 Background and Objective: Alzheimer’s disease is a prevalent central nervous system disease with no definitive treatment till now. So, in the present study the effect of an important herbal medicine, withania somnifera (Ws), was investigated on progression of Alzheimer’s disease.   Materials and Methods: We used intracerebroventricular streptozotocin (STZ) injection as a model for Alz...

Background and Objective: Intracerebroventricular (ICV) injection of streptozotocin (STZ) causes cognitive impairment in rats. The beneficial effect of saffron main component, safranal was investigated on ICV STZ-induced learning, memory, and cognitive impairment in male rats. Materials and Methods: For this purpose, rats were injected with ICV STZ bilaterally, on days 1 and 3 (3 mg/kg). The ST...

Intracerebroventricular (ICV) injection of streptozotocin (STZ) in rats is followed by long-term and progressive deficits in learning, memory, and cognitive performance which is somewhat similar to sporadic Alzheimer’s disease (SAD). Epidemiological studies suggest that non-steroidal anti-inflammatory drugs (NSAIDs) could delay or slow the clinical expression of SAD. Therefore, the benefi...

Background: Neurohormones like testosterone and estrogen play important roles in learning and memory. Estrogen receptors, densely expressed in the CA1 region of rat hippocampus, mediate the effects of estrogen on learning and memory. Estrogen receptors belong to a family of transcription factors, the nuclear receptor super family, and have two subtypes, estrogen receptor α and estrogen receptor...

Research on passive avoidance learning has demonstrated reliabledifferences between psychopaths and controls when avoidance errors result in electric shock but not in loss of money (Schmauk, 1970). Using monetary punishments, Newman, Widom, and Nathan (1985) found that psychopathic delinquents performed more poorly than controls in an experimental paradigm employing monetary reward as well as t...

Introduction: Gap junctions are specialized cell–cell contacts between eukaryotic cells through which they communicate. This type of communication has the potential to modulate memory process. We evaluated the effects of the gating of the hippocampal CA1 area gap junction channels on memory consolidation, using passive avoidance task. Materials and Methods: 72 adult male Wistar rats were distri...
