(A) Response of all cortical areas when gates are closed for all areas (orange), open for visual areas only (green) and open to all areas (blue). Note that areas not involved in visual processing, such as somatosensory areas, are not activated by the input when only visual areas are gated. (B) Spatial activity maps for the delay period corresponding to the three cases in panel A. A weak global coupling (G = 0.2) is used to provide room for the effects of gating (see Materials and Methods), all other parameters as in Figure 2. For the purposes of the gating simulation, ‘visual’ areas were selected according to a recent meta-analysis: V1, V2, V4, MT, LIP, 7a, TEO, TEpd, 8l, 8m, 8B, 46d, 9/46d, and 9/46v. The strength of the gating modulation is gs = 0.38 for the visual-only case, and gs = 0.28 for the all-areas case since it involves more areas (this situation is roughly equivalent to Figure 2).
