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 the ability of brain cells to retain how frequently they send signals to other brain cells. Brain cells that are used for mental exercises (such as languages and math problems) have a tendency to last longer than those that aren't used.
