| Once fully developed and scaled, it would eliminate the need for invasive brain surgery in many instances, through stimulation of neurons nestled deep within the brain using injected nanoparticles which light up when stimulated by X-rays. | Once fully developed and scaled, it would eliminate the need for invasive brain surgery in many instances, through stimulation of neurons nestled deep within the brain using injected nanoparticles which light up when stimulated by X-rays. |
| Roughly 15 years ago the field of "optogenetics" was developed, which involved genetic modification of specific neurons in the brain so they create a direct channel to the brain and react to external stimuli, namely light. | Roughly 15 years ago the field of "optogenetics" was developed, which involved genetic modification of specific neurons in the brain so they create a direct channel to the brain and react to external stimuli, namely light. |
| There were multiple issues with this method, however, including the tricky business of device implantation and light penetration, but it formed the basis for additional research in a whole new field of non-invasive brain medicine. | There were multiple issues with this method, however, including the tricky business of device implantation and light penetration, but it formed the basis for additional research in a whole new field of non-invasive brain medicine. |
| Current deep brain stimulation techniques typically require invasive and somewhat risky surgery to implant a calibrated pulse generator (kind of like an optic pacemaker for the brain) when drug therapies prove insufficient. | Current deep brain stimulation techniques typically require invasive and somewhat risky surgery to implant a calibrated pulse generator (kind of like an optic pacemaker for the brain) when drug therapies prove insufficient. |
| This subcutaneous implant is then connected to electrodes which are inserted into specific regions of the brain to regulate abnormal impulses. | This subcutaneous implant is then connected to electrodes which are inserted into specific regions of the brain to regulate abnormal impulses. |
| However, with this new treatment, X-rays are able to pass through biological tissues much more efficiently and effectively than light, and with the introduction of the nanoparticles, the light source is already inside the brain, precluding the need for wires or electrodes. | However, with this new treatment, X-rays are able to pass through biological tissues much more efficiently and effectively than light, and with the introduction of the nanoparticles, the light source is already inside the brain, precluding the need for wires or electrodes. |
| "The injected nanoparticles absorb the X-ray energy and convert it into red light, which has significantly greater penetration depth than blue light," said Zhaowei Chen, former CNM postdoctoral fellow. | "The injected nanoparticles absorb the X-ray energy and convert it into red light, which has significantly greater penetration depth than blue light," said Zhaowei Chen, former CNM postdoctoral fellow. |
| Further applications in treating heart conditions or muscle damage are also on the cards further down the line, the researchers say. | Further applications in treating heart conditions or muscle damage are also on the cards further down the line, the researchers say. |

| Dear readers and commenters, | |
| We have implemented a new engine for our comment section. We hope the transition goes smoothly for all of you. Unfortunately, the comments made before the change have been lost due to a technical problem. We are working on restoring them, and hoping to see you fill up the comment section with new ones. You should still be able to log in to comment using your social-media profiles, but if you signed up under an RT profile before, you are invited to create a new profile with the new commenting system. | |
| Sorry for the inconvenience, and looking forward to your future comments, | |
