Results from ICA of PS. One independent component was associated with functional connectivity among parts of amygdala and posterior piriform cortex (z = −16), basal ganglia, thalamus, and insula (z = −4), as well as the secondary somatosensory cortex (z = 20). The signal change for this network (temporal mode) coincided with olfactory stimulation. The default threshold of P > 0.5 was used for testing the alternative hypothesis post statistically. Color bars are given in terms of T-statistic. Left and right in radiological convention.
