Which system is a doughnut-shaped set of structures at the border of the brainstem and cerebral hemispheres, associated with emotions and drives, and includes the hippocampus, amygdala, and hypothalamus?

• A. Frontal Lobes
• B. Occipital Lobes
• C. Limbic System
• D. Cerebral Cortex

Answer: (C)

The limbic system is a doughnut-shaped set of structures that sits at the border of the brainstem and the cerebral hemispheres. This network is key for emotions and drives, tying motivation to physiological states. Its important components include the hippocampus, which supports forming and organizing memories; the amygdala, central to processing emotions like fear and arousal; and the hypothalamus, which regulates basic drives and bodily functions such as hunger, thirst, and temperature. Because it integrates emotion, memory, and bodily regulation, this ring-like system is the best fit. The frontal lobes handle planning and decision making, the occipital lobes process vision, and the cerebral cortex refers to the brain’s outer layer involved in many functions but does not name this specific emotional-drive system.
