Webb2 maj 2024 · We make use of Intel’s Loihi chip, which allows the use of a rich family of user-defined on-chip plasticity rules (Davies et al., 2024). We suggest and implement a biologically inspired sequence learning algorithm that makes use of an offline experience replay protocol to consolidate learned information into a separate module, which can … Hebbian theory is a neuropsychology theory claiming that an increase in synaptic efficacy arises from a presynaptic cell's repeated and persistent stimulation of a postsynaptic cell. It is an attempt to explain synaptic plasticity, the adaptation of brain neurons during the learning process. It was introduced by Donald Hebb in his 1949 book The Organization of Behavior. The theory is also called Hebb's rule, Hebb's postulate, and cell assembly theory. Hebb states it as follows: broadstairs beaches mapWebb25 okt. 2024 · The search for biologically faithful synaptic plasticity rules has resulted in a large body of models. They are usually inspired by – and fitted to – experimental data, but they rarely produce neural dynamics that serve complex functions. These failures suggest that current plasticity models are still under-constrained by existing data. Here, we … broadstairs bandstand today
