Quick Facts
The fornix is a fibrous arch connecting the mammillary bodies, septum and anterior nucleus of the thalamus to the hippocampus. It forms part of the limbic system and is important in the formation of memories and recognition of words and scenes.
The commissure of fornix (aka hippocampal commissure) is a triangular and thin sheet of transverse fibers that connect the hippocampi through the lateral portions of the fornix.
