title: Inhibition by sodium bromide of synaptic potentiation and calcium accumulation in the superior cervical ganglion of rat.
abstract: Electrophysiological data show that sodium bromide (NaBr) inhibits the development of the post-tetanic potentiation in superior cervical ganglia of rat. NaBr treatment also prevented the accumulation of calcium in synaptic vesicles and dendritic vacuoles otherwise seen for some minutes after a tetanizing stimulation. These observations support the notion that the calcium ions entering into pre- and postsynaptic elements play an important role in the genesis of synaptic potentiation.
