Figure 2.
A simplified model of the oculomotor system with streamlined neural signals impinging on the SCi that influence saccades. The colors are meant to represent a highly simplified classification of the signal components that inspired the inputs to the model (See Figure 3). They do not represent all signals in each area. Cyan indicates sensory; Blue indicates automated; Red indicates voluntary; and orange indicates inhibitory. DLPFC, dorsolateral prefrontal cortex; SEF, supplementary eye fields; FEF, frontal eye fields; LIP/PEF, lateral intraparietal cortex/parietal eye fields; LGN, lateral geniculate nucleus; SCi, intermediate layers of the Superior colliculus; SCs, superficial layers of the superior colliculus; CD, caudate nucleus; GPe, external globus pallidus; STN, subthalamic nucleus; SNr, substantia nigra pars reticulata.
