Figure 4 GABA receptor plasticity in the hippocampus and cingulate cortex. (a) Slides show the dentate gyrus of the hippocampus and cingulate cortex of experimental animals stained for GABA receptors at ×100. GABA receptors were expressed in all regions under view. (b) GABA receptor immunopositive cell counts in the dentate gyrus of the hippocampus (DG) and cingulate cortex (Cg) expressed as a percentage of control. GABA receptor expressing cells were reduced in the dentate gyrus of the hippocampus of ligated animals, whereas it is more in the GABA-treated ligated animals. Cingulate cortex where sensory processing takes place had more GABA receptors expressing cells in ligated and GABA-treated ligated animals compared with control animals.
