Optical Stimulation and Monitoring of the Peripheral Nervous System: Perspectives and Challenges Toward Clinical Translation

Laser &Photonics Reviews, EarlyView.
Optical neuromodulation with IR light allows stimulation of the PNS without the need for physical contact with the target nerve or without requiring any genetic modification. The clinical translation of this technique will pave the way to the development of neural interfaces for restoring sensory feedback in individuals with limb amputation.
