WebSeveral examples of neural sensitization include: Electrical or chemical stimulation of the rat hippocampus causes strengthening of synaptic signals, a process known as long-term potentiation or LTP. LTP of AMPA receptors is a potential mechanism underlying memory and learning in the brain. 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. asal hakim

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. This can vary both from person to person and within a single person's activities ... WebMuch of the work on long-lasting synaptic changes between vertebrate neurons (such as long-term potentiation) involves the use of non-physiological experimental stimulation of brain cells. However, some of the physiologically relevant synapse modification mechanisms that have been studied in vertebrate brains do seem to be examples of Hebbian processes.
