On the bottom until it's adjusted to your lighting. After that depends on what type of brain, most people leave open brains (lobos, trachys) on the sand but they can be put on the rocks as long as they don't expand and hit rock which could damage them, closed brains like favias will like rockwork to grow over. Trachys seem to adapt to more lighting the best and some favias the worst IME. It depends on the coral though.

lower flow (not a deadzone though) and lower light are best which typically means the lower side of the tank. With open brains just make sure they don't get covered in sand when placed on the sandbed. I had a tiger pistol that liked to spite me occasionally blasting sand over my open brain.
