What this trial studies

This interventional clinical trial aims to investigate the function of the anterior cingulate cortex (ACC) in patients with refractory epilepsy. Participants will undergo a virtual T-maze task to assess ACC activity during a pre-surgical work-up involving invasive video-EEG monitoring. The study will include two experimental sessions, with the first occurring after informed consent and prior to hospitalization. The findings may provide insights into the ACC's role in task selection and motivation based on reward prediction signals.

Why it matters

Potential benefit: If successful, this study could enhance our understanding of ACC function, potentially leading to improved treatment strategies for refractory epilepsy and related neurological disorders.

How similar studies have gone: While the specific approach of this study is novel, previous research has explored the ACC's role in various neurological conditions, indicating potential for meaningful insights.
