The Rodent Step-Down Avoidance Task is widely used in observing the effects of drugs on memory and learning, which is especially suitable for the initial screening of drugs, such as brain enhancement, memory improvement, anti-aging and other nervous system care. The Step-Down device adopts microcomputer control and to be well distinguished the rodent step down. Researcher set the test time and the controller record the incorrect times and the step-down latency, the retention latency is to be measured as aversive learning and memory. The longer the retention latency, the better the memory.
