b'EARLY CAREER RESEARCHER GRANTNThe Role of the Middle Temporal Gyrus in Suicide RiskAudreyana Jagger-Rickels, Ph.D.The Ohio State UniversityMentor: Scott Langenecker, Ph.D. The Ohio State University$140,000We are learning more about the role of the brain with regard to suicide. It is possible that the middle temporal gyrus may play a role in suicide risk. Veterans with and without a history of a suicide attempt will watch an emotional film (measuring emotion disengagement/dissociation) and make self-death associations (measuring negative self-referential processing) while recording brain activity in the middle temporal gyrus. It is hypothesized that the middle temporal gyrus will be overactive in those with a history of a suicide attempt, suggesting it contributes to mechanisms that maintain suicide risk. 30'
