Unstable non-Lyme-related chronic medical illness over the last 12 months (e.g., cancer, acute myocardial infarction, labile hypertension) b. Any severe skin disorder or skin sensitive area near stimulation locations (e.g. forehead) Neurologic: Any of the following: * History of traumatic brain injury with persistent post-concussive symptoms * History of seizure disorder or recent (\<5 years) seizure history * History of neurosurgery to the head * Chronic headaches or migraines of moderate to severe intensity within the last month * Post stroke deficits that may interfere with assessment * Any progressive neurodegenerative disorder or other neurological disorders that may interfere with assessment at discretion of the investigator.

The use of an occasional dose of these medications is also permitted, but not within 48 hours of neurocognitive study assessments. * Participants whose current daily medication regimen has not been stable for a minimum of 4 weeks prior to final determination of study eligibility * Medical device implanted in the head (such as a Deep Brain Stimulator) or in the neck (such as a Vagus Nerve Stimulator), or metal implants in the head or neck * Inadequate visual or motor skills needed for regular computer use or to operate study equipment, or inability to provide informed consent * Individuals who are pregnant or breastfeeding or planning to become pregnant * Lifestyle Considerations: Participants not willing to refrain from beginning, resuming or increasing non study cognitive training or cognitive enhancing supplements/medications or other therapies that might affect treatment outcome
