>>248>fore towAnyway, the brain is full of electrical signals, so I'd guess that SOME cross-communication would be possible, just as cross-communication is possible through cables (if you've ever put a wireless speaker next to a phone line and heard something that you shouldn't, you'll know what I mean by this).
Here's the thing, though. Everyone is built differently. Even if your brain does pick up something from someone else's brain, I don't think you would be able to interpret it as anything.
Now, if you picked up a signal from someone with the same biological makeup as you, like a twin, things might be different.
