Sneezy twins.
A curious monozygous pair of twins producing sudden and vehement nose blowing and/or sneezing during/after eating and drinking, when their stomach had achieved a certain stage of fullness, has been observed. The sneezing reflex could be registered in 4 male members of the family. Since there were neither neurological disorders nor significant alterations in their electroencephalographic activity, the phenomenon may be regarded as a special type of hereditary vegetative sensitivity. The trait seems to follow either an autosomal dominant or perhaps a Y-linked mode of inheritance.
