- TMR is injected into the collateral thalamus, and FG is injected into the ipsilateral PBN. The cell body counts were performed for three rats on the ipsilateral side of the FG injection site. Each figure showing the number of cell bodies of one animal was the average of the three rats (10 sections from each rat). The sections were 20 μm thick. FG, TMR and Fos represent all FG-, TMR- and Fos-labeled neurons; data are shown as the mean ± standard deviation (SD)
