Background & Objective: The axial role of the oxidative stress in the pathophysiology of Parkinson disease has been identified. On the other hand, the learning and memory impairment in Parkinson disease has a distinguished outlook. Since Saffron has antioxidative stress effects, the aim of the present study is to investigate the improving effects of Saffron extract on the spatial memory paramet...

Introduction: Cognitive impairment is commonly associated with pain. The modulatory role of orexin 1 receptor (OX1R) in pain pathways as well as learning and memory processes is reported in several studies. The current study was designed to investigate the possible role of CA1-hippocampal OX1R on spatial learning and memory of rats following capsaicin-induced orofacial pain. Methods: Orofacial...

Background and Purpose: Learning disorder is one of the common disorders in students, which can lead to the occurrence of educational problems and secondary disorders in them. Based on psychopathological criteria, dyscalculia is one of the subcategories of learning disorder. Children with this disorder have problems in perception of spatial relations and in different cognitive abilities. Theref...

Introduction: Crystal meth by induction of free radical formation in brains cells and lipid peroxidation cause to the apoptosis. The aim of present study is to investigate the effect of extract of Scrophularia striataon spatial memory, lipid peroxidation and alteration of antioxidant enzymes levels. Methods: In this experimental study, 42 male Wistar rats were divided into 6 groups, including:...

Introduction: It has been reported that oral morphine dependency facilitated formation of spatial learning and memory. In the present study the role of NMDA receptors located in hippocampal CA1 area of morphine dependent rats was studied. Methods: Male rats were divided into 4 groups. Two cannulae were stereotaxically implanted bilaterally into the hippocampal CA1 area. After 5 days recover...
