Condition Avoidance Test Apparatus

The Conditioned Avoidance Test Apparatus is a behavioral experimental setup used to study learning, memory, and anxiety in animals, typically rodents. The apparatus generally consists of a chamber divided into two or more compartments. One compartment is designated as the "safe" zone, while the other is associated with an aversive stimulus, such as a mild electric shock.

During the test, the animal learns to associate certain cues (such as a light or sound) with the impending aversive stimulus. The animal's ability to avoid the aversive compartment in response to these cues is measured to assess its learning and memory capabilities. This apparatus is commonly used in research on neuropharmacology, cognitive function, and the effects of various drugs or treatments on anxiety-related behaviors.
