Estrogen can influence the expression of behaviors not associated directly with
reproduction, including learning and memory. However, the effects of estrogen on learning …

The effects of chronic estrogen treatment on radial arm maze performance and on levels of
central monoaminergic and amino acid neurotransmitters were examined in ovariectomized …

Gonadectomized male and female Sprague-Dawley rats, given estradiol (E 2) via sc Silastic
capsules that generated proestrus levels of hormones, were tested for spatial memory …

While estrogen enhances performance on some tasks of learning and memory, it has
impairing or no effects on others. It has been proposed that estrogen differentially affects …

Although several markers of synaptic efficacy are enhanced during proestrus, spatial water
maze performance is impaired. Because levels of both estrogen and progesterone are …

This study examined the effects of long-term estrogen treatment (sc 17β-estradiol
minipellets) on learning in C57BL/6J female and male mice using a position discrimination …

The effects of gonadal hormones and environment on performance in an eight-arm radial
maze and in the Morris water maze were determined in female rats. Long–Evans female rats …

Physiologically high levels of circulating estradiol enhance the use of place learning and
impair the use of response learning to find food on a land maze. These two types of learning …

Estrogen's role in learning and memory may be to predispose animals to use specific
cognitive strategies (Korol & Kolo, 2002). Specifically, estrogen may facilitate hippocampal …

Previous work has shown that continuous estradiol replacement in young ovariectomized
rats enhances acquisition of a delayed matching-to-position (DMP) T-maze task over that of …
