Persistent tetrodotoxin-resistant (TTX-R) Na+ (Nav1. 9/SCN11A) currents are not normally recorded in vagal afferent neurons (VANs) with 50 mM of extracellular Na+ although the functional expression of this current was observed in the presence of PGE2 or forskolin. However. it is uncertain whether this current can be seen under physiological condition (150 mM Na+). https://www.alarecre.com/NFL-Atlanta-Falcons-Double-Vision-iPhone-13-Pro-MagSafe-Case-p92343/
