Cranial Part of Parasympathetic Division01:18

Cranial Part of Parasympathetic Division

The cranial part of the parasympathetic division plays a crucial role in regulating the visceral functions of the head and specific structures in the neck, thoracic, and abdominopelvic cavities. Preganglionic fibers of the parasympathetic division exit the brain through cranial nerves III (oculomotor), VII (facial), IX (glossopharyngeal), and X (vagus), delivering parasympathetic output to the respective visceral structures.
The vagus nerve (cranial nerve X) alone accounts for approximately 75...

    Area of Science:

    • Neurology
    • Neurosurgery
    • Autonomic Physiology

    Background:

    • The sphenopalatine ganglion (SPG) plays a crucial role in cerebrovascular autonomic control.
    • SPG dysfunction is implicated in cluster headaches, migraines, stroke, and cerebral vasospasm.

    Purpose of the Study:

    • To explore the potential of the sphenopalatine ganglion (SPG) as a target for neuromodulation.
    • To evaluate SPG stimulation as a minimally invasive therapeutic approach.

    Main Methods:

    • Investigating the accessible pterygopalatine fossa location of the SPG.
    • Developing minimally invasive neuromodulation techniques for SPG targeting.

    Main Results:

    • SPG stimulation presents advantages over ablative SPG procedures due to its reversibility and adjustability.
    • Implantable SPG stimulators are being designed for transient and continuous, on-demand stimulation.

    Conclusions:

    • The sphenopalatine ganglion (SPG) is a promising target for neuromodulation in neurological disorders.
    • Advancements in SPG stimulation techniques are expected to enhance clinical versatility.
