our neuropathological findings suggest that hypoxic myoclonus ( a ) does not seem to be explained by demonstrable neuronal loss in motor structures , such as cerebellum , thalamus , or basal ganglia and ( b ) does not appear to be causally related to a detectable reduction in the serotonin-containing neurons of the brain but rather to a functional derangement of anatomically intact serotonergic pathways originating perhaps from other , as yet unidentified , damaged neuronal structures .
