'''Synapse Creatures''' are some of the larger, more intelligent [[Tyranid]] organisms that act as psychic conduits or nodal relays through which a portion of the iron will of the [[Hive Mind]] flows to other lesser members of the hive. It is through [[Synapse]] that the swarms' natural Instinctive Behavior is overridden to the will of the Hive Mind. Some standard Tyranid organisms can be adapted into becoming Synapse Creatures with [[Biomorph]]s. This has been seen with the [[Ravener Prime]], which is equipped with a nodal [[Neuropredatory Crest]].{{Cite ThisFn|5}}
