 1 ) if not explicit ( 2 ), that the distinctive gastric transmucosal potential has a fundamental role in the formation of hydrochloric acid.
