It’s the first human brain-to-brain interface that facilitates a degree of motor control/intentionality. However it’s not the first brain-to-brain interface. Prof. Christopher James and team have developed and tested a brain-to-brain BCI back in 2009.
His experiment had one person using BCI to transmit thoughts,
translated as a series of binary digits, over the internet to another
person whose computer receives the digits and transmits them to the
second user’s brain through flashing an LED lamp.While attached to an EEG amplifier, the first person would generate
and transmit a series of binary digits, imagining moving their left
arm for zero and their right arm for one. The second person was also
attached to an EEG amplifier and their PC would pick up the stream of
binary digits and flash an LED lamp at two different frequencies, one
for zero and the other one for one. The pattern of the flashing LEDs
is too subtle to be picked by the second person, but it is picked up
by electrodes measuring the visual cortex of the recipient.The encoded information is then extracted from the brain activity of
the second user and the PC can decipher whether a zero or a one was
transmitted.
