The nervous system evolved for hundreds of millions of years in the protected environment of earth, shielded from high-power laser light, microwaves, ultrasound, and other forms of human generated energy. Yet, perhaps enabled by naiveté, neurons respond to these unnatural stimuli. Nowhere is this more clearly exemplified than in the inner ear, where brief pulses of focused infrared laser light and brief packets of focused ultrasound have both been shown to evoke action potentials in afferent neurons. These atypical stimuli have also been shown to evoke muscle contraction in cardiomyocytes, intracellular calcium transients in glial cells, and synaptic release at the neuromuscular junction. Focusing the energy in brief pulses on single cells or small regions of tissue can locally excite or inhibit neurons through endogenous mechanisms. This lecture will describe these “unexpected” responses to infrared light and ultrasound in several model systems, both in situ and in vivo, with attention to the mechanisms of action as well as the promise and the pitfalls of application.
