Tsinghua University announces the success of the first clinical trial of wireless minimally invasive brain-computer interface. First patient was a patient who suffered complete spinal cord injury at the cervical spine caused by a car accident and had been in a state of quadriplegia for 14 years.
The internal machine is buried in the skull, and the electrodes are covered in the epidural mater (the dura mater is located between the skull and the cerebral cortex, protecting nerve tissue). It does not damage brain cells.
