ZH-MGY type Y maze video analysis system 1 Introduction: Three-arm Y maze 120 degree angle to each other, were three equal radial. Application: has been used in a series of neurobehavioral basis of learning and memory, Effect of toxic chemicals and toxic effects of new drugs or new therapies. Material: Aluminum alloy stainless steel medical plastic electrical stimulation module. 2, the index definition: a safe area: bright lights arm, the arm is not energized at this time is a safe area (red light) non-security zone: no light arms and border zone are energized and become a non-secure area (electric shock zone) starting area : rat start where the start arm (shock zone) Incubation period: refers to the bright lights from the beginning until the 1st of rats fled lights consume time zone passive avoidance response times (error reaction times): fleeing rats started by electric shock After the district ran a non-secure area, and under the shock effect of the number of times they finally ran to a safe area of ??active avoidance response times :( correct response times): safe area lights, electrical stimulation not been made at the beginning of rats immediately fled to a safe area The number is the number of reflections of light and shade conditions to identify the active Flee: complete response times to escape the percentage of the total number of reactions in rats after 5s powered lights but not the number of tests: the test of time in the trajectory of the total number of tests in rats Figure: rat trajectory save the average speed in the maze to bmp image formats: movement from rat maze in unit time in three experimental process: 1) beginning of the experiment, the rats in the starting area (where the rats begin arm) adapt 3 ~ 5 min, and then changing positions clockwise safe area and electric shock zone, 2) indicator lights up when the safety zone after five seconds, that is, to the starting area, the non-secure area plus electricity, no safe zone power up, when the rats were electric shocks, run to a safe area after the end of a training session. 3) After the end of the last train into the original security zone under 5 seconds after the start of a training area, repeat the previous training process. Until the end of five minutes, within five minutes of training to get the number of the correct number of times, the incubation period, the number of errors, active Flee. 4) Note that the user can choose whether to five minutes can also be selected according to the number of select practice test mode (for example to be 5 times, 10 times, 20 times) 4, the indicator parameters: Indicator Specifications: The incubation period, the number of errors, the correct number the correct rate, error rate, the number of tests, track map, the resulting output excel format that can be used SPSS statistical MG-3S maze stimulator an overview MG-3S maze stimulator is my company after a number of universities have raised new and improved products, Customer old product really is not accurate timekeeping point, this maze accurate timing, LCD, the most important is that this maze increased latency automatic recording function, making it easier for the experiment. The equipment used in learning and memory, Alzheimer's, the hippocampus / hippocampus research, intelligence and aging, drug development / screening / assessment, pharmacology, toxicology, preventive medicine, neurobiology, animal psychology, behavioral biology and neurobiology scientific research and computer-aided teaching science and other disciplines experimental procedure: 1) beginning of the experiment, the rats in the starting area (where the rats began to arm) accommodate 3 ~ 5 min, then clockwise transform security zone and the location of electrical shock zone, 2) when the safety zone indicator lights up five seconds later, that is, to the starting area, a non-secure area plus electricity, safe area without electricity, when the rats were electric shocks, the end of a run to a safe area after training. 3) After the end of the last train into the original security zone under 5 seconds after the start of a training area, repeat the previous training process. Until the end of five minutes, within five minutes of training to get the number of the correct number of times, the incubation period, the number of errors, active Flee. 4) Note that the user can choose whether to five minutes can also be selected according to the number of select practice test mode (for example to be 5 times, 10 times, 20 times)
