Figure 7. Respiratory effects produced by the unilateral injection of glutamate in the PPTg in awake rats.

Figure 7

A, histology section showing the location of the unilateral injection of the saline or glutamate into the PPTg. B, histology section showing the location of the unilateral injection of the saline, M‐Atr or kyn into the RTN. C–E, summary data (n = 5–13 rats per group) shows effect of unilateral PPTg injections of saline (Sal; 100 nL) or glutamate (Glut; 10 mm/100 nL) after unilateral injections of saline (50–75 nL), M‐Atr (5 mm/50–75 nL) or kyn (100 mm/50–75 nL) on V T (C); f R (D); and V E (E). Aq, aqueduct mesencephalic; Pn, pontine nucleus; py, pyramidal tract; Sp5, spinal trigeminal nucleus; VII, facial motor nucleus. Scale bar = 1 mm in (B), applied to (A) and (B). *Statistically different from saline + saline. [Color figure can be viewed at wileyonlinelibrary.com]
