Wireless program-control light stimulation device

Abstract

The invention discloses a wireless program-control light stimulation device which comprises an upper computer, a wireless sending module, a stimulator and a light pole, wherein the stimulator is in wireless connection with the wireless sending module, and the stimulator is fixedly arranged on the body of a target animal; and the light pole comprises a substrate, an LED bonding pad arranged at one end of the substrate and a tail interface arranged at the other end of the substrate. A plurality of LEDs are welded on the LED bonding pad; the end, welded by the LEDs, of the light pole is planted into the body of the target animal to enable the plurality of LEDs to reach a target light-sensing brain area; the tail interface at the other end of the light pole is exposed out of the body of the target animal; and the tail interface is in wire connection with the stimulator through a PFC connector. The device is applied to the bodies of the small animals for studying the optogenetics nerve regulation technology, and avoids fiber modules, so that the technical problems of optical power recession and low stimulation efficiency in the stimulation process are solved; and the whole device realizes micro load wireless control and 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...
