State
Long-term potentiation strengthens a repeatedly used synapse by inserting more receptors; long-term depression weakens an underused one by removing them — the cellular basis of learning and memory.
Show
NMDA receptor activation from rapid repeated stimulation drives AMPA receptor insertion, strengthening that synapse's response.
Watch for
LTD is not simple synaptic failure — pruning weak connections sharpens the relative strength of ones that underwent LTP.
