While the vessels of the cerebral cortex react to mechanical, thermal, chemical and electric stimuli,2 and while pial arteries have been seen to go into spasm on being stretched3 or on increase of blood pressure,4 little evidence has been forthcoming from these sources that any nervous control is clinically significant.
