Theses and Dissertations
Previous research has yielded inconsistent results regarding the effects of caffeine on memory. Such inconsistency is likely to a large extent a function of the complex interaction effects of caffeine and other variables such as estrogen. The purpose of the present study was to discern possible variation in the effects of caffeine on the recall of prose for females tested during days 1-5 or 9-13 of their menstrual cycle. One hundred and seven subjects received either O mg/kg, 2 mg/kg, or 4 mg/kg of caffeine. Following an absorption period, subjects read six passages from a computer terminal and immediately afterwards, …

The Hormones Of Pregnancy Alter Somal Size In The Medial Preoptic Area Of The Rat Brain, Lori A. Keyser
Master's Theses
Formerly non-responsive females will display maternal behavior (MB) following pregnancy and parturition. The behavioral alterations are believed to occur in response to hormonal changes that accompany pregnancy. The medical pre optic area (MPOA) regulates hormone-induced MB. The current study examined neuronal changes which might account for the modified behavior. Twenty adult female Sprague-Dawley rats were assigned a hormone condition: ovariectomized (OVX), ovariectomized/hormone-treated (P+E2), intact diestrus (DI), or pregnant (PREG). Animals were killed, and their brains fixed in Golgi-Cox solution. Somata of the MPOA and related cortex were measured in each group using a Bioquant imaging system. Pregnant females …
