Abnormal Neural Responses During Reflexive Blinking in Blepharospasm: An <scp>Event‐Related</scp> Functional <scp>MRI</scp> Study

Abstract

Reflexive blinking in blepharospasm is associated with increased activation in the caudate nucleus and sensorimotor cortices, suggesting a loss of inhibition within the sensorimotor corticobasal ganglia network. The association between decreasing neural response during reflexive blinking in the cerebellum with disease duration suggests an adaptive role. © 2020 International Parkinson and Movement Disorder Society.
