Colin Powell School psychologist Eric Fertuck and colleagues identify neural signature for Borderline Personality Disorder

A new study has identified a neural signature in the rostro-medial prefrontal cortex that may be linked to Borderline Personality Disorder. Individuals with BPD exhibit reduced activity in this region when rejected, suggesting a hypersensitivity to social rejection. This finding could help develop targeted therapies for the disorder.
