Trigeminal Medullary Dorsal Horn Neurons Activated by Nasal Stimulation Coexpress AMPA, NMDA, and NK1 Receptors

Table 2

Percent colocalization of neurotransmitter receptor subunits with Fos-positive neurons. Percentages for each neurotransmitter receptor were determined by dividing the number of colocalized Fos-positive neurons by the total number of Fos-positive neurons present within each location.
