This course provides an in-depth review of techniques and technologies that can be applied to identifying and working within eloquent areas of the brain and performing successful resections of neoplasms and epilepsy foci in adult and pediatric patients. The selection of surgical approaches based on non-invasive monitoring for epilepsy and brain tumors is discussed.

After completing this educational activity, participants should be able to:

• Identify the technologies currently available for pre- and intra-operative brain mapping for tumors and epilepsy.
• Apply brain mapping techniques to daily practice.
• Recognize complication avoidance in epilepsy and brain mapping techniques.
