Abstract
A method and a device for label-free all-optical neural regulation and imaging are provided. The method stimulates a neural activity through an infrared laser pulse, and acquires an optical scattered signal caused by the neural activity by optical coherence tomography (OCT) to realize label-free all-optical neural regulation and imaging. The method specifically includes: aiming an infrared laser at a target brain region, injecting a certain time series of laser pulses, synchronously scanning and imaging the target brain region by OCT, analyzing a relative change of an OCT scattered signal before and after laser stimulation, and acquiring a brain function signal based on OCT to realize synchronous neural regulation and imaging. The method and the device enable synchronous neural regulation and imaging without causing crosstalk between the regulation and imaging channels, and without the need for injection of a contrast agent or viral transfection.
