A STUDY OF THE INFLUENCE OF THE CHARACTER OF AN EXAMINING ROOM ON THE PERIPHERAL BLOOD VESSELS OF NORMAL, HYPERTENSIVE, AND SENILE SUBJECTS 1

Abstract

When a "laboratory" was converted into a conventional bedroom the frequency of reaction on the part of peripheral blood vessels increased when sensory stimuli were applied at distant parts of the body. This was apparent not only in groups of hypertensive and senile subjects but also in single subjects studied under both circumstances.
