7570 - Passive Avoidance - step down
The Step Down Passive Avoidance system has been designed for use with Adult Mice or juvenile rats and is based on the step-down scheme in which the animal is dropped on an elevated platform which becomes uncomfortable because of vibrations and the mouse steps down to an electrified grid.
The Passive Avoidance step-down version, for mice or immature rats, Cat. 7570

A 7 cm platform elevated above the floor grid of a 6 x 10 x 10" box provides the arena for Step Down experiments.
The platform is connected to an actuator which causes the platform to shake. When the animal steps off of the platform to the electrified grid, the stop command is used to cut actuator power, halt platform vibration, and trigger the latency counter.
Latency time is recorded to 1/10 of a second. The vibration intensity can be changed by a thumb switch on the front panel of the instrument. An 11 cm platform is also included with this set-up, for using with larger animals.
