Passive Avoidance - Step through Passive Avoidance - Step through

The Passive Avoidance Set-Up (step-trough method) by Ugo Basile, is an efficient and reliable insturument fo the classic Passive Avoidance Test. 

Multiple configurations can be controlled by the NEW  electronic with touch-screen, which encompsses a precision 8-pole shocker.

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!


Passive Avoidance Test is used to assess memory function based on the association formed between a specific environmental context, which the animal learns to avoid, and an aversive stimulus, represented by a mild foot shock. The tests are conducted in a two-compartment apparatus, where one is dimly lit and preferable to a rodent, and the other is brightly lit.

Ugo Basile Passive Avoidance set-up instrument basically consists of a Controller, and a Cage divided into two compartments by a partition which embodies a sliding door. The tilting floor ensures a simple and relaible detection mechanism to score the animal’s movement across the two compartments.The 40500-001 Programming/Recording Unit, encompasses all controls, incorporates a constant-current high precision 8-pole shocker, and manages data acquisition: data are stored insite the unit and can be downloaded via the USB key provided as standard, for further processing via Excel, Access, etc.

The Unit, which incorporates a 12” touch-screen, manages both Passive and Active Avoidance Tests. Up to 4 cages can be connected to the same Controller. If more than one cage is connected, an expansion box 40500-005 is required for each additional cage. 

Remote Control feature will make remote service and software upgrades extremely simple!

    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 Alzheimer-type demen-tia, including the search for new drugs of potential therapeutic value, consisting of atten-uation 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).
