The fornix (Latin, “vault” or “arch”) is a C-shaped bundle of fibers (axons) in the brain, and carries signals from the hippocampus to the hypothalamus. The fornix is part of the limbic system. While its exact function and importance in the overall brain physiology is still not entirely clear, it has been demonstrated that surgical transection – the cutting of the fornix along its body – can cause memory loss in humans.
