• Allows editing protocols for both active and passive avoidance
• Experimental chambers can be controlled independently
• A test mode enables immediate and reliable box checking
• The program runs automatically when the animal is detected in the cage
• Animal position and current data can be visualized online
• Provides integrated data
• Analyze data in user-defined intervals of time

Passive avoidance is fear-motivated tests classically used to assess short-term or long-term memory on small laboratory animals (rat, mice).

Basically, passive avoidance working protocols involve timing of transitions, i.e. time that the animal takes to move from the white compartment to the black one after a conditioning session -in which the entry into the black compartment is punished with a mild inescapable electrical shock is carried out.

Our passive avoidance box (LE870/872) is defined by a large white illuminated compartment and a small black dark compartment separated by a guillotine gate. The animal's position is detected by using high sensitivity weight transducers providing higher effective and reliable detection of animal responses (zones entries) than systems based on photocells beams or on grid floor displacements.

Panlab/Harvard Apparatus Passive Avoidance boxes may be controlled either through LE2708 Programmer or ShutAvoid software. The first option is recommended for one single box set-ups, and may be combined with the included SeDaCom software. SeDaCom enables data transfer from the programmer to a PC through a RS-232 port. The connection is direct between programmer to a PC. No PCI card is needed! The link is carried out by one only cable from one Box to the other. The first Box is connected to PC or Laptop by the port RS-232 or USB. The second option is suitable for controlling a number of boxes simultaneously.
