(a) Placement of the infrared light delivery fiber relative to the neuron. (b) Representative image shows the confluency of the neurons and the peak of the thermal gradient of a 2.73 ms ($0.52\mathrm{J}/{\mathrm{cm}}^2$) infrared light pulse. The thermal image was acquired with a FLIR thermal camera. Scale bar is $250\mu \mathrm{m}$. (c) SILP induced thermal gradient due to 0.52 and $0.96\mathrm{J}/{\mathrm{cm}}^2$ exposures.
