Embodiment Construction
[0023] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only the parts related to the present invention are shown in the drawings but not all of them.
[0024] Such as figure 1 with figure 2 As shown, the present invention provides a biological tissue photostimulation device, comprising a bottom bracket 10 and an upper cover 20, the materials of the bottom bracket 10 and the upper cover 20 are all opaque materials or selectively opaque materials, the bottom bracket 10 and the upper cover 20 The upper cover 20 is fastened to form an accommodation chamber, in which a nutrition supply source 30 is arranged, and the accommodation chamber has a top opening an...

The invention relates to the technical field of biological experiments, in particular to a biological tissue light stimulation device, the receiving cavity having a top opening and a bottom opening, one of the two openings for admitting a target tissue into the receiving cavity and the other for admitting a light source into the receiving cavity. The material of the bottom support and the upper cover is opaque material or selective opaque material. As that light source and the target tissue are both locate in the accommodation cavity, and the bottom support and the upper cover are opaque whenthe light shield device is used for the light stimulation experiment, the influence on the non-target tissue outside the accommodation cavity is effectively avoided when the light source is used for the light stimulation on the target tissue; as that nutrient supply source in the contain cavity is arranged, a suitable nutrient or isotonic environment can be provide for the target tissue, and dehydration of the target tissue can be avoided.
Description
technical field [0001] The invention relates to the technical field of biological experiments, in particular to a biological tissue light stimulation device. Background technique [0002] Optogenetics technology is a method of controlling cell activity by using a combination of optical technology and genetic technology. The key to this technology is: first transfer a special light-sensitive protein gene to a specific cell of the animal, and the gene expression product can respond sensitively to the stimulation of different colors of light, and then use different colors of laser light to Activate or inhibit cell function. [0003] There are usually two methods for existing in vivo photostimulation methods: the first method is to implant a section of optical fiber and an access port at a specific position of the experimental animal. The light is passed into the designated area and irradiated near the target tissue; another way is to directly extend the light source into the ...
