Nature Communications, 2016 STDP is dependent on the timing of pre- and post-synaptic activity. Here, the authors describe a symmetric STDP induction rule at CA3-CA3 synapses, which induces LTP over a broad range of paring intervals.

Coherence resonance and stochastic synchronization in a small-world neural network: An interplay in the presence of spike-timing-dependent plasticity [PDF]
arXiv, 2022 Coherence resonance (CR), stochastic synchronization (SS), and spike-timing-dependent plasticity (STDP) are ubiquitous dynamical processes in biological neural networks. Whether there exists an optimal network and STDP configuration at which CR and SS are both pronounced is a fundamental question of interest that is still elusive.

Topological Effects of Synaptic Time Dependent Plasticity [PDF]
Frontiers in Neural Circuits, March 2010, Volume 4, Article 7, 2008 We show that the local Spike Timing-Dependent Plasticity (STDP) rule has the effect of regulating the trans-synaptic weights of loops of any length within a simulated network of neurons. We show that depending on STDP's polarity, functional loops are formed or eliminated in networks driven to normal spiking conditions by random, partially correlated ...

Brain Inspired Sequences Production by Spiking Neural Networks With Reward-Modulated STDP
Frontiers in Computational Neuroscience, 2021 Understanding and producing embedded sequences according to supra-regular grammars in language has always been considered a high-level cognitive function of human beings, named “syntax barrier” between humans and animals.

Astroglial CB1 Reveal Sex‐Specific Synaptic Effects of Amphetamine
Glia, EarlyView.Astroglial CB1R mediates long‐term synaptic plasticity (LTD) in the Nucleus accumbens. Amphetamine saturates adenosine receptors and blocks LTD in males, but not females. Locomotor effects of amphetamine require astroglial CB1R in males, but not in females.

, 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

Multiple-Step Quantized Triplet STDP Implemented with Memristive Synapse [PDF]
arXiv, 2023 As an extension of the pairwise spike-timing-dependent plasticity (STDP) learning rule, the triplet STDP is provided with greater capability in characterizing the synaptic changes in the biological neural cell. In this work, a novel mixed-signal circuit scheme, called multiple-step quantized triplet STDP, is designed to provide a precise and flexible ...

Alcohol‐sensitive MoS2 optoelectronic synapses for mimicking human‐like visual adaptation
InfoMat, EarlyView.This work demonstrates MoS2 optoelectronic synapses with tunable human‐like visual adaptation to alcohol concentrations, featuring remarkable photo‐induced conductance plasticity for emulating alcohol‐sensitive human visual recognition. By controlling doping levels and applying optoelectronic stimuli, the device can emulate human‐like behaviors such as

Frontiers in Neuroscience, 2013 Long-term potentiation (LTP) and long-term depression (LTD) are generally assumed to be cellular correlates for learning and memory. Different types of LTP induction protocols differing in severity of stimulation can be distinguished in CA1 of the ...

Mathematics, 2023 We consider an unstructured neuron network model composed of excitatory and inhibitory neurons. The synaptic connections are supplied with spike timing-dependent plasticity (STDP). We take the STDP model implemented using a memristor.
