Interface to the brain: also tested as a wireless version for the first time

For the first time, it has been possible to implement a wireless computer interface to the human brain. Anyone who has ever swapped the network cable for a WLAN connection should know what advantages this can bring in practice.

The previous interfaces of this type were characterized by clearly visible and noticeable cable connections. This makes it possible to carry out tests in laboratory environments, but practical everyday applications are difficult to implement.

With BrainGate, however, there is now a system in which a wire no longer has to be led to the user’s head.

A small transmitter unit is placed on the user’s head, which is connected to an array of electrodes that docks to the movement center in the brain.

Movement impulses will later be transmitted to prostheses via the radio link. People who have lost an arm or a leg, for example, should then be able to regain a good deal of normalcy through an artificial replacement.

No annoying cables in everyday life

The system has already shown its efficiency in clinical trials. Two test persons suffering from paralysis were able to use a tablet well via the BrainGate connection to the brain.

Both when clicking on certain operating elements and when typing with the on-screen keyboard, they were neither slower nor less precise than with a classic system with a cable connection.

And the development went even further. For the first time, a full spectrum of signals from the brain’s movement center is said to have been passed on to an external processing unit.

Ultimately, this should enable patients to cope with their everyday life much more easily. If no cables interfere with normal processes or even pose an additional security risk, this can be all the easier.
