Abstract

The invention discloses a wireless program-controlled optical stimulation device, comprising: a host computer; a wireless transmission module; a stimulator, which is wirelessly connected with the wireless transmission module, and the stimulator is fixed on a target animal; an optical pole, which includes The substrate, the LED soldering pad arranged at one end of the substrate, and the tail interface provided at the other end of the substrate, several LEDs are welded on the LED soldering pad, and the end of the light electrode soldered with the LED is implanted into the In the target animal, several LEDs reach the target light-sensitive brain area, and the tail interface on the other end of the light pole is exposed outside the body of the target animal, and the tail interface is connected to the stimulator through the PFC connector. wire connection. The device of the present invention is used on small animals for studying optogenetics neuromodulation technology, cancels the optical fiber module to solve the technical problems of optical power decline and low stimulation efficiency during the stimulation process, and the whole device realizes micro-load wireless control, multi-point Nerve stimulation.

Description

technical field [0001] The invention relates to a light stimulation system, in particular to a wireless program-controlled light stimulation device. Background technique [0002] Optogenetic neuromodulation technology has the advantages of high specificity and high temporal and spatial resolution. The traditional optical stimulators used in this technology are mostly based on fixed-wavelength lasers, and then transmit the light to the neurostimulation of the light-sensitive gene brain area through optical fibers. target. The laser itself is expensive and bulky, which makes the system integration not high, and the wired conduction of optical fibers limits the in vivo neural regulation of living animals. One solution to the in vivo neuromodulation of animals is to provide light-duty wireless light stimulation systems. [0003] The current wireless optical stimulation system generally includes a host computer, a wireless communication module, a stimulation control module, a l...
