Development of a computerized system for simultaneous visual discrimination in rats.
In order to automate a simultaneous visual discrimination system, a Sutherland jumping-stand box was modified by adding two lateral alleys which connect the feeder compartment with the starting box. By means of a digital interface, this modified box was connected to an Apple IIe PC. A group of rats (n = 8) was trained. All subjects learned. Advantages relevant to the apparatus design, as well as the benefits derived from the automated procedure are discussed.
