The muted sense: neurocognitive limitations of olfactory language

Highlights • Naming common odors is astonishingly difficult but mechanisms remain elusive. • We review recent neuroimaging studies that provide mechanistic insight. • Results suggest an odor–language neural system with three main processing stages. • Poor odor naming is explained by a loss of signal...

Description
Summary:Highlights • Naming common odors is astonishingly difficult but mechanisms remain elusive. • We review recent neuroimaging studies that provide mechanistic insight. • Results suggest an odor–language neural system with three main processing stages. • Poor odor naming is explained by a loss of signal fidelity across these stages.
