Infrared neuromodulation (INM) is a safe optical method used to stimulate neuronal populations by locally changing the temperature within the brain tissue. Sleep and neural activity during sleep are highly temperature-dependent. During anesthetized in vivo measurements, the low-frequency components increase compared to vigilance. Therefore, we examined the changes in the frequency bands corresponding to delta and theta waves and sleep spindles during continuous infrared stimulation. The experimental device used for INM was a sharp-tip optrode, that holds an embedded waveguide that transmits in
