![After crossing the blood-brain barrier, nanoparticles were able to deliver electrical pulses to the brain, potentially eliminating the need for brain-stimulating implant surgery](https://assets.newatlas.com/dims4/default/0d6ac95/2147483647/strip/true/crop/2000x1333+0+0/resize/1440x960!/quality/90/?url=http%3A%2F%2Fnewatlas-brightspot.s3.amazonaws.com%2F9f%2Fe7%2F108390af404cb08f205252ca7f76%2Fdepositphotos-107237330-l.jpg)
The delivery of electrical impulses to different areas of the brain has been used for years to help alleviate the symptoms of Parkinson’s disease, as well as a range of other afflictions. However, the current method of dispatching the zaps involves implanting a pacemaker-like device in the chest and then running wires through holes in the skull to the relevant brain areas. A new technique using piezoelectric nanoparticles that are activated via bursts of ultrasound has shown promise as a wire-free way of stimulating the brain.
