Fig. 2

V1 responses to uniformly colored stimuli. (A)-(E) Single-condition images representing the spatial distribution of activities elicited by stimulation with red, yellow, green, blue, and a repeated red, respectively. The dark patches represent activated regions, except for the elongated ones along large blood vessels. The framed regions in panels A-D are enlarged and shown in Fig. 3. (F) A single-condition image derived from control trials in which no stimulus was presented. (G)-(H) Differential images calculated by subtracting panel E from panels A and D, respectively. A, anterior; L, lateral; ΔR/R, band-passed value of the relative change in surface reflectance. Scale bar: 500 μm.
