Abstract Objective. To design and implement a setup for ex-vivo optical stimulation exploring the effect of several key parameters (optical power pulse duration), activation features (threshold, spatial selectivity) recovery characteristics (repeated stimuli) in peripheral nerves. Approach. A nerve chamber allowing electrical was designed built. 1470 nm light source chosen to stimulate nerve. p...
