Smartphone-Connected Device Can Change Your Mood with a Zap

the MPR take:

With the press of a button on your smartphone, you may soon be able to change your mood with the help of a connected device using a form of transcranial direct current stimulation (TDCS). The startup company Thync has developed a smartphone-controlled device consisting of electrodes that deliver electrical currents targeting specific nerves and muscles below the skin. If the user is seeking an energizing effect, the device is placed just behind the ear; for a calming effect, it is placed on the temple and back of the neck. A prototype study funded by Thync showed that it did have calming effects, but that the results varied and not all individuals had significant reactions. TDCS has not been approved by the Food and Drug Administration (FDA) to treat a specific disease, but it has shown to be promising in treating neuropsychiatric conditions in a range of studies. The company is also in the process of developing technology using ultrasound to treat brain disorders without surgery or medication by affecting areas deep in the brain and targeting precise, minute areas associated with emotions and motivation.

A smartphone-connected device delivers electrical stimulation to nerves in the head. Early next year you should be able to buy a small device that uses electricity to change your mood at the press of a button on your smartphone. The device, from a startup called Thync, currently consists of a set of electrodes connected to a phone.
