    Radiologists can identify the brain's central sulcus using Talairach's system and sagittal MRI. This method accurately locates brain structures, aiding in functional area mapping.

    Area of Science:

    • Neuroimaging
    • Neuroanatomy
    • Radiology

    Background:

    • Identifying the central sulcus is crucial for understanding brain anatomy and function.
    • Traditional methods may face challenges due to the sulcus's complex and variable course.

    Purpose of the Study:

    • To evaluate the efficacy of Talairach's bicommissural reference system with sagittal MRI for central sulcus identification.
    • To assess the accuracy of this method in localizing functional brain areas.

    Main Methods:

    • Analysis of 50 T-weighted sagittal magnetic resonance imaging (MRI) scans from normal subjects.
    • Utilized contiguous 9 mm thick sections and a standard proportional brain model.
    • Comparison with the co-planar stereotaxic atlas of Talairach and Tournoux.

    Main Results:

    • The central sulcus was successfully identified on all MRI sections.
    • The method proved effective despite the central sulcus's complex lateral projections and variable course.
    • Spatial localization of classical telencephalic functional areas was feasible.

    Conclusions:

    • Talairach's bicommissural reference system combined with sagittal MRI provides a reliable method for central sulcus identification.
    • This approach facilitates accurate localization of brain functional areas, enhancing neuroanatomical studies.
