Responses to the activation of different intranasal trigeminal receptors: Evidence from behavioral, peripheral and central levels.

Aim: There are various receptors that mediate intranasal trigeminal sensations. However, few studies compare the response patterns across different receptor activations.

Methods: We recorded negative mucosal potentials (NMPs) in 24 healthy participants and event-related potentials (ERPs) in 17 participants during exposure to five odors that trigger trigeminal sensations and one olfactory stimulus.
