Low energy laser treatment of patients with nerve injuries has been reported to achieve enhanced return of sensation in treated patients. Animal studies have shown reduction in scar formation and improved function following laser treatment of crushed sciatic nerves. However, these results remain controversial. Other clinical and animal studies fail to find any laser effect, and the biological basis for an effect has not been established. Studies of cultured fibroblasts have produced conflicting results, and there is little in vitro data regarding laser effects on nerve tissue. The purpose of this study was to determine the effects of GaA1As low energy laser irradiation of rat cerebral cortical cells, and human nerve cells in vitro.
