Doctors Zap the Brains of Awake Brain Surgery Patients to Make Them Laugh and Have Fun

A distinct pathway in the white matter part of the brain known as the cingulum bundle can be used to alleviate stress and anxiety during awake brain surgery, according to new research published today in The Journal of Clinical Investigation. When electrically stimulated, this pathway triggers instantaneous laughter in the patient. But unlike previous experiments, this laughter was also accompanied by positive, uplifting feelings. Preliminary research suggests this technique could be used to calm patients during awake brain surgery, with the authors of the new study, led by neuroscientist Kelly Bijanki from Emory University School of Medicine, saying the findings could also lead to innovative new treatments for depression, anxiety, and chronic pain.
