Researchers modified current transcranial magnetic stimulation technology to improve its effectiveness for treating depression. The new system, Stanford Accelerated Intelligent Neuromodulation Therapy (SAINT), targeted the subregion between the dorsolateral prefrontal cortex and subgenual cingulate in patients suffering from depression. The treatment delivered rapid relief from depression symptoms for 90% of the test subjects. For 60% of recipients, the effects lasted for more than one-month post-treatment.
Reducing activity in the anterior cingulate decreases empathetic responses in rats. The data suggests an observer shares the emotions of others as it enables them to prepare for danger.
According to researchers, people with anorexia nervosa scored lowest on a test measuring their ability to form insight.
