Olfactory and motor signals in the hedonic reactivity task and the PIT task. A, An olfactory signal was found in the bilateral piriform cortex during the hedonic reactivity task. B, For display purposes, statistical t maps are shown with a threshold at p < 0.005, uncorrected. A motor signal was found in the right cerebellum and the left thalamus during the PIT task. For display purposes, statistical t maps are shown with a threshold at p < 0.001, uncorrected. Orange overlays indicate brain areas from which fMRI data were acquired in all participants and were thus included in the statistical analysis. Scale bar indicates t statistic.
