Ugo Basile Passive Avoidance Apparatus
For the Mouse, Rat and Cat
The Basile Passive Avoidance Instrument is an efficient, reliable instrument for the classic passive avoidance task.
Rodents will normally crawl through a small opening into a darker chamber. If they are shocked in the dark chamber… this normal tendency is reduced, measured by longer latency or refusal to enter the dark chamber …that is, to passively stay where they are.
A unique elevator door design opens the passage to the dark side after a preset delay. The doors operate silently and automatically. Latency to pass through the doors is recorded with 0.1 sec. resolution. The controller allows digital setting of the shock intensity in milliamps.
