    Area of Science:

    • Neurosurgery
    • Neuroscience
    • Behavioral Science

    Background:

    • The limbic system's role in behavior is complex.
    • Understanding specific pathways is key to targeted interventions.
    • Previous surgical approaches lacked precise anatomical sectoring.

    Purpose of the Study:

    • To present a novel method for sectoring the limbic system.
    • To evaluate the efficacy of this sectoring in surgical procedures.
    • To identify the critical anatomical structures responsible for behavioral modification.

    Main Methods:

    • A new method for dividing the limbic system into sectors was developed.
    • Fifty surgical procedures, including rostral limbotomies (cingulectomy and stereotactic), were analyzed.
    • Results were compared with existing literature on similar procedures.

    Main Results:

    • Rostral limbotomies, via open or stereotactic techniques, yielded comparable outcomes.
    • Stereotactic surgery was associated with a higher rate of recurrence.
    • The interruption of the cingulum, not intersecting systems, correlated with permanent behavioral changes.

    Conclusions:

    • The proposed limbic system sectoring method provides a framework for analysis.
    • Interruption of the cingulum is the primary driver of permanent behavioral modification in these procedures.
    • This finding refines our understanding of the neuroanatomical basis of behavior.
