introduction: a fixed hemodynamic response function (hrf) is commonly used for functional magnetic resonance imaging (fmri) analysis. however, hrf may vary from region to region and subject to subject. we investigated the effect of locally estimated hrf (in functionally homogenous parcels) on activation detection sensitivity in a heroin cue reactivity study. methods: we proposed a novel explora...

Background and Aim: In epileptic patients, behavioral disorders are the most important deficits therefore evaluation of deficits by animal model should be essential. The role of Zinc in behavioral disorder and its relation with hippocampus or serum zinc may help explain why some brain region is commonly facilitated while other did not harm. The main purpose of this study was to evaluate Zinc it...

Introduction: Encoding models are used to predict human brain activity in response to sensory stimuli. The purpose of these models is to explain how sensory information represent in the brain. Convolutional neural networks trained by images are capable of encoding magnetic resonance imaging data of humans viewing natural images. Considering the hemodynamic response function, these networks are ...

Background & Aim: People with diabetes are potentially threatened by other factors such as negative emotions, nervous system defects, and sensitivity to anxiety, which affects whether or not they are affected by diabetes-related wounds. The aim of the study was to investigate the effect of brain-behavioral system on diabetic female patients exposed to psychological vulnerability with the mediat...

If the development of machine learning and artificial intelligence plays a role in many fields research technology today, it has special relationship with neurosciences. Indeed, historically inspired by our knowledge brain, deep shares some vocabularies neurosciences can sometimes be considered brain’s model. Taking particular example seizure, which develop any biological neural tissue, we ques...
