Abstract

Infrared neural stimulation (INS) has the potential to serve as a spatially precise tool for neuroscientists and clinicians. Because of difficulties comparing various INS techniques in the current literature, we present a study comparing the stimulation threshold and transition rate to 100% activation probability for diode and Ho:YAG lasers. The stimulation threshold was lower for the Ho:YAG than the diode lasers across all examined spot sizes. The Ho:YAG also exhibited a nearly binary transition to 100% activation that can be mimicked with diode lasers by decreasing the pulse width. These results will help maximize the performance of laser diodes for INS.
