Computer automatic analysis process system of animal shuttle box
Technical field
The invention belongs to a kind of animal experiment device capable, particularly a kind of experimental facilities that shuttles back and forth that computerizeds control.
Background technology
Shuttle back and forth and be meant if animal does not react to a certain signal specific (as light, sound) at the appointed time, then give punitive and stimulate (electro photoluminescence commonly used), make animal shuttle to the offside place of safety (passive conditioned reflex), then can form initiatively fugue reaction (active condition reflection) within a certain period of time after the repetition training.Animal not only will learn to avoid punitive to stimulate in official hour, also will learn and remember certain signal (as light, sound) and the relation that punitive stimulates, and could form the active condition reflection.Therefore, the complicated learning and memory forming process of the most approaching reflection animal of shuttling back and forth is one of best behaviouristics method of testing of research meiofauna learning and memory behavior.
The at present domestic and international employed experimental facilities that shuttles back and forth, the shuttle box system that develops as Bioseb company is made up of shuttle box testing cassete, stimulator and computer system, and adopts pressure sensor detects the positional information in shuttle box of animal.Though this cover system has adopted calculator, stimulator is by manual operation start; Once can only observe a sample; Data message only can obtain the passive total degree that shuttles back and forth, total degree, the latent period of carrying out camera bellows, the intertrial interval number of times etc. that shuttles back and forth that shuttles back and forth initiatively.Equally also there is this problem in the shuttle box of selling as Columbus company in addition, and the shuttle box system of the said firm is positioned in shuttle box rat by photoelectric sensor.Though whole box body adopts the lucite system to become, outward appearance is exquisite, does not have much othernesses with Bioseb company on practical operation and the information content obtained.Existing shuttle box has a common defective, and that is limited by external condition exactly, and the repeatability of test is poor.
