Mingxiao experiment

Avoiding experiment is a good darkness of animals (clear dark shuttle) , It is established by the fear and memory of disgusting stimulation (such as a sufficient shock). Therefore, the evasion experiment is technically similar to the fear of implied association conditions for the experiment (rather than animals). The stimulation used is a mild foot electric shock, and the reaction occurs is where the animal escapes has been excited by electric shock. Divided into active avoidance and passive avoidance depending on the evasion of animals. The former requires animals to take the initiative to escape from hateful stimulating boxes; the latter requires animals to curb themselves without entering a hate stimulating box.

Second, a bright and dark tank experiment

1. Single electric shock stimulation training (1) Put the mice into the bright box, 10S, open the door between the bright and dark boxes. Most of the lines have a strong inquiry behavior, and they are dark. Therefore, mice will quickly enter the dark box.

(2) After the mice (limbs) entered the dark box, they immediately closed the mednet and administering an electric shock. The electric shock strength can cause small currents that can cause mice retreat and vocal. According to the mouse line, the current range is from 0.2 to 0.8 mA (100V, 50 ~ 60 Hz AC), lasting 1 to 2s.

. Clean the operating box. Carry out the next animal. 2. Retention Test Electrical Stimulation Training After 24 hours, put mice back into the box, open the door, but not to shock
