Medial thalamic damage is a common cause of severe memory disruption in humans. Both the anterior thalamic nuclei (ATN) and the intralaminar thalamic nuclei (ILN) have been suggested as primary sites of diencephalic injury underlying learning and memory deficits, but their respective roles have yet to be resolved. The present study explicitly compared two spatial memory tasks in male PVGc hoode...
Exposure to chronic restraint stress in rats and psychosocial stress in humans has been shown to alter cognitive functions such as learning and memory and has been linked to the pathophysiology of mood and anxiety disorders. Antianxiety or sedative agents used in the management of stress have several disadvantages and undesired effects. Therefore, in this study, we investigated efficacy of a na...

BACKGROUND Chronic oxidative stress and inflammation severely affect the normal physiology of neurons and lead to neurodegenerative disorders such as Alzheimer's disease (AD). Polyphenols proved a boon in the prevention of dementia due to their antioxidant and neuroprotective potential. Caffeic acid phenethyl ester (CAPE) is a natural polyphenolic compound attributed with antioxidant, immunomod...
Effect of Capparis spinosa Linn. extract on lipopolysaccharide-induced cognitive impairment in rats.
Cognitive disorders in mankind are not uncommon. Apart from neurodegenerative diseases such as Alzheimer's (AD), various stresses also affect cognitive functions. Plants are known to be potential source of compounds that ameliorate several diseases including cognitive impairment. Here, we evaluated effect of aqueous extract of caper (Capparis spinosa) buds on lipopolysaccharide-induced cognitiv...
Eucommia ulmoides Oliv. Bark (EUE) is commonly used for the treatment of hypertension, rheumatoid arthritis, lumbago, and ischialgia as well as to promote longevity. In this study, we tested the effects of EUE aqueous extract in graded doses to protect and enhance cognition in scopolamine-induced learning and memory impairments in mice. EUE significantly improved the impairment of short-term or...
Cognitive impairment is a significant comorbidity of epilepsy. At present, the molecular/cellular mechanisms that underlie these cognitive impairments remain unknown. It seems likely that a complete understanding at the molecular/cellular level will require the use of rodent models. A number of rodent models of epilepsy are used to study cognition in a variety of behavioral tasks. This review p...
Purpose: To investigate the neuroprotective effect of natural flavonoid rhoifolin in rats with streptozotocin (STZ)-induced (AD).
 Methods: Morris water-maze and novel object recognition tests were carried out to estimate on memory cognition. Histopathological analysis was made observe thickness hippocampal CA1 pyramidal layer. Analysis oxidative stress markers performed hippocampus fronta...
Objective(s): Leptin is a hormone secreted by adipose tissue and is involved not only in the regulation of feeding and energy expenditure, but also its role in memory enhancement has been demonstrated as well. The partial transfer of leptin across the blood-brain barrier in obese individuals causes leptin resistance and prevents leptin reaching brain. On the other hand, studies have show...
Introduction: In the recent years, the use of several drugs such as cocaine and morphine has reduced, but the use of "club drugs" has increased in many countries. 3, 4-methylenedioxymethamphetamine (MDMA) which has known as ‘ecstasy’ among people has many harmful effects on serotonergic system in the brain. This system is responsible for learning and memory. In this study, we tested sub-acute a...
