What is the main goal of phase reversal cortical mapping?

The main goal of phase reversal cortical mapping is specifically aimed at locating the central sulcus in order to identify sensory and motor areas of the brain. This technique involves stimulating the cortex and observing the electrical potentials that reveal where functionally important areas such as the primary motor cortex and primary sensory cortex are situated relative to the central sulcus. By achieving this mapping, clinicians and researchers can better understand the organization of the brain's surface and the relationship of these areas to motor and sensory processing.

The other options do not capture the primary purpose of phase reversal cortical mapping as effectively. For example, while assessing auditory responses is critical in other contexts, phase reversal mapping primarily focuses on motor and sensory regions. Similarly, determining the functioning of peripheral nerves relates more to peripheral neurophysiology rather than cortical mapping. Mapping the spinal cord structure is a separate anatomical focus that does not pertain to the cortical localization achieved through phase reversal techniques.
