Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Exclusion Criteria: Part A Exclusion Criteria: * Fellowship training in neuroanesthesia or neurocritical care. * Participation in EEG-related research or formal EEG training within the past 12 months. * Inability to access or utilize required technology (e.g., computer or tablet with internet access) necessary for completion of digital modules and online assessments. * Any condition (physical, psychological, or cognitive) that, in the opinion of the site investigator, would preclude full participation in study activities or completion of the study protocol. * Known allergy or sensitivity to materials used in EEG electrodes (e.g., adhesives or gels), if applicable. * Non-practicing anesthetic providers (e.g., retired, not currently providing clinical care). Part B Exclusion Criteria: * Is unable to provide legally effective informed consent. * Is scheduled for emergency, cardiac, or neurologic surgery. * Has an American Society of Anesthesiologists (ASA) physical status of IV or greater. * Has a pre-existing diagnosis of dementia, significant cognitive impairment, or other major neurologic disease (e.g., epilepsy, Parkinson's disease). * Has a known allergy to the adhesives or gels used with EEG electrodes. * Has a condition, such as a craniofacial deformity or skin condition on the forehead, that would prevent proper placement or functioning of the EEG monitor. * Currently pregnant.
