Timing of medullary late-inspiratory neuron discharges: vagal afferent effects indicate possible off-switch function.

abstract：:1. Many examples of long-term potentiation (LPT) are induced by repetitive electrical stimulation of presynaptic axons. LTP also is induced by direct glutamate iontophoresis (1 M, 1-2 microA, 10 s) onto postsynaptic neurons in hippocampal slices without evoked presynaptic stimulation; this form of LTP is called "ionto...
