Which fissure separates the motor cortex from the sensory cortex?

The fissure that separates the motor cortex from the sensory cortex is known as the Rolandic fissure, which is also commonly referred to as the central sulcus. This structure runs laterally along both hemispheres of the brain, marking the boundary between the precentral gyrus, which is responsible for motor functions, and the postcentral gyrus, which processes sensory information. Understanding the anatomy of the cerebral cortex is crucial in EEG practice as it provides insight into the localization of functions and the interpretation of EEG recordings, especially when analyzing wave patterns related to motor and sensory activities.

The other fissures mentioned play different roles: the lateral fissure separates the temporal lobe from the frontal and parietal lobes, while the calcarine fissure is located in the occipital lobe and is involved with visual processing.
