- For the cellular automaton sometimes called Brain, see OCA:Brian's Brain.
Brain is a c/3 orthogonal spaceship found by David Bell in May 1992. It provides a weak spark at its back which can sometimes be used to perturb objects, such as a glider.

Construction
A 99-glider synthesis of Brain was found by Goldtiger997 in November 2022,[1] solving a long-standing open problem.[2]
A period-690 gun with bounding box 910 × 875 was assembled by Entity Valkyrie in September 2023, using the 99-glider synthesis.[3]
