A. Mean (±SEM) percent of PV+ neurons co-expressing c-Fos in EC, SC and IC rats. *Represents a significant difference from EC. B. Mean (±SEM) percent of PV+ neurons co-expressing WFA in EC, SC and IC rats. *Represents a significant difference from EC. #Represents a significant difference from SC. C. Mean (±SEM) percent of WFA+ neurons with low intensity staining and with high intensity staining in EC, SC and IC rats. *Represents significant difference from EC. D. Mean (±SEM) percent of double-labeled WFA+/PV+ neurons co-expressing c-Fos in EC, SC and IC rats. *Represents a significant difference from EC. #Represents a significant difference from SC. E. Photos are representative confocal images of PRV+ neurons co-expressing WFA and c-Fos in EC, SC and IC rats.
