In China, a brain implant was installed without opening the skull

Chinese researchers said they were able to implant a sensor into an animal's brain without opening the skull.

which may have potential implications for the treatment of diseases such as Parkinson's disease and paralysis. Discuss

Researchers from Nankai University said the sensor was inserted into a goat through a vein and received strong and clear electrical signals from the animal's brain.

"The biggest advantage of this method isis that invasive open-brain surgery is not required to obtain electrical signals, and the entire operation can be performed in less than two hours,” – said lead researcher Duan Feng.

Duan and colleagues used endovascularbrain-computer interface device. Using a robot, they inserted a stent through a vein into the goat's motor cortex. The stent then expanded to insert electrodes into the walls of the blood vessel, from which neuronal signals could be recorded.
