Remote Control Nervous System?

Wow. Fascinating and frightening in its implications, all at once. Can’t wait for the military to get their hands on this, weaponize it, and then return it to the police so they can apply it to “crowd control safety devices.”

There is a crowd of protesters. Click. Zzzzzzzzzzz.


Nah. Something like that would never happen.

Invention Regulates Nerve Cells Electronically

A major step toward being able to regulate nerve cells externally with the help of electronics has been taken by researchers at Linköping University and the Karolinska Institute in Sweden. The breakthrough is based on an ion transistor of plastic that can transport ions and charged biomolecules and thereby address and regulate cells.

The invention, which opens new avenues for controlling chemical signals, is being published in the coming issue of the scientific journal Proceedings of the National Academy of Sciences.

When an ion transistor was connected to cultivated nerve cells, it could be used to control the supply of the signal substance acetylcholin locally to the cells. The successful result demonstrates both that the component functions together with biological systems and that even tiny charged biomolecules can be transported without difficulty.

“Since the ion transistor is made of plastic, it can be integrated with other components we are developing. This means we can make use of inexpensive printing processes on flexible materials. We believe ion transistors will play a major role in various applications, such as the controlled delivery of drugs, lab-on-a-chip and sensors,” says Magnus Berggren, Önnesjö professor of organic electronics.
