Fig. 6.

Effect of CNQX (1 nmol; solid line) on the activity evoked in the ipsilateral digastric muscle by application of EAA receptor agonists to the TMJ region. Line plots illustrate the activity evoked in the ipsilateral digastric muscle as described in Figure 5. Note that co-application of CNQX reduced the magnitude for glutamate- and AMPA-evoked digastric muscle responses without affecting NMDA-evoked digastric muscle responses, indicating that this dose of CNQX was selective for non-NMDA receptors.
