Modulation effects on in vivo neural activity induced by near-infrared ray stimulation to the mouse inferior colliculus

Abstract (in Japanese) (See Japanese page) 
(in English) In recent years, more attention has been received to infrared neural stimulation (INS) which can modulate the activity of neural tissue through near-infrared light irradiation mainly owing to temperature changes. The inferior colliculus (IC) is one of the potential targets to treat auditory diseases and apply artificial hearing devices because it is one of the crucial relay nuclei where all auditory pathways converge during sound processing. However, there have been no previous reports of INS-induced modulation of neural activity in the IC. In this study, a mathematical model of brain tissue was first simulated, temperature distributions were numerically calculated, and stimulus parameters were selected from the simulation result. Subsequently, INS was administered to the IC of anesthetized mice, and the modulation effect on neural activity was measured using an electrophysiological method. On the basis of the results, we discuss how INS was effectively applied to neuromodulation.
