Background: Many studies have shown that zinc has an important effect on learning, memory and cognition. On the other hand, ovariectomy in adult female rats reduces memory and learning. Also, regarding the contradictory reports on the effects of zinc chloride on memory and learning, this study aimed to examine the effect of zinc chloride on passive avoidance memory of ovariectomized female rats...
abstract background and objective: alzheimer’s disease (ad) is a weakening neurodegenerative disorder typified by increased b-amyloid (ab) deposition and neuronal dysfunction causing to impaired learning and memory. among proposed risk factors, induced oxidative stress is a main cause for incidence of the disease. the aim of this study was to determine the effects of the rosmarinic acid on lear...
BACKGROUND AND PURPOSE The purpose of this study was to investigate the behavioral changes, in particular retention of memory, after focal cerebral ischemia in rats.
