Neurotransmitter level in MNTB changes with time. (A) GABA level in bilateral MNTB of normal or experimental rats changes with time. (B) Glycine level in bilateral MNTB of normal or experimental rats changes with time. (C) Glutamate level in bilateral MNTB of normal or experimental rats changes with time. a P<0.05 compared to 2 weeks, b P<0.05 compared to 4 weeks, c P<0.05 compared to 1 week. ‘−’ Means no significant difference compared to the other 2 groups. Gly level showed significant increase at 2 weeks bilaterally and even continued to 4 weeks in left MNTB of normal rats (P<0.05). Gly level increased significantly from 1 week to 2 weeks after P12, while GABA and Glu remained stable.
