SENSORIMOTOR NEUROLOGY

Abstract

THE question is discussed whether the products of disintegration arising in the body, which act on the bloodvessels, may have an influence upon the permeability of the bloodvessels in the brain. Experiments performed on dogs showed that the pharmacological representative of such substances of disintegration, viz., histamine, enables fuchsin S to penetrate into the cerebrospinal fluid. Other experiments were performed in order to ascertain the regions in which this permeability is increased by histamine. M.
