I want to know the answer to the following question:
The suprachiasmatic nucleus is a small part of what part of the brain?
All the background I'm provided with is that "A key component of the arousal system is the suprachiasmatic nucleus (SCN), a tiny part of the hypothalamus located directly above the point at which the optic nerves from the two eyes cross.". Is that enough to answer the question?
Answer: yes
