The centralized organization of these structures may be sufficiently complex to perform at least some of the functions that brains do. Therefore, when energy and resources are limiting and demands on neural processing are reduced, brains would be expected to get smaller.11 Therefore, if sentience (including the ability to feel pain) is functionally unnecessary for animals such as bivalves and snails, we should expect them to evolve to become non-sentient.
