WebApr 1, 1989 · All rats learned to navigate accurately to a visible platform. Only complete transection of the fornix/fimbria abolished both acquisition and retention of navigation to a hidden platform. Severe impairment of postoperative acquisition was produced by bilateral damage to the medial nucleus accumbens or bilateral damage to the anterior thalamic area. The fibers begin in the hippocampus on each side of the brain as fimbriae; the separate left and right sides are each called the crus of the fornix (plural crura). The bundles of fibers come together in the midline of the brain, forming the body of the fornix. The lower edge of the septum pellucidum (the membrane that separates the lateral ventricles) is attached to the upper face of the fornix body.
