Frontal eye field

Looks like

A small area of frontal cortex in front of the motor strip on each side.

What it does

Starts voluntary eye movements, such as looking towards something on purpose.

Keeping it well

Only damaged by stroke or injury; both eyes suddenly fixed towards one side is a sign of stroke.
