Supplementary Material for: Stimulating the human olfactory bulb to evoke smell perception – A case report from awake brain surgery

We describe the single-case of a patient with left-sided frontotemporal astrocytoma who reported perceiving a lemon smell after electrical stimulation in the olfactory bulb. The awake-brain surgery provides a unique opportunity to test how smell percepts are formed at the central level in humans. This information is critical in the emerging field of olfactory implants. The present case emphasizes the significant role of the olfactory bulb as a target structure for the placement of an olfactory prosthesis.
