40570 - Passive Avoidance - step down NEW MODEL

Passive Avoidance - step down Passive Avoidance - step down

The Passive Avoidance step-down cage, for mice or immature rats, is based on the stepdown scheme in which the animal is dropped on an elevated platform which becomes uncomfortable because of vibrations.

The instrument basically consists of an arena, shaped as a cage (Cat. No. 47573) and a control unit with touch-screen 40500-001, with the related application software 40570-010.

The P.A. set-up is part of UB conditioning-cage project; you buy a single touch-screen controller, and manage all UB cages. Ask for details!

A 7 cm platform elevated above the floor grid of a 28x23cm 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 is selectede from 10 to 10Hz, in 10 steps (10Hz each). The shock intensity can be preset in the range 0 to 3mA, in steps of 0.1mA. A delay up to 15 seconds can be set in steps of 1s.

    Behavioral scientists are well acquainted with passive avoidance methods that have been used for several decades, originally by psychologists, who were interested in animal behavior.

    These procedures were later exploited by neuroscientists, who specifically perform sys-tematic studies of the behavioral changes mainly produced by brain lesions, to define the functions of different C.N.S. sections.

    The Passive Avoidance was soon extended to several other areas of research such as behavior genetics, psychopharmacology and behavioral toxicology.

    More recently, such use has become routine in animal model studies of aging and of Alz-heimer-type dementia, including the search for new drugs of potential therapeutic value, consisting of attenuation of behavioral deficits.

    The Passive Avoidance task is a one trial fear-motivated avoidance task, classically used to assess short-term or long-term memory on small laboratory animals (rodents).

    Passive Avoidance is a broad term that includes an ample selection of methods and an equally wide variety of different versions of each method.

    In our Passive Avoidance instrument one exploits the tendency to step down from a vi-brating, hence definitely uncomfortable floor section.
