blink reflex

Cortical damage, particularly cerebellar lesions, can cause loss of the menace reflex whilst leaving the other blink reflexes, such as the dazzle reflex, unaffected.

The upper facial muscle ME responses could not be innervated by TMS and the low threshold of blink reflexes often interferes with the nature of corticobulbar influences.

These provide information on the width of gaps and on the location of objects in the dark, both by touching objects directly and by sensing air currents; they also trigger protective blink reflexes to protect the eyes from damage.
