JAW MUSCLE CONNECTION TO YOUR EYE MOVEMENTS?
Yes, you read that right.
A new study published in PLOS ONE unveils a fascinating neural pathway:
Jaw muscle proprioception directly influences your vertical and torsional eye movements.
Researchers have discovered that proprioceptive input from the jaw muscles (through the mesencephalic trigeminal nucleus, or Vme) projects to both:
• The oculomotor nuclei (III/IV), and
• The interstitial nucleus of Cajal (INC) — a key pre-oculomotor hub for vertical-torsional control.
Here’s where it gets even more interesting:
When your head tilts or rolls (like during a vestibulo-ocular reflex or VOR), it’s not just the neck that’s involved. The mandible and jaw muscles are stretched by gravitational forces — and this mechanical change provides sensory input that enhances or modulates VOR, especially for vertical and torsional eye movements.
This may explain:
• Why some patients with jaw dysfunction (TMJ, occlusion issues, postural strain) report visual or vestibular symptoms
• How cervico-ocular reflexes and jaw mechanics may be integrated during complex vestibular responses
• Why treatments involving cranio-cervical sensory integration may improve eye movement stability and reduce symptoms in patients with dizziness, vertical oscillopsia, or VOR dysfunction

At TheFNC, We Explore These Brain-Body Interactions
Using tools like:
• 6DOF vestibular motion platforms
• Infrared oculomotor tracking
• Cervico-mandibular proprioceptive re-integration protocols
• Postural neuromuscular retraining
We help complex patients restore balance, vision, and movement by targeting these under-recognized, yet clinically impactful systems.
