WebSep 1, 2015 · The fimbria forms the crus of the fornix, which is joined to the opposite fornix across the midline by the commissure of the fornix (hippocampal commissure, psalterium). The body of the fornix (B) at the top of the fornical arch is connected to the inferior surface of the body of the corpus callosum by the septum pellucidum. These fibers start from the ventral part of entorhinal cortex (EC) and contain commissural (EC◀▶Hippocampus) and Perforant path (excitatory EC▶CA1, and inhibitory EC◀▶CA2 ) fibers. They travel along the septotemporal axis of the hippocampus. Perforant path fibers, as the name suggests, perforate subiculum before going to the hippocampus (CA fields) and dentate gyrus.
