The diagram shows schematically the main brain structures for the
control of saccadic eye movements, the corresponding functional
aspects, and the type of saccade associated with it. The prefrontal
structures (pf) and supplementary eye fields (sef) are associated with
delayed and memory guided saccades. The lines represent functional
influences, not necessarily anatomical connections. The arrows may
represent excitatory or inhibitory actions. For example, "fixation"
inhibits the saccade system.
