A rich tradition of normative psychophysics has identified two ubiquitous properties of interval timing: the scalar property, a strong form of Weber's law, and ratio comparison mechanisms. Finding the neural substrate of these properties is a major challenge for neurobiology. Recently, advances have been made in our understanding of the brain structures important for timing, especially the basa...

 ABSTRACT Background: High resolution CT scan has made early diagnosis of intraventricular hemorrhage (IVH) easier. Posttraumatic intraventricular hemorrhage has been reported to a greater extent because of the CT scan. Methods: 904 patients were admitted in the NSICU from March 2001 to March 2002 with severe closed head injury, of those only 31 patients with intraventricular hemorrhage (GCS le...

Chorea is an abnormal movement characterized by a continuous flow of random muscle contractions. This phenomenon has several causes, such as infectious and degenerative processes. Chorea results from basal ganglia dysfunction. As the control of the eye movements is related to the basal ganglia, it is expected, therefore, that is altered in diseases related to chorea. Sydenham's chorea, Huntingt...

Neurological tumors, such as gliomas and meningiomas are rarely presented by movement disorders. Early detection of neurological both basal ganglia arising tumors ganglia-sparing ones, presenting with disorders is crucial to prevent any further deficits.

parkinsonism is used to describe a syndrome manifested by any combination of six cardinal features: tremor at rest, rigidity, bradykinesia, loss of postural reflexes, flexed posture and the freezing. decreased dopaminergic neurotransmission in the basal ganglia is the core biochemical pathology in parkinsonism. hereditary parkinsonism includes various heredodegenerative diseases such as hallerv...

Objectives: To mathematically model the oscillatory behaviour of Basal Ganglia for Parkinson’s disease as well to simulate by using Cell designer and Scilab. Method: The pathway Parkinsons was downloaded from KEGG database studied scilab programming cell tool. In this work, loaded designer, that is working on basis systems biology mark-up language, analysed entire pathway. Findings: oscillary b...
