title: [Effect of consumption of sucrose and saccharin on passive avoidance learning in female Wistar rats].
abstract: Influence of consumption of 32% sucrose or 0.1% saccharin solutions on passive avoidance acquisition in female Wistar rats was studied at different stages of estrous cycle. Under conditions of weak electrical shock, rats of the control and saccharin groups showed no acquisition at any stage of estrous cycle. Under the same conditions females of the sucrose group acquired the avoidance behavior if trained on the first day of diestrous and metestrous but not proestrous and estrous. The stage of estrous cycle on the second day did not influence the latency during testing session.
