Apparently that stuff paralyzes the blink response, and he would have to use some kind of artificial lubricant to keep her eyes from drying out.

For a couple of weeks, it upset the involuntary blinking response and tricked him into biting the inside of his mouth while eating.

(This puff normally causes an automatic blinking response.

Some scientists think that the Interpositus nucleus is the site critical to learning, retaining, and executing the conditioning blink response.

These are distinct from the mechanisms of the more primitive cerebellum, which dominates in the blinking response and receives the input of auditory information directly.

Output from these nuclei control various eye muscles that work synergistically to produce an unconditioned blink response to corneal stimulation (reviewed, Christian & Thompson, 2003).

In the eyeblink conditioning paradigm, a neutral 'conditioned' stimulus such as a tone or a light is repeatedly paired with an 'unconditioned' stimulus, such as an air puff, that elicits a blink response.

Experiments showed that lesions localized either to a specific part of the interpositus nucleus (one of the deep cerebellar nuclei) or to a few specific points in the cerebellar cortex would abolish learning of a correctly timed blink response.
