Ioglunide, a new nonionic contrast medium, has attracted attention by its virtual absence of immediate or delayed effect on brain electrical activity in animal studies. After 126 myelographies or cisternographies with ioglunide, routine electroencephalograms (EEG) and brain potential frequency analyses were performed in 109 and 73 patients, respectively.

Cerebellar circuitry is important to controlling and modifying motor activity. It conducts the coordination and correction of errors in muscle contractions during active movements. Therefore, cerebrovascular lesions of the cerebellum or its pathways can cause diverse movement disorders, such as action tremor, Holmes' tremor, palatal tremor, asterixis, and dystonia. The pathophysiology of abnorm...
