Question 3

Their purpose is to rapidly

of interest onto the foveae.

Answer 3

saccades

Question 4

The neurophysiologic pattern of pontine neurons that produces a saccade has been characterized as _________ in type.

This refers to the sudden increase in neuronal firing (the pulse) that is necessary to overcome the inertia and viscous drag of the eyes and move them into
their new position; it is followed by a return to a new baseline firing level (the step)

Answer 4

“pulsestep”

Question 5

to stabilize the image of a moving object on
the foveae, and thus to maintain a continuous clear image
of the object as the object changes position (“smooth
tracking”)

Answer 5

pursuit

side are generated in the i____________
