### Answering the Question

The structure that regulates the body's internal states is the **hypothalamus**.

### Explanation

1. **Thalamus**: Primarily responsible for relaying sensory and motor signals to the cerebral cortex and is also involved in the regulation of consciousness, sleep, and alertness.

2. **Hypothalamus**: This small, but crucial, part of the brain is integral in maintaining homeostasis by regulating body temperature, hunger, thirst, fatigue, sleep, and circadian cycles. It directly influences the endocrine system and the autonomic nervous system, making it key in controlling both internal states and physiological responses.

3. **Limbic System**: This structure is more associated with emotions, memories, and certain aspects of behavior rather than direct regulation of internal states.

4. **Basal Ganglia**: Primarily involved in motor control and learning, it does not directly regulate internal states.

### Conclusion

Thus, the correct answer is **hypothalamus**, as it plays a fundamental role in regulating various internal states of the body.
