Electrophysiological studies on ciguatera poisoning in man (Part II)

J Neurol Sci. 1991 Jan;101(1):93-7. doi: 10.1016/0022-510x(91)90022-y.


Fifteen cases of acute ciguatera poisoning were subjected to electrical studies on the sural and common peroneal nerves. Significant slowing of sensory conduction velocity and prolongation of the absolute refractory, relative refractory and supernormal periods were recorded. These findings indirectly suggest that ciguatoxin causes an abnormally prolonged sodium channel opening in nerve membranes.
