Final answer:
The putamen is not a part of the limbic system; it is involved in movement regulation and is a component of the basal ganglia.
Step-by-step explanation:
The limbic system is an intricate set of brain structures that deals with emotion regulation, fear responses, motivation, and memory formation. Key parts of the limbic system include the amygdala, which is crucial for experiencing fear and recognizing fearful expressions, the hippocampus, involved in memory processing, and the cingulate gyrus, which helps in managing emotions and pain. From the options given, the putamen is NOT part of the limbic system. The putamen is involved with the regulation of movements and various aspects of learning and is part of the basal ganglia, not the limbic system.
