    Area of Science:

    • Neuroanatomy
    • Human anatomy
    • Brain structures

    Context:

    • The anterior commissure is a white matter tract connecting temporal lobes.
    • Understanding its variability is crucial for neurosurgical procedures and anatomical studies.
    • Previous studies have not fully detailed its precise localization relative to landmarks like Monro's foramen.

    Purpose:

    • To investigate the individual variability in the shape, size, and protrusion of the anterior commissure.
    • To establish a precise method for localizing the anterior commissure's center using ventriculography.
    • To provide anatomical data for neurosurgical planning and research.

    Summary:

    • Variability in anterior commissure shape, section, size, and third ventricle protrusion was assessed in 136 human brains.
    • The center of the anterior commissure was consistently located 3.1 mm below and 2.8 mm anterior to the lower margin of Monro's foramen.
    • Accurate localization on ventriculograms is achievable using the distance from Monro's foramen to the posterior commissure and specific angles.

    Impact:

    • Provides essential anatomical data for neurosurgeons and radiologists.
    • Enhances the precision of neuroimaging interpretation and surgical navigation.
    • Contributes to a deeper understanding of human brain structural variability.
