Network Model With Reduced Metabolic Rate Predicts Spatial Synchrony of Neuronal Activity

Frontiers in Computational Neuroscience, 2021
In a cerebral hypometabolic state, cortical neurons exhibit slow synchronous oscillatory activity with sparse firing. How such a synchronization spatially organizes as the cerebral metabolic rate decreases have not been systemically investigated.

Microbial light-activatable proton pumps as neuronal inhibitors to functionally dissect neuronal networks in C. elegans [PDF]

, 2012
Essentially any behavior in simple and complex animals depends on neuronal network function. Currently, the best-defined system to study neuronal circuits is the nematode Caenorhabditis elegans, as the connectivity of its 302 neurons is exactly known ...

The pulsatory liposome works as a neuronal network (II) [PDF]

INCAS Bulletin
In this paper we consider a unilamellar liposome (lipid vesicle) filled with aqueous solution of an osmotic solute. This liposome is introduced in a hypotonic aqueous medium of large dimensions.

Emergent Dynamics and Spatio Temporal Patterns on Multiplex Neuronal Networks

Frontiers in Computational Neuroscience, 2021
We present a study on the emergence of a variety of spatio temporal patterns among neurons that are connected in a multiplex framework, with neurons on two layers with different functional couplings.

FocusStack and StimServer: a new open source MATLAB toolchain for visual stimulation and analysis of two-photon calcium neuronal imaging data [PDF]

, 2014
Two-photon calcium imaging of neuronal responses is an increasingly accessible technology for probing population responses in cortex at single cell resolution, and with reasonable and improving temporal resolution. However, analysis of two-photon data is

Subsampling effects in neuronal avalanche distributions recorded in vivo [PDF]

, 2009
Background Many systems in nature are characterized by complex behaviour where large cascades of events, or avalanches, unpredictably alternate with periods of little activity. Snow avalanches are an example.

TrpV1 receptor activation rescues neuronal function and network gamma oscillations from Aβ-induced impairment in mouse hippocampus in vitro

eLife, 2018
Amyloid-β peptide (Aβ) forms plaques in Alzheimer’s disease (AD) and is responsible for early cognitive deficits in AD patients. Advancing cognitive decline is accompanied by progressive impairment of cognition-relevant EEG patterns such as gamma ...

Synaptic GABA release prevents GABA transporter type-1 reversal during excessive network activity. [PDF]

, 2015
GABA transporters control extracellular GABA, which regulates the key aspects of neuronal and network behaviour. A prevailing view is that modest neuronal depolarization results in GABA transporter type-1 (GAT-1) reversal causing non-vesicular GABA ...

Impact of Neuronal Membrane Damage on the Local Field Potential in a Large-Scale Simulation of Cerebral Cortex

Frontiers in Neurology, 2017
Within multiscale brain dynamics, the structure–function relationship between cellular changes at a lower scale and coordinated oscillations at a higher scale is not well understood.

Challenges in Reproducibility, Replicability, and Comparability of Computational Models and Tools for Neuronal and Glial Networks, Cells, and Subcellular Structures

Frontiers in Neuroinformatics, 2018
The possibility to replicate and reproduce published research results is one of the biggest challenges in all areas of science. In computational neuroscience, there are thousands of models available.
