The cerebral cortex is not primarily associated with the limbic system. The limbic system is actually a complex set of structures located deeper within the brain, primarily beneath the cerebral cortex. It plays a crucial role in emotional regulation, motivation, and memory.

The correct association within the options provided is the hypothalamus. The hypothalamus is part of the limbic system and is involved in the regulation of various physiological processes, including appetite, temperature, and the sleep-wake cycle. Furthermore, it also plays a vital role in linking the nervous system to the endocrine system via the pituitary gland.

The cerebellum and brainstem are not considered parts of the limbic system. The cerebellum primarily handles motor control and coordination, while the brainstem is responsible for vital life functions such as breathing and heart rate. Therefore, recognizing the role of the hypothalamus in relation to the limbic system highlights its significance in emotional and physiological regulation.
