Role of nitric oxide in responses of pial arterial vessels to low-intensity red laser irradiation

Bull Exp Biol Med. 2013 Sep;155(5):598-600. doi: 10.1007/s10517-013-2203-4.

Abstract

The responses of rat pial vessels to red laser irradiation can be mediated by NO. NO mainly affects major arteries and did not contribute to reactivity of small pial arteries and precortical arterioles.
