Journal of Neurophysiology, 2014 Transmitter-mediated homosynaptic potentiation is generally implemented by the same transmitter that mediates the excitatory postsynaptic potentials (EPSPs), e.g., glutamate.

Frontiers in Integrative Neuroscience, 2012 Learning-facilitated plasticity refers to hippocampal synaptic plasticity that is facilitated by novel spatial learning events. Both long-term potentiation (LTP) and long-term depression (LTD) are facilitated by novel hippocampus-dependent learning. This

Tunable Synaptic Plasticity in Crystallized Conjugated Polymer Nanowire Artificial Synapses
Advanced Intelligent Systems, 2020 In biological synapses, short‐term plasticity is important for computation and signal transmission, whereas long‐term plasticity is essential for memory formation.

Portfolio Optimization with Sparse Multivariate Modelling [PDF]
arXiv, 2021 Portfolio optimization approaches inevitably rely on multivariate modeling of markets and the economy. In this paper, we address three sources of error related to the modeling of these complex systems: 1. oversimplifying hypothesis; 2. uncertainties resulting from parameters' sampling error; 3. intrinsic non-stationarity of these systems.

Photoionization cross section in a spherical quantum dot: Effects of some parabolic confining electric potentials [PDF]
Condens. Matter Phys., vol. 20, No. 2, 23703 (2017), 2017 A theoretical investigation of the effects of spatial variation of confining electric potential on photoionization cross section (PCS) in a spherical quantum dot is presented. The potential profiles considered here are the shifted parabolic potential and the inverse lateral shifted parabolic potential compared with the well-studied parabolic potential.

Multivesicular release underlies short term synaptic potentiation independent of release probability change in the supraoptic nucleus. [PDF]
PLoS ONE, 2013 Magnocellular neurons of the supraoptic nucleus receive glutamatergic excitatory inputs that regulate the firing activity and hormone release from these neurons.

Emulating long-term synaptic dynamics with memristive devices [PDF]
, 2016 The potential of memristive devices is often seeing in implementing neuromorphic architectures for achieving brain-like computation. However, the designing procedures do not allow for extended manipulation of the material, unlike CMOS technology, the ...

Altered Short-Term Synaptic Plasticity in Mice Lacking the Metabotropic Glutamate Receptor mGlu7
The Scientific World Journal, 2002 Eight subtypes of metabotropic glutamate (mGlu) receptors have been identified of which two, mGlu5 and mGlu7, are highly expressed at synapses made between CA3 and CA1 pyramidal neurons in the hippocampus.

, 2013 Synfire chains are thought to underlie precisely-timed sequences of spikes observed in various brain regions and across species. How they are formed is not understood. Here we analyze self-organization of synfire chains through the spike-timing dependent
