Prefrontal cortex and manipulatory go left-go right differentiation to acoustic directional cues in dogs.

In 20 dogs the manipulatory go left – go right differentiation to acoustic directional cues was elaborated. All dogs received total prefrontal, or dorsolateral (total or partial) or medial (total or partial) cortical ablations. All total ablations markedly affected performance of the task, whereas the partial removals produced moderate or no impairment. Thus, both the dorsolateral and medial prefrontal cortex are involved in this type of differentiation.
