One of the stated applications of her Mental Out is memory destruction, so yes, she can, but I doubt she causes destruction like that of Dragon's Breath which destroyed the brain cells. But I don't know the details of the spoiler and I don't even want to know them now.

Of course the scene is canon. The whole Railgun manga is. It's just that Telepathy in Toaru doesn't work like in other series. It makes use of an invisible "wire" made by the user through the manipulation of the vibration of air to create a frequency like an acoustic tube, able to pass the vibrations created by the sound, and passing it to through a connected circuit, sending sound directly to the brain. The only reason why Telepathy didn't work on Touma in vol 6 is that IB was accidentall in the "wire"'s trajectory and negated it. Misaki was able to send a message in Touma's brain because she must have known of that characteristic and moved her remote in a certain angle so that Mental Out's "medium" wasn't accidentally negated like the "wire".
