Summary The effects of tobacco smoking, sham smoking, intravenous administration of nicotine, a foot movement procedure, mental arithmetic and imaginary smoking on the vasoconstrictor response of hand resistance vessels to application of ice to the neck has been studied in normal subjects. All of the above procedures except imaginary smoking significantly reduced the ice response. The mechanism of this blocking effect is obscure, but a central inhibiting action, possibly at a cortical level, is postulated.
