eLife, 2020 Sleep homeostasis manifests as a relative constancy of its daily amount and intensity. Theoretical descriptions define ‘Process S’, a variable with dynamics dependent on global sleep-wake history, and reflected in electroencephalogram (EEG) slow wave ...

Statistical Data Assimilation: Formulation and Examples From Neurobiology
Frontiers in Applied Mathematics and Statistics, 2018 For the Research Topic Data Assimilation and Control: Theory and Applications in Life Sciences we first review the formulation of statistical data assimilation (SDA) and discuss algorithms for exploring variational approximations to the conditional ...

Astrocytes gate Hebbian synaptic plasticity in the striatum
Nature Communications, 2016 Astrocytes regulate synaptic signalling via EAAT glutamate uptake, though whether they play a role in Hebbian plasticity is unknown. Here, the authors find targeting EAAT2 disrupts the emergence of spike timing-dependent plasticity, which highlights the ...

Neural Coding With Bursts—Current State and Future Perspectives
Frontiers in Computational Neuroscience, 2018 Neuronal action potentials or spikes provide a long-range, noise-resistant means of communication between neurons. As point processes single spikes contain little information in themselves, i.e., outside the context of spikes from other neurons. Moreover,

Frontiers in Physics, 2019 Imagined activities could actually be a cognitive basis for creative thinking. However, it is still unknown how they might be related with the architecture of the brain.

Neuronal boost to evolutionary dynamics [PDF]
Interface Focus, 2015 Abstract Standard evolutionary dynamics is limited by the constraints of the genetic system. A central message of evolutionary neurodynamics is that evolutionary dynamics in the brain can happen in a neuronal niche in real time, despite the fact that neurons do not reproduce.

Modular co-organization of functional connectivity and scale-free dynamics in the human brain [PDF]
Network Neuroscience, 2017 Scale-free neuronal dynamics and interareal correlations are emergent characteristics of spontaneous brain activity. How such dynamics and the anatomical patterns of neuronal connectivity are mutually related in brain networks has, however, remained ...

A quantitative model of conserved macroscopic dynamics predicts future motor commands
eLife, 2019 In simple organisms such as Caenorhabditis elegans, whole brain imaging has been performed. Here, we use such recordings to model the nervous system. Our model uses neuronal activity to predict expected time of future motor commands up to 30 s prior to ...

Dynamics of Encoding in a Population of Neurons [PDF]
The Journal of General Physiology, 1972 A simple encoder model, which is a reasonable idealization from known electrophysiological properties, yields a population in which the variation of the firing rate with time is a perfect replica of the shape of the input stimulus. A population of noise-free encoders which depart even slightly from the simple model yield a very much degraded copy of ...
