SI Results
Contralateral vs. Ipsilateral Saccade Response in Ventral Middle
Superior Temporal and Early Visual Areas in Monkeys. The ventral
tuning for cue but weakly ipsilateral tuning for saccade direction,
whereas the dorsal MST (MSTd) and middle temporal (MT) areas
showed contralateral tuning in both intervals (Fig. S5C). This dis-
tinction may be related to functional differences between the two
subdivisions of MST: MSTd is thought to be specialized for optic
flow analysis related to self-movement perception, whereas MSTv
is involved in processing the motion of discrete objects passing
through the visual field (4). Alternatively, the difference in saccade
tuning may bea consequence ofthe retinotopicorganization: MSTv
mainly represents the peripheral visual field, whereas the area ad-
jacent to MSTd as defined by Nelissen et al. (2) represents the
central field and was included in our delineation of MSTd. The
visual stimulation accompanying saccades can differ for peripheral
and parafoveal receptive fields because of different illumination
