1. What is the movement characteristics?Ballistic, rapid, simultaneous, and discrete eye movements between fixation points
2. What is the temporal resolution?Saccades typically complete within 100 milliseconds
3. Why do our eyes do saccades?Saccades help move the sharp part of the retina, called the fovea, onto important places so we can see them clearly. This lets us read, find things, and move around easily.
4. How do our brains control saccades?The frontal eye fields in the front part of the brain plan and start the movement, while the superior colliculus in the midbrain helps make the eye muscles move quickly and accurately.

Ballistic Movement: A movement initiated with high speed, whose trajectory is largely predetermined.
Fovea: The central retinal region providing the sharpest vision, requiring precise saccadic alignment.
