in this study, we focused on the gait of parkinson’s disease (pd) and presented a gray box model for it. we tried to present a model for basal ganglia structure in order to generate stride time interval signal in model output for healthy and pd states. because of feedback role of dopamine neurotransmitter in basal ganglia, this part is modelled by “elman network”, which is a neural network stru...

conclusion statistical analysis of susceptibilities of ms patients versus healthy subjects found no excess deposition of calcium content in deep gray matter of ms patients. calcification may not be considered as a biomarker of prognosis in ms. results magnetic susceptibility(x) of calcium content was assessed by number of pixels induced by gp and put in ms patients as well as healthy subjects. ...

introduction:dystonia is a disorder of movement caused by various etiologies. laryngeal dystonia is caused by the spasm of laryngeal muscles. it is a disorder caused by vocal fold movement in which excessive adduction or abduction of the vocal folds occurs during speech. the pathophysiology of this type of dystonia is not fully known. some researchers have suggested that basal ganglia structure...

fahr’s disease is a progressive and idiopathic basal ganglia calcification with normal metabolism of calcium and phosphor with motor and psychiatric signs and symptoms. dementia, chorea attetosise, psychosis and depression due to fahr’s disease are frequently reported, but fahr,s disease with bipolar mood disorder manifestation is very rare and we found only 3 case in review of literature from ...

Twenty-four adult molly fish (Poecilia sphenops, Valenciennes 1846) were collected to study the morphology and distribution of ganglia using histological, immunohistochemical, electron microscopy focusing on their relation immune cells. The classified spatially into cranial spinal, functionally sensory autonomic. Spinal (dorsal root ganglia, DRG) contained large close ganglionic cells, enclosed...

Background: Multiple treatments exist for pediatric patients presenting evaluation of wrist ganglia, most commonly surgical excision or percutaneous treatment. Treatment modality is often dictated by patient preference and recurrence rate. Compared with adult literature, treatment outcomes ganglia in children are less examined. This study examines rates after ultrasound-guided (USGT) a populati...

Introduction: Addiction imposes a large medical, social and economic burden on societies. Currently, there is no effective treatment for addiction. Our struggle to decipher the different mechanisms involved in addiction requires a proper understanding of the brain regions which promote this devastating behavior. Previous studies have shown a pivotal role for insula in cigarette smoking. In this...
