Relative expression of neurotransmitter receptors mRNA in MNTB. (A) Relative GABAa-R mRNA expression in bilateral MNTB of normal or experimental rats 1w/2w/4w after cochlear ablation (P12). (B) Relative GABAb-R mRNA expression in bilateral MNTB of normal or experimental rats at 1, 2, and 4 weeks after cochlear ablation (P12). (C) Relative Gly-R mRNA expression in bilateral MNTB of normal or experimental rats 1w/2w/4w after cochlear ablation (P12). (D) Relative AMPA mRNA expression in bilateral MNTB of normal or experimental rats at 1, 2, and 4 weeks after cochlear ablation (P12). (E) Relative NMDA mRNA expression in bilateral MNTB of normal or experimental rats at 1, 2, and 4 weeks after cochlear ablation (P12). * P<0.05. There were higher expressions of all 5 receptors in left than right MNTB in experimental rats at 2 weeks (P<0.05), which were decreased at 4 weeks; however, the expression of Gly-R, AMPA, and NMDA were decreased more than the same side of normal rats (P<0.05).
