Figure 8. Intercontinental brain-to-brain interface to transfer cortical tactile information.

To test the full potentialities of the BTBI, a brain-to-brain interface to transfer cortical tactile information was established between our laboratory at the IINN-ELS in Brazil and our laboratory at Duke University in the USA. An encoder rat performed a tactile discrimination task at the IINN-ELS. Meanwhile its neuronal activity in S1 was recorded and sent over the internet to our laboratory at Duke University. The sigmoid transformation algorithm was used to transfer the number of action potentials into microstimulation patterns that there were then delivered to the decoder rat's S1 cortex. As the decoder rat made a behavioral response, feedback was sent over the internet to the encoders' chamber back at the IINN-ELS.
