The fate of the inner nose: Odor imagery in patients with olfactory loss

Highlights • We investigated olfactory imagery in patients with olfactory loss, using fMRI. • Typical activation patterns were found in a control group but not in a patient group. • Patients reported significantly lower vividness of olfactory imagery. • Activation in critical areas was correlated wi...

Zusammenfassung:	Highlights • We investigated olfactory imagery in patients with olfactory loss, using fMRI. • Typical activation patterns were found in a control group but not in a patient group. • Patients reported significantly lower vividness of olfactory imagery. • Activation in critical areas was correlated with the duration of olfactory loss. • We conclude that olfactory loss involves difficulties in olfactory imagery.
