In order to test an attribute specificity model of prefrontal cortex function, rats with lesions in the prelimbic-infralimbic (PL-IL) or anterior cingulate and precentral (AC-PC) subregions of the medial prefrontal cortex and controls were trained on an object-place paired associate task. Rats with AC-PC lesions acquired the task as readily as controls. In contrast, the PL-IL lesioned rats did not learn the task. Whenever higher order processing is required to solve a task, the data support an attribute-specificity model of prefrontal cortex function in that the PL-IL cortices support both object and place attribute information in a variety of tasks including object-place paired associate learning.
