Exam 7: Perceiving Motion

Emma places her index finger on the far outside edge of one of her eyelids. Then, through her eyelid, she applies gentle pressure to her eye. As she applies pressure, she sees the environment tilt in correspondence with her eye's movement. (A) Explain this change of perception as the eye moves. (B) Does this demonstration support the corollary discharge signal as the stabilizing mechanism during eye movement?

Question 27

Sommer and Wurtz (2006) conducted an experiment where they recorded from single neurons in the frontal eye field (FEF) of monkeys' prefrontal cortex. Their findings offered support for the importance of the corollary discharge signal (CDS) since a flash of light on the _ led to a strong response _ a saccade.
