The role of synaptic ion channels in synaptic plasticity
- BiologyEMBO reports
- 2006
The role of synaptic ion channels in learning and memory is reviewed, and the implications and significance of these findings towards deciphering the molecular biology of learning and remember are discussed.
Compartmentalization of Non-Synaptic Plasticity in Neurons at the Subcellular Level
- BiologyNeuroscience and Behavioral Physiology
- 2014
The present review addresses the most important questions of compartmentalization of nonsynaptic plasticity and the effects of non-synaptic plastic changes on the efficiency of the synapses of the neuron concerned.
Spike-Timing Dependent Plasticity Beyond Synapse – Pre- and Post-Synaptic Plasticity of Intrinsic Neuronal Excitability
- BiologyFront. Syn. Neurosci.
- 2010
The induction and expression mechanisms of the induced changes in excitability are described and the functional synergy between synaptic and non-synaptic plasticity and their spatial extent are discussed.
Diverse impact of acute and long-term extracellular proteolytic activity on plasticity of neuronal excitability
- BiologyFront. Cell. Neurosci.
- 2015
A picture emerges whereby both rapid and long-term extracellular proteolysis may influence some aspects of information processing in neurons, such as initiation of action potential, spike frequency adaptation, properties ofaction potential and dendritic backpropagation.

Homeostatic Regulation of Intrinsic Excitability and Synaptic Transmission in a Developing Visual Circuit
- BiologyThe Journal of Neuroscience
- 2007
It is concluded that the coordinated changes between synaptic and intrinsic properties allow developing optic tectal neurons to remain within a stable dynamic range, even as the pattern and strength of visual inputs changes over development, suggesting that homeostatic regulation of intrinsic properties plays a central role in the functional development of neural circuits.

It is suggested here that both spike train attenuation in the dendrite and its modulation by neurotransmitters and electrical activity may have important functional consequences on the magnitude and/or the sign of the synaptic plasticity induced by a Hebbian pairing procedure.

It is shown that exogenous BDNF prevented, and a TrkB-IgG fusion protein reproduced, the change in pyramidal neuron excitability produced by activity blockade, suggesting that BDNF may be the signal controlling a coordinated regulation of synaptic and intrinsic properties aimed at allowing cortical networks to adapt to long-lasting changes in activity.

The evidence for this hypothesis, and the origins of the different kinetic phases of synaptic enhancement, as well as the interpretation of statistical changes in transmitter release and roles played by other factors such as alterations in presynaptic Ca(2+) influx or postsynaptic levels of [Ca(2+)]i are discussed.
Long-Term Potentiation of Intrinsic Excitability at the Mossy Fiber–Granule Cell Synapse of Rat Cerebellum
- BiologyThe Journal of Neuroscience
- 2000
High-frequency stimulation at the mossy fiber–granule cell relay of the cerebellum increased granule cell input resistance and decreased spike threshold, and potentiation of intrinsic excitability was induced by relatively weaker inputs than potentation of synaptic efficacy, whereas with stronger inputs the two aspect of potentiation combined to enhance EPSPs and spike generation.
Beyond parallel fiber LTD: the diversity of synaptic and non-synaptic plasticity in the cerebellum

Recent electrophysiological experiments that have described a rich variety of use-dependent plasticity in cerebellum, including long-term potentiation (LTP) and LTD of excitatory and inhibitory synapses, and persistent modulation of intrinsic neuronal excitability are reviewed.
Selective Presynaptic Propagation of Long-Term Potentiation in Defined Neural Networks
- BiologyThe Journal of Neuroscience
- 2000
It is found that potentiation propagated from the site of induction retrogradely to glutamatergic or GABAergic synapses received by the dendrites of the presynaptic neuron and laterally to those made by its axonal collaterals onto other glutamatorgic cells.
Activity-dependent scaling of quantal amplitude in neocortical neurons
- BiologyNature

A new form of synaptic plasticity is described that increases or decreases the strength of all of a neuron's synaptic inputs as a function of activity, and may help to ensure that firing rates do not become saturated during developmental changes in the number and strength of synaptic inputs.
