Four experiments were conducted with a six unit water T maze learning task. The main brain tissues showing differences between learning and nonlearning animals were the anterior dorsal cortex and the medial ventral cortex. The former probably reflects the motor activity, the swimming, required in the maze the latter, either the learning process or the effects of the stressful situation. The results of these experiments are compared to those obtained earlier in shock avoidance experiments the medial ventral cortex consistently shows differences between learning and nonlearning rats.
