From: When light hurts: Comparative Morphometry of Human Brainstem in Traumatic Photalgia
Tensor-based morphometry of the human brainstem. (A) mTBI without photalgia shows bilateral expansion at the pontine/medulla junction. (B) mTBI with mild photalgia shows local mid-pontine shrinkage, and expansion at the pontine/medulla junction. (C) mTBI with severe photalgia shows marked left mid-pontine shrinkage with expansion above it, and much reduced local expansion at the junction with the midbrain. Arrows indicate the peak locations for the statistical assessments. TNC: trigeminal nuclear complex; VN: vestibular nuclei.
