Structural Synaptic Plasticity Has High Memory Capacity and Can Explain Graded Amnesia, Catastrophic Forgetting, and the Spacing Effect (2014, background): “Previous approaches to memory formation by structural plasticity have also discussed that memories could be encoded in the number of synapses rather than by changing weights of individual synapses [28].”
Memory Capacities for Synaptic and Structural Plasticity (2010, background): “This idea assumes that the network structure can be adapted to the stored data and has close relations to theoretical considerations about structural plasticity (Stepanyants, Hof, & Chklovskii, 2002 ; Poirazi & Mel, 2001 ; Fusi, Drew, & Abbott, 2005 ).”
Correlated neuronal activity and the flow of neural information (2001, background): “A neuron could operate with many such clusters which, if located on ELECTROTONICALLY DISTANT parts of the dendritic tree, could act independently of each other, increasing storage and computational capacit”
Dendritic spikes as a mechanism for cooperative long-term potentiation (2002, background): “via dendritic spikes may therefore lead to the selection of clusters of effective synapses in dendritic domains or branches, a property of dendritic integration that has been proposed to increase the computational power and memory capacity of some neural system”
Consciousness in the universe: a review of the 'Orch OR' theory. (2014, background): “Most scientists and philosophers view consciousness as an emergent property of complex computation among ‘integrate-and-fire’ brain neurons which interconnect and switch at chemically-mediated synapses.”
COORDINATION OF SIZE AND NUMBER OF EXCITATORY AND INHIBITORY SYNAPSES RESULTS IN A BALANCED STRUCTURAL PLASTICITY ALONG MATURE HIPPOCAMPAL CA1 DENDRITES DURING LTP (2011, background): “TBS also elevates intracellular calcium from multiple sources and releases BDNF; events not elicited with tetanic stimulation (Larson et al., 1986; Abraham and Huggett, 1997; Kang et al., 1997;”
Computational subunits in thin dendrites of pyramidal cells (2004, methodology): “The clusteron model was designed in part to demonstrate how a Hebbian learning rule, combined with structural plasticity at the interface between axons and dendrites, can lead similarly activated synapses to aggregate within the same postsynaptic dendritic compartmen”
Activity-dependent structural plasticity. (2009, background): “Thus, sensory deafferentation of cortical tissue can lead to substantial remapping of somato-sensory representations (Pons et al., 1991).”
Fast-spiking, parvalbumin+ GABAergic interneurons: From cellular design to microcircuit function (2014, background): “In pyramidal neurons, the high ratio of Na channels to K channels in dendrites enriches the repertoire of single-neuron computations [∫, sigmoidal threshold mechanism (127)].”
