Deep brain stimulant necessitate threading electrode deep into the brain — it ’s invasive , but it ’s also an effective room to treat disorders like Parkinson ’s and low . But now scientist have anew wireless mental capacity stimulation technique , which targets the proteins that sense heat and spice .
New Scientist reportson astudy inScience , where researchers interject flyspeck nanoparticles of alloy deeply into the brains of mice . When a magnetic area that continuously switch direction is utilize to these nanoparticles , they give off heat — a well - known effect that has been used to defeat off cancerous cells .
Polina Anikeeva , now at MIT , wanted to see it this could puzzle out in the brain , not to damage nerve cell but to give them a gentle jog . Neurons have TRPV1 receptors , essentially proteins that sense heat . Could the high temperature from the nanoparticles activate nearby nerve cell ? Indeed , experiments in three mice come up applying a magnetic field of view to the nanoparticles made neurons fire .
As with all mice study , this is still a farseeing way from being a discourse in human . Human brain contain more TRPV1 receptors , for example , so targeting prize neuron may be more difficult . But if it does body of work , this technique could be a somewhat less invading and wireless means to carry out thick brain stimulation . [ New Scientist , Science ]
