When was the first map of the motor cortex published?

Quick Answer

The motor cortex was mapped in the early 20th century, with major work by Wilder Penfield in the 1930s and 1940s. His famous homunculus map came later in the 20th century.

The Full Story

The motor cortex was mapped in detail through electrical stimulation studies in the 1930s and 1940s, especially by neurosurgeon Wilder Penfield. His work in patients undergoing brain surgery helped show which brain areas control different body movements. The famous sensory and motor “homunculus” diagrams became iconic later, but the underlying cortical mapping was established during this period. This research helped explain how the brain organizes movement and sensation across the body.
