Development of glycine receptor distribution in the lateral superior olive of the gerbil

The concentration and relative distribution of glycine receptors were
determined for the gerbil lateral superior olive at several postnatal ages.
Quantitative autoradiographic techniques revealed significant 3H-
strychnine binding to all regions of the nucleus from 4 to 90 d. However,
during the first 20 d, a nonuniform distribution of binding emerged, such
that the greatest concentration of receptor was found in the high-frequency
region of the nucleus. An analysis of neuron packing density showed an
approximate 2-fold distribution along the same axis at all ages. This
evidence is consistent with an elimination of glycine receptors in the
ventral region of the lateral superior olive as maturation progresses.
