Our experiments confirm that rats readily learn simple two-choice picture discriminations after hippocampus damage.
In order to test the role of the hippocampus in simple discrimination learning, we performed a series of experiments utilizing a two-choice picture discrimination task. We propose that, although simple discrimination learning may proceed in the absence of the hippocampus, it plays an important role in this type of learning when it is intact. However, a small number of studies have shown that hippocampus damage impairs retention of a previously learned visual discrimination task.
It is generally believed that the hippocampus is not required for simple discrimination learning.
