title: Differential development of Ca2+ dynamics in presynaptic terminal and postsynaptic neuron of the rat auditory synapse.
abstract: Postnatal development of Ca2+ influx and Ca2+ clearance capacity were investigated in the synapse of medial nucleus of the trapezoid body (MNTB) of rat with fura-2 fluorimetry. In contrast to the presynaptic terminal, Ca2+ dynamics does not basically change in the postsynaptic principal neuron developmentally. This differential development of Ca2+ dynamics between pre- and postsynaptic neurons might be crucial for the organized formation and functional maturation of this synapse.
