... long-term memory, in the snail and in our brains, synaptic connections become stronger. Scientists had thought ... has a significant role in behavior. When looking at a change in a synaptic connection between a pair of neurons in the Aplysia nervous ...
... , in response to input from the outside world. It is the refinement of these synaptic connections that is the basis of learning and memory, suggesting ... may represent a disruption of the brain's ability to modify its synaptic connections in response to experience. "Taken together ...
... . If forgetting is induced by random fluctuations in the strength of synaptic connections, then free-lunch learning ... here that if forgetting is induced by directional decay in synaptic connectivity, then negative free-lunch ...
