Research to determine the role of gravity in neurosecretory physiologyIn an effort to determine the effects of gravity in regulating the synthesis, transport, storage, and release of octopeptides from the hypothalamo-neurophypophyseal system, the teleost fresh water fish was studied. A labyrinthectomized fish was subjected to a gravitational orientation of -G sub z for three days. Results show the fish had reduced levels of adenyl cyclose activity in its kidneys when compared to labyrinthectomized and unoperated fish exposed to normal gravitational orientation (+G sub 2) for the same period of time. Efforts were also made to determine the presence of vasopressin in the neurophypophysis and peripheral target organs.
