Final answer:
The central sulcus separates the motor cortex from the sensory cortex.
Step-by-step explanation:
The motor cortex is separated from the sensory cortex by the central sulcus. The central sulcus is a prominent fold in the brain that separates the frontal lobe, which houses the motor cortex, from the parietal lobe, which contains the sensory cortex. The motor cortex is responsible for planning and executing movements, while the sensory cortex processes sensory information.
