Main outcome of study (acc. to author)
A small but statistically significant increase in the reflex response was revealed in the first series of experiment, which indicates enhancement of the synaptic transmission . However, this effect was not observed in a second series of experiments in which the incident power density was increased from 10 mW/cm² to 20 mW/cm².
