Dynamic analysis of mental sweating of the sweat glands and peripheral vessels by optical coherence tomography

The sweat gland and peripheral vessels underneath skin are a typical minute organ governed by the sympathetic nerve, and have important physiology functions to control of body temperature and maintenance. In this paper, we demonstrated the dynamic analysis of the mental sweating of the eccrine sweat glands and the dynamics of the small artery of human finger by optical coherence tomography (OCT). In the experiment of mental sweating, not only time variation of the amount of excess sweat can be evaluated simultaneously a few tens of sweat glands eccrine sweat glands but also the dynamics of peripheral vessels of a human finger were analyzed.
