Long-Term Synaptic Depression MeSH Descriptor Data 2025
A persistent activity-dependent decrease in synaptic efficacy between NEURONS. It typically occurs following repeated low-frequency afferent stimulation, but it can be induced by other methods. Long-term depression appears to play a role in MEMORY.

A persistent activity-dependent decrease in synaptic efficacy between NEURONS. It typically occurs following repeated low-frequency afferent stimulation, but it can be induced by other methods. Long-term depression appears to play a role in MEMORY.
Long-term depression resulting from repeated low-frequency stimulation in only the pathway receiving the induction protocol. It follows induction of LONG-TERM POTENTIATION and reverses it.
