First, T-shaped maze experimental experiment principle: is the color of the arm to food as animals Exploring the driving force. This model is usually studied by Spatial Working Memory, i.e., as used as information useful during the current operation. Improved T--shaped maze can also be used to evaluate the reference memory, that is, information recorded in this experiment, once a test.

Second, T-shaped maze experimental experimental method: 1 Training 2 u0026 nbsp D, touch mice and put it in T Maze to adapt 10 min, put food in the labyrinth arm bowl, and take it after being killed.

2 Training Experiment: Each Trial includes two parts, ie FORCED RUN and TEST Run. Forced Run: Select the one arm of the T labyrinth, close to the wood gate, and the mice can only enter the one arm to get food. After the food is finished, remove it immediately, wash with alcohol. 15 after s, the shutter withdrawn. TEST RUN: All of the arms open, put the mice into the start arm, if the mouse selects the arm that has not been entered, for the correct choice, give food reward; if you repeat the same arms, it is wrong to give food. . Each animal was carried out daily, 15 min each time, continuous 4 D, the correct rate of each group of mice per day was calculated. When the average correct rate reached more than 85%, the training phase ended. T Maze Experimental Method 3 Test Experiment: Extend forced u0026 Nbsp; Run and Test RUN time interval to 1min and 3min, calculate each group of mice, respectively The correct rate.

Third, observation indicators: Animal completion of the experiment Time, each exploration and the proportion of the previous arm.
