In a basement laboratory at Harvard University, a few strands of thin wire mesh are undulating at the bottom of a cup of water, as if in a minuscule ribbon dance. The meshes—about the length of a pen cap—are able to do something unprecedented: once injected into the brain of a living mouse, they can safely stimulate individual neurons and measure the cells' behavior for more than a year.

Electronic brain interfaces like these could someday be crucial for people with neurological diseases such as Parkinson's. The disease causes a group of neurons in one area of the brain to begin dying off, triggering uncontrollable tremors and shakes. Sending targeted electrical jolts to this area can help whip the living neurons back into shape and stop Parkinson's symptoms.

Today people can undergo an electrical treatment called deep brain stimulation. But it has big limitations. It involves implanting rigid, dense electrodes in the brain. That's far from ideal in such a soft organ: after about four weeks, scar tissue begins to build up. The only way to get the electrodes to work through this tissue is to keep upping the voltage used to excite the neurons. That can be dangerous, and sometimes another surgery is required to replace the implant.

If you've had a hankering for a classic, "I for one welcome our ______ overlords," joke, this story is for you.

    , "I for one welcome our ______ overlords," joke, this story is for you.

    "I, for one, [you have to have the commas!] welcome our undulating wire mesh overlords!!"

    Is it just me, or does this not quite work? Only a year? And it does not replace the --victim's-- Patient's free will with an insidious Manchurian Candidate agenda, the way it worked with the Prototype: The Donald. I, for one, welcome our new groping overlord!.
