What is brain mapping?

Brain mapping is a technique used in neuroscience and neurosurgery to identify and interact with various areas of the brain, particularly those critical for specific functions like language and movement. During procedures like awake brain surgery, surgeons use small electrical stimulators to probe different brain regions, observing the effects of stimulation on a patient’s abilities. For instance, stimulating specific parts might temporarily inhibit speech or trigger movements, allowing surgeons to identify and avoid critical areas while addressing issues like seizures or tumors 1.
