Neurotech finally ends up in someone's skull

Aneurotech company unveiled a hair powered device that treats depression and is now in the skull of the first patient.

Inner Cosmos's 'digital pill' comprises 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.
