WebBoth potentiation and depression can happen over a wide spectrum of time. We often divvy it up into short term changes such as on the order of seconds or minutes or long term changes that can be months, years, or even decades. Synaptic neuroplasticity can contribute to both short term and long term potentiation or depression. WebLong-term potentiation is thought to be the molecular event that contributes to learning.
