4, Shown here is the nictitating membrane of a masked lapwing as it closes over its eye.

5, It was observed that intraventricular injection of 6-OHDA caused suppression of nictitating membrane conditioning without affecting the unconditioned nictitating membrane response.

6, Neimoidians are tall humanoids, with mottled green-gray skin and smooth noseless faces. A nictitating membrane protects their large red-orange eyes.

7, Objective It is a exploring research on a simple and easy method for establishing the animal model of nictitating membrane conditioned reflex with rabbit.
