Final answer:
If a patient is conscious during a procedure where a neurosurgeon electrically stimulates parts of the sensory cortex to locate a tumor, they will most likely experience a sensation of touch or movement in a specific body part.
Step-by-step explanation:
During the procedure where a neurosurgeon electrically stimulates parts of the patient's sensory cortex, if the patient is conscious, they would most likely experience sensation of touch or movement in a specific body part. This is because the sensory cortex is responsible for processing touch and movement sensations. By electrically stimulating this area, the neurosurgeon can identify the location of the tumor based on the patient's sensory responses.
