Feeding-Entrained Circadian Rhythms in Fishes,xtensive work with laboratory mammals, however, information on this topic in fishes is meager. An attempt at a broad overview at this point is fated from the outset to be data poor and speculation rich; hopefully this paper will, nevertheless, serve a heuristic role. Specifically, the paper addresse

Regulation of the Rhythmic Melatonin Secretion by Fish Pineal Photoreceptor Cells,resent major components in the adaptation of organisms to their environment. Environmental factors, such as light and temperature, play an important role in the synchronization of these rhythms. In vertebrates, synchronization is mediated through the circadian system, which is composed of sensors an

Melatonin Synthesis by the Teleost Pineal: An Overview,for specific reasons, melatonin formation in teleost pineal organs, should be asked to prepare an overview of the mechanisms that seem to govern and control melatonin synthesis. One examines melatonin formation as it is associated with electrical properties of teleost pineal photoreceptor cells, ano

External stimuli from the environment are responsible for the entrainment or synchronization of such rhythms. Among vertebrates several brain regions have been implicated as organizers of circadian rhythms: the lateral eyes, the re

This elaborate array of neuronal circuitry is capable of functioning under an enormous range of intensities. A number of separate mechanisms ensure that a level of neural activity is maintained that allows a functioning of the neurones connecting the retina to the brain at virtually all
