background: chronic daily headache (cdh) has gained little attention in functional neuro-imaging. when no structural abnormality is found in cdh, defining functional correlates between activated brain regions during headache bouts may provide unique insights towards understanding the pathophysiology of this type of headache. methods: we recruited four cdh cases for comprehensive assessments, in...
• Resting microglia continuously survey the brain environment maintaining homeostasis in physiological conditions. Brain injury, therapeutic irradiation and galactic cosmic ray exposure trigger activation cognitive dysfunctions. Microglia depletion complete repopulation prevent impairments after different injuries to brain. are resident immune cells of central nervous system (CNS). In condition...
Abstract Several clinical studies have reported a double dissociation between abstract and concrete concepts, suggesting that they are processed by at least partly different networks in the brain. However, neuroimaging data seem not line with neuropsychological reports. Using ALE method, we run meta-analysis on 32 brain-activation imaging considered only nouns verbs. Five clusters were associat...
Introduction: Various treatment methods for drug abusers will result in different success rates. This is partly due to different neural assumptions and partly due to various rate of relapse in abusers because of different circumstances. Investigating the brain activation networks of treated subjects can reveal the hidden mechanisms of the therapeutic methods. Methods: We studied three groups o...
