From: Modulating salience network connectivity through olfactory nerve stimulation
A shows the sagittal cross-section of the nasal cavity. The positioning of the electrode head in the olfactory stimulation condition is highlighted in purple. The positioning of the electrode head for the trigeminal stimulation condition is highlighted in turquois. B shows the schematic representation of the timeline of the study. Participants attended two randomized experimental sessions. In each session, they received either olfactory or trigeminal nerve stimulation, followed by an MRI scan. Created with Biorender.com.
