A Dynamic Spatial Gradient of Hebbian Learning in Dendrites

Abstract: Backpropagating action potentials (bAPs) are an important signal for associative synaptic plasticity in many neurons, but they often fail to fully invade distal dendrites. In this issue of Neuron, Sjöström and Häusser show that distal propagation failure leads to a spatial gradient of Hebbian plasticity in neocortical pyramidal cells. This gradient can be overcome by cooperative distal synaptic input, leading to fundamentally distinct Hebbian learning rules for distal versus proximal synapses.

“…The prediction of the neural network is not just a static map of the external world, but a prediction of the dynamical interactions between the animal and its environment (including other animals). The neural network acquires knowledge of the real world by exploratory action using the Hebbian learning rule [32], which is one of the basic neural mechanisms for learning in animals [7,14,15] and in computational neural network models [16,41,[54][55][56]. Using such Hebbian associative learning mechanism, time-dependent correlation between the sensory input and motor output can be established by the correlation function coefficients embedded in the synaptic weights [78,79].…”

“…However, stability is not always guaranteed by STDP because various types of plasticity exist across different neurons and even at the same neuron, depending on the location of the synapses (Frömke et al, 2005; Bender and Feldman, 2006; Sjöström and Häusser, 2006). Weight dependent STDP has been introduced to solve this issue (Van Rossum et al, 2000; Gütig et al, 2003).…”

“…Note, in many cases only one (D or BP) of the two influences will be active at a synapse (Sjöström and Häusser, 2006;Letzkus et al, 2006, see also commentary by Bender and Feldman (2006)) Detailed equations for the pre-and post-synaptic signals will be given below.…”
