First brain implant to treat depression is REVEALED

While Elon Musk's Neuralink expects to begin human trials in six months, a neurotech company unveiled a device that treats depression and is now in the skull of the first patient.

Inner Cosmos's 'digital pill' includes two parts: An electrode that sits under the skin of the scalp and the 'prescription pod' that snaps onto the users' hair to power the device.

The implant sends tiny electrical pulses to the brain region affected by depression - the left dorsolateral prefrontal cortex - once daily for 15 minutes.
