Eye reduction versus hyperplasia and ectopic eye induction by the inhibition and the activation of Notch signaling driven by ey-GAL4. (a) Wild-type fly head. (b) UAS-Ndn ey-GAL4 fly lacking eye. (c) UAS-Nact ey-GAL4 fly shows hyperplasia of the eye and an ectopic eye on the rostral membrane of the head.
