Changes in GABABR1b receptor subunit staining 1 month after nerve injury. Figure 5A: Photomicrographs showing qualitative examples of GABABR1b soma staining between control and experimental cortical layers II/III, IV, and V/VI, 1 month after nerve injury: scale bar 5 μm. Figure 5B: Qualitative scatter-plot showing compared GABABR1b staining intensity data for all animals across layer and location one month after nerve injury. Figure 5C: Bar histogram showing the quantified difference in GABABR1b receptor subunit staining between soma and neuropil one month after nerve injury. Figure 5D: Bar histogram showing the quantified difference in GABABR1b receptor subunit staining between cortical layers II/III, IV, and V/VI one month after nerve injury. * = p < .05; ** = p < .01
