Pulvinar nuclei, anterior insula, cerebellar crus II, and inferior frontal gyrus are significantly more activated with the photophobia-evoking stimulus (SYMPT) than the control (ASYMPT). Visual cortex and other brain areas were significantly activated in response to the SYMPT condition and the ASYMPT condition. The green represents areas that showed a significant contrast in SYMPT>ASYMPT. No regions were found where a significant contrast was found in ASYMPT>SYMPT. The images are displayed in the patient's native high-resolution space to avoid potential artifacts from spatial transformation to a standard brain atlas. Significant activations and contrasts were thresholded using clusters determined by Z > 3.1 and a (corrected) cluster significance threshold of P = 0.05. A=anterior, BS=brainstem, IFG=inferior frontal gyrus, L=left, P=posterior, R=right.
