Brains is a natural block. It was originally found in the underground Heck Mini Biome before that was removed. It is currently found in the base of the Ruin, just before the battle with the Heart of the Ruin.
Brains blocks have 2048 health, which translates to a mining time of about 2 minutes and 50 seconds when using a fully upgraded Matter Manipulator. It is the only material that the player can collect and place which is strong enough to survive a meteor hit unshielded.
