Background and purpose: Visual deprivation during critical period of brain development impairs structure and function of NMDA receptors in visual cortex. Parts of visual signals go to the hippocampus through the visual cortex. Therefore, this study aimed at investigating the effects of visual deprivation during critical period of brain development on NMDA receptor subunits expression in rats’ h...
abstract objective the last two decades have seen major advancements in our understanding of some of the most common neurodevelopmental disorders in the field of child neurology. however, in the majority of individual patients, it is still not possible to arrive at a molecular diagnosis, due in part to lack of knowledge of molecular causes of these tremendously complex conditions. common geneti...
AbstractObjectives: This research was conducted with the objective of examining the effect of three methods of creativity development (brain storming, forced association and synectics) on creativity development in second grade guidance school students in Shahrekord. Method: The present study was a pretest-posttest experimental design with control group. To measure the dependent variable, namely...
Neuroimaging research indicates that human intellectual ability is associated to brain structure including the thickness of the cerebral cortex. Most studies show that general intelligence is positively associated with cortical thickness in areas of association cortex allocated throughout both brain hemispheres. Changes in cortical thickness over time have been related to intelligence, but whet...
One of the most nervous system evolution are memory and learning in humans. Learning is a skill that enhances synaptic activity in the hippocampus of prefrontal cortex. In fact, basic passive learning is communication between the conditioned and Unconditioned stimulation. Passive learning involves three steps: habit, education and remember. According to the results of investigations, the hippoc...
The past 15 years have seen a rapid expansion in the number of studies using neuroimaging techniques to investigate maturational changes in the human brain. In this paper, I review MRI studies on structural changes in the developing brain, and fMRI studies on functional changes in the social brain during adolescence. Both MRI and fMRI studies point to adolescence as a period of continued neural...
Background: It is well known that the development of brain oxidative stress is one of the most serious complications of arterial hypertension that evokes brain tissue damage. The aim of this study was to examine the effects of atorvastatin treatment (20 mg/kg/day), as an antioxidant, to prevent the brain tissue oxidative stress in the hypertensive (HTN) rats. Methods: Experiments were performed...
ABSTRACTNeuroimaging allows noninvasive evaluation of the anatomy, physiology, and function of the brain. It is widely used for diagnosis, treatment planning, and treatment evaluation of neurological disorders as well as understanding functions of the brain in health and disease. Neuroimaging modalities include X-ray computed tomography (CT), magnetic resonance imaging (MRI), single photon emis...
the cannabinoidergic system acquired a reputation as the most abundant g-protein coupled receptor in the cns that acts as retrograde modulator of neurotransmitter release. recently, endocannabinoids (ecbs) have been highlighted as neurodevelopmental signaling cues that exert a regulatory role in brain development. the interruption in ecb system elements (including receptors and enzymes of synth...
