Linear contrast between fearful vs. neutral faces under placebo and alcohol conditions. Increased activation to fearful faces is shown in yellow/orange (p < 0.01), while increased activation to neutral faces is shown in blue (p < 0.01). In the placebo condition (top panels), there was greater activation to fearful than to neutral faces in the amygdala (circled in red), parahippocampal gyrus, and visual cortex. These activations were not significant in the alcohol condition (bottom panels). Images copyright 2008, Journal of Neuroscience.
