Pennsylvania study links brain wiring to cocaine craving and treatment
Edward Coleman, 30, in a quiet Penn study room, undergoes PET scanning while watching addicts smoke crack. Dr Amy Rose Childress reports buclofen may dampen craving, with amygdala activity and dopamine pathways guiding responses. Researchers explore genetic and neurotransmitter factors, twins studies, and drugs like bromocriptine and baclofen as ways to reduce relapse risks.

Mona Lisa Smile Explained by Eye Brain Interaction
Harvard neuroscientist Dr. Margaret Livingstone argues Mona Lisa’s fluctuating smile arises from central and peripheral vision differences. The eye’s fovea reads detail while the surrounding field detects shadows, making the mouth seem to smile as viewers shift gaze. Geena Davis is cited as another example of the Mona Lisa effect.
