title: Loss of olfactory function leads to a decrease of trigeminal sensitivity.
abstract: Healthy controls were compared to patients with decreased olfactory sensitivity (n = 32) to investigate interactions between the olfactory and trigeminal systems. Amplitudes of chemo-somatosensory event-related potentials in response to suprathreshold trigeminal stimuli (CO2) were found to be smaller in patients (P < 0.05) indicating a decrease of trigeminally mediated sensations.
