Fast learning with weak synaptic plasticity
WebK.C. Martin, in Encyclopedia of Neuroscience, 2009 Conclusions. Synaptic tagging allows the synapse, rather than the nucleus, to be the unit of long-lasting neuronal plasticity. Studies of the phenomenon of synaptic tagging have not only confirmed its existence but also revealed a number of important characteristics, including cross-tagging, competitive …

Since memories are …
WebJun 22, 2024 · Neuroscientists at the Picower Institute for Learning and Memory at MIT have discovered that when a synapse strengthens, neighboring synapses weaken based on the action of a crucial protein called Arc. The finding provides an explanation of how synaptic strengthening and weakening combine in neurons to produce plasticity. WebSep 30, 2015 · Here we show theoretically that weak synaptic plasticity can, in fact, support fast learning, because of the large number of synapses N onto a cortical neuron. In the …
