title: Backtalk in neurons.
abstract: A recent paper investigates retrograde transmission from dendrites of the oxytocin neurons of the supraoptic nucleus. Dendrites appear to have release properties different from those of axon terminals, and release appears to be enhanced if intracellular Ca2+ has been previously elevated, suggesting that cells can be 'primed'.
