Researchers demonstrated that the hippocampus functions in memory processing by creating lesions in the hippocampi of rats, which resulted in .

Select one:
a. another area of the brain compensating for the damage, enabling the brain compensate for the damage
b. memory impairment on various tasks, such as object recognition and maze running
c. rats that could not complete puzzles even when food was offered as a reward
d. rats that feared the researchers and avoided the cage that was closest to the researcher

b. memory impairment on various tasks, such as object recognition and maze running

Explanation:

The hippocampus is the part of the limbic system which acts as an evaluation center where short-term memory and long-term memory is being processed, and also associated with scanning and spatial map formation necessary for navigation.

Damage to the hippocampi of the brain of rats  from the lesions created in the experiment conducted by researchers, have shown an impairment of memory in rats that has to do with contextual or spatial aspects of experience as the observed in various tasks such as recognition and maze running.
