Electroconvulsive therapy (ECT) is an efficient treatment for several neuropsychiatric disorders however a large number of patients develop memory impairment after ECT. Different studies both on animals and human suggest that vasopressin has positive effects on memory and improves cognitive functions. In this randomized, double-blind controlled clinical trial, 50 patients with psychiatric d...
Background: The hippocampus, a vital center for learning and memory, is extremely vulnerable to neurological diseases.Several reports of cognitive and memory impairment have been published in patients with Multiple sclerosis (MS). The prevalence of MS is highest where environmental supply of vitamin D is low. In the present study spatial working memory and reference memory after treatment with ...
Autobiographical memory, or memory for personal experiences, allows individuals to define themselves and construct a meaningful life story. Current research aims to review the definition and theories of autobiographies memory and how it usually changes or abnormally in older adults.

background several studies showed that dopamine and norepinephrine improve retention and retrieval of memory. methylphenidate is an enhancer of dopamine and norepinephrine in brain. objectives in the present study, the effect of methylphenidate was evaluated on retention and retrieval of memory in young and aged mice using passive avoidance apparatus. materials and methods animals were divided ...
the present study aimed to examine throwing accuracy and spatial and digit working memory of field dependent-independent participants. the group embedded figure test (geft) was distributed among 320 male students and based on the geft scores, 45 participants were randomly divided into field dependent, field independent and control group (15 participants/each group). the study included two tasks...
Abstract The aim of this study was to investigate the role of working memory capacity and errorless and errorful practice on the learning the relative timing was a motor task. 50 Participants based on were selected aged 22±4 years as accessible samples randomly assigned to one of four groups (errorless low working memory capacity, errorful low working memory capacity, errorless high working me...
Background and Objective: Memory naturally degrades with the passing of time.

After physical examination and blood sampling, they were in...
in the current study, we assessed the role of transient receptor potential (trp) channels on avoidance memory and anxiety states in ca3 area of the hippocampus. we explored the anxiety and avoidance memory states using test-retest protocol in the elevated plus maze to understand whether trp channels can affect the above mentioned states in ca3 area. to investigate the consolidation phase of mem...
