The neurobiology of functional neurological disorders characterised by impaired awareness. The authors suggested that these findings may point to a role for the basal ganglia and diencephalon (structures particularly vulnerable to such insults) in the emergence of conversion symptoms. The authors comment that the basal ganglia and thalamus are strategically placed in neuronal circuits to modulate sensory and motor signals and thus may affect conscious sensory processing or willed action. "Conversion" or "conversion reaction" refers to the process whereby intrapsychic distress is converted into physical .
