Supplementary Figure 1: a. Comparison of the responses during meridian mapping using BOLD and a contrast agent (MION).
From: Parallel, multi-stage processing of colors, faces and shapes in macaque inferior temporal cortex
%Signal change (response to vertical meridian stimulation minus response to horizontal meridian stimulation; see Figure 1) was assessed in two regions of interest, the V1-V2 vertical meridian representation and the PIT/CIT vertical meridian representation. MION substantially enhanced the signal. Data were obtained in the same animal and the BOLD and MION experiments comprises the same number of stimulus runs (N=8). b, Plot showing the C.I.E. xy coordinates of the color stimuli used (left) and the C.I.E. uv coordinates (right).The cardinal axes of DKL color space are shown: L-M and S. C.I.E. Luv space is approximately perceptually uniform. The center point indicates the adaptation point.
