  • Hebbian theory — describes a basic mechanism for synaptic plasticity wherein an increase in synaptic efficacy arises from the presynaptic cell s repeated and persistent stimulation of the postsynaptic cell. Introduced by Donald Hebb in 1949, it is also called… …   Wikipedia

  • Anti-Hebbian learning — In neuroethology and the study of learning, anti Hebbian learning describes a particular class of learning rule by which synaptic plasticity can be controlled. These rules are based on a reversal of Hebb’s postulate, and therefore can be… …   Wikipedia

  • Generalized Hebbian Algorithm — The Generalized Hebbian Algorithm (GHA), also known in the literature as Sanger s rule, is a linear feedforward neural network model for unsupervised learning with applications primarily in principal components analysis. First defined in 1989cite …   Wikipedia

  • Long-term potentiation — (LTP) is a persistent increase in synaptic strength following high frequency stimulation of a chemical synapse. Studies of LTP are often carried out in slices of the hippocampus, an important organ for learning and memory. In such studies,… …   Wikipedia

  • Metaplasticity — is a term originally coined by W.C. Abraham and M.F. Bear to refer to the plasticity of synaptic plasticity. Until that time synaptic plasticity had referred to the plastic nature of individual synapses. However this new form referred to the… …   Wikipedia

  • Ocular dominance column — Ocular dominance columns are stripes of neurons in the visual cortex of certain mammals (including humans) that respond preferentially to input from one eye or the other.[1] The columns span multiple cortical layers, and are laid out in a striped …   Wikipedia

  • Spike timing dependent plasticity — (STDP) is a general term for functional changes in neurons and at synapses that are sensitive to the timing of action potentials in connected neurons. The phrase STDP typically refers to increases or decreases in the efficacy of synaptic… …   Wikipedia
