[Repeated exposure in hypergravity: morphology of locus coeruleus, hypothalamic paraventricular nucleus and vagal nerve dorsal nucleus in rats].

摘要: As compared to analogous single rotation at 2 g and in contrast 5-d repeated exposures Coriolis accelerations, 5-day hypergravity (2 generated by centrifuge rotation) gave rise structural alterations rat's neurons of locus coeruleus, vasopressinergic the lateral magnocellular subnucleus paraventricular nucleus nervi vagi dorsal suggesting involvement these structures brain mechanism facilitation adaptation long-term hypergravity. Results study point ability mammals remember changes gravity. Findings may help develop an algorithm intermittent exposure artificial gravity aboard space vehicle.
