There is also evidence for asymmetry in the human olfactory system, although evidence in non-human animal models is lacking. WebbThe insula is also involved in olfaction, although its specific role is less clearly established. In functional neuroimaging studies, the insula is consistently activated by olfactory stimuli, along with other regions including the piriform and orbitofrontal cortex, the amygdala, and the ventral putamen 52.
