Regulation of odour-induced emotions results in higher activation of the dorsolateral prefrontal cortex and the anterior insula.

Regulation of odour-induced emotions results in mild lower activation of the amygdala.

Orbitofrontal cortex is less activated during regulation compared to maintain emotions.

Regulation of positive odour-induced emotions results in activation of the supplementary motor area.

Regulation of negative odour-induced emotions results in activation of the posterior cingulate gyrus.
