Bronson: subcortical -> retinocollicular pathway (2-3m), so subcortical to cortical, but:
several cortical information processing pathways so maybe oversimplistic, AND the
psychological abilities in newborns might show islands of cortical functioning.
Schiller: model of overt visual attention. 2 segregated processing streams: broadband
(magnocellular, processes quickly but low resolution and no color), and color-opponent
(parvocellular, slower but high resolution and color).
4 pathways for the control of eye movements:
Pathway
SC From retina to superior Magnocellular Involved in generation of eye
colliculus movements toward simple, easily
discriminable stimuli. Low accuracy
but quick reflex-like responses.
Saccades.
MT V1 (to/not to MT) to Magnocellular and Processes info from broad-band
superior colliculus corticotectal pathway
projections
FEF Eye – brainstem – frontal Converge broad- More detailed and complex analyses
eye fields band and color of visual info, searching in complex
opponent in FEF stimuli
Inhibitory Cortical areas to basal Regulates activity of the SC
ganglia to SN to colliculus
