Figure 2
Cortical thickness contrasts between the three smoking categories. Areas in orange–yellow shades represent statistically significant group differences at a falsediscovery rate (FDR)=0.05. Color bar represents FDR q-values. For each panel, the top left brain image represents a view from the top, the bottom left image represents a view from the bottom (the black section is where the brain stem begins), the middle top image represents the left lateral view, the middle bottom image represents the left medial view (the black section is where the hemispheres meet), the top right image represents the right lateral view and the bottom right image represents the right medial view. (a) Areas in which those that never smoked have a thicker cortex than current smokers. (b) Areas in which ex-smokers have a thicker cortex than current smokers. (c) Areas in which those that never smoked have a thicker cortex than ex-smokers. (d) Mean cortical thickness ±1s.e.m. of current, ex- and those that never smoked.
