Fluctuation-driven plasticity allows for flexible rewiring of neuronal assemblies [PDF]

open access: yesarXiv, 2022
Synaptic connections in neuronal circuits are modulated by pre- and post-synaptic spiking activity. Heuristic models of this process of synaptic plasticity can provide excellent fits to results from in-vitro experiments in which pre- and post-synaptic spiking is varied in a controlled fashion.

Modulation of synaptic plasticity by glutamatergic gliotransmission: A modeling study [PDF]

open access: yesNeural Plasticity, volume 2016 (2016), Article ID 7607924, 2016
Glutamatergic gliotransmission, that is the release of glutamate from perisynaptic astrocyte processes in an activity-dependent manner, has emerged as a potentially crucial signaling pathway for regulation of synaptic plasticity, yet its modes of expression and function in vivo remain unclear.

Efficient Design of Triplet Based Spike-Timing Dependent Plasticity [PDF]

open access: yes, 2012
Spike-Timing Dependent Plasticity (STDP) is believed to play an important role in learning and the formation of computational function in the brain. The classical model of STDP which considers the timing between pairs of pre-synaptic and post-synaptic ...

Synaptic Plasticity Dynamics for Deep Continuous Local Learning (DECOLLE)

open access: yesFrontiers in Neuroscience, 2018
A growing body of work underlines striking similarities between biological neural networks and recurrent, binary neural networks. A relatively smaller body of work, however, addresses the similarities between learning dynamics employed in deep artificial

Hippocampal-dependent navigation in head-fixed mice using a floating real-world environment

open access: yesScientific Reports
Head-fixation of mice enables high-resolution monitoring of neuronal activity coupled with precise control of environmental stimuli. Virtual reality can be used to emulate the visual experience of movement during head fixation, but a low inertia floating

Estimating the synaptic current in a multi-conductance AMPA receptor model [PDF]

open access: yes, 2010
A pre-synaptic neuron releases diffusing neurotransmitters such as glutamate that activate post-synaptic receptors. The amplitude of the post-synaptic current, mostly mediated by glutamatergic (AMPARs) receptors, is a fundamental signal that may generate an action potential.

Metabolic constraints on synaptic learning and memory [PDF]

open access: yesJournal of Neurophysiology 122: 1473-1490 (2019), 2019
Dendritic spines, the carriers of long-term memory, occupy a small fraction of cortical space, and yet they are the major consumers of brain metabolic energy. What fraction of this energy goes for synaptic plasticity, correlated with learning and memory?

The Effect of Different Forms of Synaptic Plasticity on Pattern Recognition in the Cerebellar Cortex [PDF]

open access: yes, 2009
“The original publication is available at www.springerlink.com”. Copyright Springer.Many cerebellar learning theories assume that long-term depression (LTD) of synapses between parallel fibres (PFs) and Purkinje cells (PCs) provides the basis for pattern

Synaptic Plasticity Shapes Brain Connectivity: Implications for Network Topology

open access: yesInternational Journal of Molecular Sciences, 2019
Studies of brain network connectivity improved understanding on brain changes and adaptation in response to different pathologies. Synaptic plasticity, the ability of neurons to modify their connections, is involved in brain network remodeling following ...

Multicoding in neural information transfer suggested by mathematical analysis of the frequency-dependent synaptic plasticity in vivo [PDF]

open access: yesarXiv, 2020
Two elements of neural information processing have primarily been proposed: firing rate and spike timing of neurons. In the case of synaptic plasticity, although spike-timing-dependent plasticity (STDP) depending on presynaptic and postsynaptic spike times had been considered the most common rule, recent studies have shown the inhibitory nature of the ...
