ôbjective: ëmotional intelligence (ëï) is a set of competencies that enable us to engage in sophisticated information processing of emotions and emotion-relevant stimuli and to use this information as a guide for thinking and behavior. prefrontal cortexes (pfç) of brain and related regions have an important role in emotion and emotional regulation. âccordingly, we conducted a study to investiga...

Posttraumatic stress disorder (PTSD) is a disorder of emotional and mental stress occurring as an outcome of injury or severe emotional shock. Several Neuroimaging studies in humans have shown the functions and relationship between the anatomical changes of brain and PTSD. The three major areas of the brain are affected by PTSD .These three areas are the amygdala, hippocampus and prefrontal cor...

introduction: working memory plays a critical role in cognitive processes which are central to our daily life. neuroimaging studies have shown that one of the most important areas corresponding to the working memory is the dorsolateral prefrontal cortex (dlfpc). this study was aimed to assess whether bilateral modulation of the dlpfc using a noninvasive brain stimulation, namely transcranial di...

posttraumatic stress disorder (ptsd) is a disorder of emotional and mental stress occurring as an outcome of injury or severe emotional shock. several neuroimaging studies in humans have shown the functions and relationship between the anatomical changes of brain and ptsd. the three major areas of the brain are affected by ptsd .these three areas are the amygdala, hippocampus and prefrontal cor...

the human prefrontal cortex differs from all other mammals: the seat of complex cognition, abstract thinking, planning and future forecasting, and behavioral inhibition. using our prefrontal cortex is a significant energy drain on the body, so despite its impressive capabilities, it’s daily capacity is limited. some researchers estimate a mere 2-3 hours per day of activity depletes the prefront...

introduction: this study was conducted to determine the possible beneficial results of l-arginine on prefrontal cortex of rats which impressed by immobilization stress to define the synchronous impression of stress and nitric oxide (no) on evolution of prefrontal cortex of rats after birth. methods: forty-eight one month, male wistar rats were divided into two groups: stressed and non-stressed....

the purpose of the present study was to determine the role of medial prefrontal cortex (mpfc) dopaminergic system in fear conditioning response considering individual differences. animals were initially counterbalanced and classified based on open field test, and then were given a single infusion of the dopamine agonist, amphetamine (amph) and antagonist, clozapine (clz) into the medial prefron...

Introduction: This study was conducted to determine the possible beneficial results of L-arginine on prefrontal cortex of rats which impressed by immobilization stress to define the synchronous impression of stress and nitric oxide (NO) on evolution of prefrontal cortex of rats after birth. Methods: Forty-eight one month, male Wistar rats were divided into two groups: stressed and ...

aim of this research was exploring effect of transcranial direct current stimulation (tdcs) on working memory (wm) in dorsolateral prefrontal cortex (dlpfc) region in healthy people.the method used in this research was experimental with random assignment and control group. the population was male students of kharazmi university in range of 18 to 23 years old. thirty participant undertook three ...
