Explanation:

• Gyri: These are the ridges on the surface of the brain. They do not contain cerebrospinal fluid (CSF).
• Ventricle: The ventricles are cavities within the brain that are filled with CSF. They are important for the production, circulation, and storage of CSF.
• Synapse: A synapse is a junction between two neurons. It is involved in the transmission of nerve impulses and does not contain CSF.
• Sulci: These are the grooves on the surface of the brain. Similar to gyri, they do not contain CSF.
