Researchers from Nankai University said the sensor was inserted intravenously into a goat and received strong and clear electrical signals from the animal’s brain.
“The biggest advantage of this method is that no invasive open brain surgery is required to obtain the electrical signals and the entire operation can be performed in less than two hours,” said lead researcher Duan Feng.
Duan and colleagues used an endovascular brain-computer interface device. Using a robot, they placed a stent through a vein in the goat’s motor cortex. The stent was then expanded to place electrodes on the walls of the blood vessel where neuronal signals could be recorded.
