Central Pain Syndrome
Central pain syndrome is pain initiated or caused by injury or dysfunction in the central nervous system. Recent research suggests that the development and maintenance of such pain could link to abnormal inhibitory regulation by the zona incerta of the posterior thalamus. It has been suggested that there exists
a significant suppression of both spontaneous and evoked activity in inhibitory neurons in zona incerta and abnormally high spontaneous and evoked activity of neurons in posterior thalamus in animals with central pain syndrome. The positive association between behavioral and neurophysiological thresholds in rats with central pain syndrome is consistent with a causal role for suppressed incerto-thalamic inputs in central pain syndrome.
