This proposal aims to study the role that the dorsal prefrontal cortex plays in human social cognition.
Full description
Despite ongoing progress in the understanding of social behavior, little is known about the single-neuronal mechanisms that underlie human social cognition. The investigators will obtain single-neuronal recordings from the prefrontal cortex in participants undergoing clinically planned deep brain stimulation (DBS) electrode placement.
The study population will consist of subjects undergoing planned DBS placement. Prospective participants will be selected for surgery irrespective of their participation in the study. After consenting to the study, the participants will be allowed to withdraw from participation at any time. No control subjects will be used. Instead, each subject will act as their own control based on task performance.
For the study, neuronal recordings will be integrated within planned neurosurgical care and will be obtained from the prefrontal cortex as participants perform a brief behavioral task. During recordings and prior DBS placement, the participants are normally asked to make movements or answer questions based on verbal cues to aid in targeting the correct areas. The participants will be additionally asked to perform a brief linguistic-based task in which scenarios containing social agents are presented to the participants and in which they have to verbally describe/answer questions about them. Following cortical recordings and stimulation, the standard clinical procedure and DBS electrode placement proceeds as planned. The neuronal and behavioral data will then be analyzed off-line.
