A Y-Maze for Cats
Source: Psych Reports 1977;40:1071-1074.
Author: Toga AW
Abstract:
A Y maze was adapted for conditioning studies in cats. The apparatus can deliver aversive and appetitive reinforcement and variety of stimulus events. this device appears sensitive enough to detect perceptual, postural, and motor deficits induced by small brain lesions. Shuttle-box avoidance is often used to study specific functional changes resulting from the alteration of brain function following ablation or the administration of a drug. One of the major limitations of this procedure might be calle the go,no-go dilemma. This refers to the confounding of discriminative capacity with the general ability to perform or inhibit active responses. This is an inherent feature of the shuttle-box procedure. In a study designed to determine the possible effects of lesions of the auditory cortex on visual attention in cats, a Y-maze was constructed. This device eliminates the go, no-go dilemma. The modification of a visually dependent learned task following ablation of nonvisual tempral cortex has been detected with this device. The procedure employed required the animals to move in the direction of a single light when only one was shown, or in either direction when two were shown simultaneously. These animals displayed a weak but statistically significant change in visually dependent escape or avoidance following unilateral temporal ablation.
