Abstract
In vivo, helium-neon and nitrogen laser beams guided by optic fiber to rat caudate nucleus decreased concentrations of dopamine and serotonin, while distant laser radiation to frontal cortex did not affect striatal dopamine. In vitro, laser radiation to pure monoamines and amino acids decreased concentrations only of aspartic acid and norepinephrine. The effects in vivo are attributed to a combination of photolysis and altered brain metabolism.
摘要
在体内，通过光纤引导氦氖激光束和氮激光束照射大鼠尾状核会降低多巴胺和血清素的浓度，而对额叶皮质进行远距离激光照射则不会影响纹状体多巴胺。在体外，对纯单胺和氨基酸进行激光照射仅降低了天冬氨酸和去甲肾上腺素的浓度。体内的这些效应归因于光解作用和大脑代谢的改变。
