Embodiment Construction

[0024] Further description will be made below in conjunction with the accompanying drawings.

[0025] Such as figure 1 As shown, the optical stimulation system according to an embodiment of the present invention includes: a host computer and a main computer connected to the host computer. The upper computer receives the feedback information from the main machine, analyzes the feedback information and controls the main machine.

[0026] An analog-to-digital / digital-to-analog signal converter is arranged between the upper computer and the main body, and the analog-to-digital / digital-to-analog signal converter can also be arranged in the main body. The analog-to-digital / digital-to-analog signal converter receives the digital control signal sent by the upper computer and converts it into an analog signal to control the main machine, and converts the analog signal of the main machine into a digital signal and transmits it to the upper computer for processing and control.

Abstract

The invention relates to a light stimulus system and a control method thereof, which comprises a host computer and a main machine that comprises an emitting illuminant, optical fiber, a dichroic mirror and an stimulated luminescence detector, wherein the emitting light emitted by the emitting illuminant is transferred by the optical fibre to stimulate light perception gene cells and generate stimulated luminescence which is reflected to the stimulated luminescence detector by the dichroic mirror and transferred to the host computer for processing and control; one end of the optical fibre is connected with the emitting illuminant, the other end of the optical fibre is a free end, and the host computer adjusts the moving travel of the free end of the optical fibre as well as the emitting illuminant according to whether to receive the stimulated luminescence; the light stimulus system stimulates the light perception gene cells to generate the stimulated luminescence and feed backs to the host computer by the emitting illuminant, and the host computer automatically controls the moving of the optical fibre according to the information of the stimulated luminescence, simultaneously controls and adjusts the emitting illuminant to realize automatic control of the entire stimulating recording process, utilizes the optical fibre to stimulate and sample, and has small wound.

Description

【Technical field】 [0001] The present invention relates to a medical device, in particular to a light stimulation system and a control method thereof. 【Background technique】 [0002] Traditionally, when the light-sensing gene regulation technology is used for experimental operation, the optical fiber is implanted through the stereotaxic device according to the reading by means of a stereotaxic atlas (such as a stereotaxic atlas of the brain). The "blind insertion" method is adopted in the operation process of this positioning method, which cannot objectively detect and control whether the optical fiber can accurately reach the target area. A metal electrode is connected to the optical fiber head, and the electrode is implanted into the site to be tested (such as the cortex in the brain skull), and it is judged whether the electrode is in the target area according to the electrical activity form of the cells after the experiment. Adding electrodes to the optical fiber head fo...
