Stimulation of the Periaqueductal Gray matter (PAG) and nucleus retroambiguus (nRA) evokes vocalization. nRA modulates the activity of laryngeal motoneurons located in the nucleus ambiguus (nA). We have demonstrated the involvement of rostral and ventral pontine structures in altering laryngeal caliber. A heightened expression of the FOXP2 protein was described in both PAG and pontine regions implicated in cardiorespiratory control.To investigate the interactions between the dlPAG and neurons of the nA assessing the double staining patterns of c-Fos/FOXP2 protein immunoreactivity (c-Fos-ir/FOX
