Exploring how the brain processes social interactions

An Integrated Single-neuronal, Population-, Local Network- and Stimulation-based Prefrontal Investigation of Human Social Cognition

NA · Massachusetts General Hospital · NCT05324579

This study is testing how the brain processes social interactions by recording brain activity from people who are having deep brain stimulation while they perform tasks related to social situations.

What this trial studies

This study investigates the role of the dorsal prefrontal cortex in human social cognition by obtaining single-neuronal recordings from participants undergoing deep brain stimulation (DBS) electrode placement. Participants will perform a brief behavioral task involving social scenarios while their neuronal activity is recorded. Each participant serves as their own control, allowing for a unique analysis of the neuronal mechanisms underlying social behavior. The study aims to enhance our understanding of the neural basis of social cognition through direct observation of brain activity during specific tasks.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who are scheduled for deep brain stimulation surgery and can provide informed consent.

Not a fit: Patients with significant co-morbidities, severe anxiety, or those on CNS-active medications may not benefit from this study.

Why it matters

Potential benefit: If successful, this research could lead to improved understanding and treatment of social cognition disorders.

How similar studies have performed: While studies on social cognition exist, this approach of integrating neuronal recordings during DBS placement is relatively novel and has not been extensively tested.
