Embodiment Construction

[0035] figure 1 Schematic diagram of the stereotaxic device for gecko brain. As shown in the figure, the U-shaped support 6 is fixed on the base 5 through three pillars. The left and right eye bar holders 2 and 3 are connected with the U-shaped support 6 by eye bar fastening screws 1 and 4 respectively. The mutual positions of the left and right eye rod holders 2 and 3 can be adjusted by turning the two eye rod fastening screws 1,4. The gecko adapter 8 is connected with the U-shaped support 6 by the adapter fastening screw 7 . Rotating the adapter fastening screw 7 can adjust the overhang position of the gecko adapter 8 on the U-shaped support 6 .

[0036] figure 2 It is the assembly structure diagram of the left and right eye rod holders. As shown in the figure, a through hole and a blind hole are drilled on the upper chuck 10 of the eye bar, and the locking screws 9 and 13 are connected with the two threaded holes on the eye bar 11 through these two holes, and the lock...

Abstract

The stereo gecko brain locating method and device belongs to the field of locating technology. The present invention utilizes the unique condyles in the mandible joint and the maxilla joint as well as the maxilla site to determine one locating reference plane for locating the head of gecko completely. The corresponding device consists of locating needles, 3D electrode shifting unit, U-shaped seat, right and left eye rod holder, gecko adaptor, etc. The present invention has the features of accurate location and simple operation, and is suitable for the lab research of brain of reptile.

Description

technical field [0001] The gecko brain stereotaxic method and device of the present invention belong to the technical field of positioning and are used for the stereotaxic experiment of gecko brain. Background technique [0002] The 21st century is the century of the brain. To understand the functions of different regions of the brain and obtain their EEG signals, it is necessary to accurately place microelectrodes in predetermined locations. Precise and accurate stereotaxic methods and settings are necessary tools to achieve the above goals. When the subject's head and the localizer are fixed to each other, the target points in the brain can be marked on the stereotaxic device. That is, a three-dimensional coordinate can be used to determine the location of the neural structure. The stereotaxic system indicates the distance between the neural structure and the intersection of three zero planes or a certain point on the skull (such as fontanel, the tip of the herringbone s...
