Pupillary Light Reflex

The Pupillary Light Reflex (PLR) is one of the most powerful windows into brainstem integrity—and this course teaches you how to assess and interpret it with clinical precision. Inside this module, you’ll learn the complete sensory–motor pathway behind the PLR, from retinal input to midbrain integration and parasympathetic output.

We break down each anatomical landmark, the functional significance of direct and consensual responses, and how subtle asymmetries can guide your differential diagnosis. You’ll also learn how to integrate PLR findings into a broader neurological examination and how to use them to support treatment planning within a neuro-fascial framework.

This course is designed for clinicians who want to elevate their neurological skillset with a deeper understanding of mesencephalic function, autonomics, and real-world application—all through the MyoSynaptics lens.
