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