Left Fornix of Forebrain (Fornix sinister)
Educational content only — not medical advice.
Anatomy
The left fornix is a major C-shaped projection tract of the limbic system, connecting the hippocampus in the temporal lobe to the mammillary body of the hypothalamus. Ascending as the crus beneath the corpus callosum, merging into the body, and diving anteriorly as the column, it represents the primary efferent conduit of the Papez circuit essential for declarative memory formation.
Clinical notes
Bilateral transaction or injury to the columns of the fornix during third ventricle colloid cyst resection causes profound permanent anterograde amnesia.
