The brain icon was used for the puzzle challenges of Dunwall City Trials and the Time Management achievement. Not sure what ability it may be, but if Strong Arms became one I'm guessing it increases mana and/or power effectiveness.

EDIT: Btw now we have confirmation that Transposition is an upgrade to Doppelgänger. I'm betting Bloodfly Swarm is an upgrade to Shadow Kill.
