Retrograde Signaling in Long-term Potentiation
As it pertains to long-term potentiation (LTP), retrograde signaling is a hypothesis describing how events underlying LTP may begin in the postsynaptic neuron but be propagated to the presynaptic neuron, even though normal communication across a chemical synapse occurs in a presynaptic to postsynaptic direction. It is used most commonly by those who argue that presynaptic neurons contribute significantly to the expression of LTP.

Famous quotes containing the word long-term:
“Attachment to a baby is a long-term process, not a single, magical moment. The opportunity for bonding at birth may be compared to falling in love—staying in love takes longer and demands more work.”
—T. Berry Brazelton (20th century)
