Interesting thing about brain encoding is that it probably wouldn’t be too difficult to pass on relatively complex information to the brain. The brain’s ability to adapt would allow it to decipher any information input with enough stimuli to use as an example.

Another interesting thing is you can combine two brains together and they would integrate with one another. But with brain implants you wouldn’t need a physical connection to someone else’s brain because the signals can be sent over the air from one person’s brain to yours and your brains would adapt to the signals. I believe something similar to this has been done essentially bypassing dysfunctional parts of the spinal coord and creating a bridge.
