Synopsis Of Research:

Investigations in our lab focus on changes in trigeminal blinking produced by disease states such as dry eye. Our studies indicate that the symptoms of the focal dystonia, benign essential blepharospasm, are an exaggeration of the adaptive modifications of trigeminal blinks engendered by dry eye or cornea irritation. Dry eye initiates an increase in reflex blink amplitude, converts the trigeminal reflex blink circuit into an oscillator, increases reflex blink excitability, elevates spontaneous blinking, and creates photophobia. All of the changes reflect sensitization of the trigeminal system. To understand the origins and interactions among these modifications and relate them to the development of benign essential blepharospasm, the lab has projects investigating the neural bases of the modifications associated with dry eye in rodents and humans.
