Figure 1.

Brain areas where activation (as indicated by the BOLD signal) was correlated with stimulus viscosity. Top row, Left, Activations shown bilaterally in a midposterior region of the insular cortex. The sagittal slice shows the anteroposterior extent of the left hemisphere activation marked by the crosshairs. Top row, Right, Scatter plot showing the BOLD signal (percentage change) in this region with respect to viscosity produced by the CMC series. Bottom row, Left, Activations in the anterior insula. The sagittal slice shows the anteroposterior extent of the left hemisphere activation marked by the crosshairs. Bottom row, Right, Scatter plot showing the BOLD signal (percentage change) in this region as a function of oral viscosity produced by the CMC series. The image was thresholded at p < 0.001, uncorrected to show the extent of the activation. R, Right.
