Integrated workflows for spiking neuronal network simulations

open access: yesFrontiers in Neuroinformatics, 2013
The increasing availability of computational resources is enabling more detailed, realistic modelling in computational neuroscience, resulting in a shift towards more heterogeneous models of neuronal circuits, and employment of complex experimental ...

Information Encoding in Bursting Spiking Neural Network Modulated by Astrocytes

open access: yesEntropy, 2023
We investigated a mathematical model composed of a spiking neural network (SNN) interacting with astrocytes. We analysed how information content in the form of two-dimensional images can be represented by an SNN in the form of a spatiotemporal spiking ...

Electrophysiological Heterogeneity of Fast-Spiking Interneurons: Chandelier versus Basket Cells [PDF]

open access: yes, 2013
In the prefrontal cortex, parvalbumin-positive inhibitory neurons play a prominent role in the neural circuitry that subserves working memory, and alterations in these neurons contribute to the pathophysiology of schizophrenia.

Core processing neuron‐enabled circuit motifs for neuromorphic computing

open access: yesInfoMat, 2023
Based on brain‐inspired computing frameworks, neuromorphic systems implement large‐scale neural networks in hardware. Although rapid advances have been made in the development of artificial neurons and synapses in recent years, further research is beyond

Unsupervised Spiking Neural Network with Dynamic Learning of Inhibitory Neurons

open access: yesSensors, 2023
A spiking neural network (SNN) is a type of artificial neural network that operates based on discrete spikes to process timing information, similar to the manner in which the human brain processes real-world problems.

Inverse stochastic resonance in networks of spiking neurons. [PDF]

open access: yesPLoS Computational Biology, 2017
Inverse Stochastic Resonance (ISR) is a phenomenon in which the average spiking rate of a neuron exhibits a minimum with respect to noise. ISR has been studied in individual neurons, but here, we investigate ISR in scale-free networks, where the average ...

Resonant neuronal groups

open access: yesPhysics Open, 2022
We create a Spiking Neural Network (SNN) architecture based on transforming the dynamics – Unstable Periodic Orbits (UPOs) – of a chaotic spiking neuron model to Neuronal Groups composed from Resonant Neurons. An input fed to the SNN will activate one of

Synaptic plasticity enables adaptive self-tuning critical networks. [PDF]

open access: yesPLoS Computational Biology, 2015
During rest, the mammalian cortex displays spontaneous neural activity. Spiking of single neurons during rest has been described as irregular and asynchronous.

Systematic configuration and automatic tuning of neuromorphic systems [PDF]

open access: yes, 2011
In the past recent years several research groups have proposed neuromorphic Very Large Scale Integration (VLSI) devices that implement event-based sensors or biophysically realistic networks of spiking neurons.
