For solving the problems of the technologies described above, the animal event related potential recording system that this utility model designed comprises body, and said body comprises opaque outer box and transparent inner box, and inner box is nested in the outer box, and laboratory animal places inner box; Be equipped with air-vent on the above-mentioned inside and outside box; Be provided with sound-producing device and illuminator in the outer box; The head heeling-in of laboratory animal has recording electrode and reference electrode, this recording electrode and reference electrode to draw lead box outside inner box inside leads to outside, and be connected with oscillograph via preamplifier.Native system passes through sound-producing device as the auditory stimulus source; Illuminator is as the visual stimulus source; The air-vent that passes on the inside and outside box with wooden stick touches laboratory animal as somesthesia stimulus such as sense of touch, the pains sensation; Realization vision, audition, somesthesia are brought out current potential and are detected, and note laboratory animal brain wave diagram data.
Said sound-producing device can be the speaker more than 1 or 1; But realize stereophonic effect in order to make the generating means in the outer box; Raising is to the auditory stimulus of laboratory animal; Said generating means is preferably 4 speakers, and 4 speakers are installed on respectively on the equidistant outer box sidewall in distance outer box center.
In order to bring out the visual stimulus of laboratory animal to different lights, said illuminator is preferably the illuminating lamp of adjustable brightness joint.
In order to prevent that drawing lead causes interference to laboratory animal, said recording electrode of such scheme and reference electrode draw lead from inner box with outside the bottom that links to each other of box directly draw.
The said inner box of such scheme is provided with moveable bulkhead, and this moveable bulkhead is connected to relative sidewall from inner box one sidewall, inner box is separated into the compartment of two independent sealings.Usually when animal being carried out the event related potential experiment, limit the activity of animal, the size through moveable bulkhead is regulated inner box can be used for the experiment of different build animals.
For the air that increases outer box and inner box flows and improves the thermo aesthesia in the somesthesia of laboratory animal is stimulated, the air-vent that said outer box is provided with is 2, and one of them air-vent is positioned at outer box bottom, and another air-vent then is positioned at outer box top.
The said oscillographic outfan of such scheme is connected with printer.
Compared with prior art, the utlity model has following advantage:
1, laboratory animal is carried out the detection of the multiple CEP of vision, audition, somesthesia, and the brain wave experimental data when laboratory animal receives incident and brings out under the real time record;
2, laboratory animal being carried out stereophonic audition stimulates, and makes that intensity of sound difference is little, improves the accuracy that auditory evoked potential detects;
3, laboratory animal is being carried out in the visual stimulus,, realizing the detection of visual evoked potential down of different lights through regulating the brightness size of light source;
4, be provided with moveable bulkhead in the inner box, can be fit to the experiment of different build animals, increased the scope of application.
5, native system is simple in structure, is easy to realize, and receives external influence little, and degree of accuracy is high.
