Pre-operative determination of the dominant hemisphere for speech and speech associated sensory and motor regions has been of great interest for the neurological surgeons. This dilemma has been of at most importance, but difficult to achieve, requiring either invasive (Wada test) or non-invasive methods (Brain Mapping). In the present study we have employed functional Magnetic Resonance Imaging...

Traumatic brain injury is a serious global health problem with irreversible high morbidity and disability and Because of its unknown pathophysiological mechanisms, efficient therapeutic approaches to improve the poor outcome and long-term impairment of behavioral function are still remains lacking. The microglial cells are the resident macrophage cells of the brain and have M1/M2 phenotype, for...

parkinson's disease (pd) is a very common neurodegenerative disease among the elderly population. current treatments for parkinson’s disease are based on symptom therapy but not the underlying cause of the disease. this disorder is caused neuronal death which triggers the activation of resident glial cells. this situation leads to neuroinflammation in the central nervous system. activated ...

p2x7 receptors are purineric receptors that are extracellular atp-gated ion channel. these receptors require high dose or prolonged exposure to atp for initial activation. the activation of these receptors facilitates the formation of inflammasome which activates caspase 1. the p20 and p10 subunits of caspase 1 form active enzyme that then releases active interleukin (il)-1 β and il-18, tumor n...
