Q: Which equation best represents the relationship between the volume of cerebrospinal fluid (CSF) in the ventricles ($$V_{CSF}$$), the rate of CSF production ($$R_{prod}$$), and the rate of CSF absorption ($$R_{abs}) $$over time ($$t$$)?

$$V_{CSF} = R_{prod} \times t - R_{abs} \times t$$

Q: Which equation correctly represents the relationship between the number of gyri ($$N_{gyri}$$), sulci ($$N_{sulci}$$), and total surface area ($$A_{total}) of $$the cerebral cortex, assuming each gyri and sulci adds a fixed area $$a$$?

$$A_{total} = (N_{gyri} + N_{sulci}) \times a$$
