Functional distinction between ionic and electric ephaptic effects on neuronal firing dynamics

This study presents a computational framework to explore the functional distinction between ionic and electric ephaptic effects on neuronal firing dynamics, showing they regulate population rates and spike timing differently.

An electrodiffusive network model with multicompartmental neurons and synaptic connections

This paper introduces an electrodiffusive network model that tracks intra- and extracellular ion concentrations, electrical potentials, and volume fractions in a biophysically consistent way, showing how ion dynamics affect synaptic strength, spontaneous firing, and glial coupling.

Neural activity induces strongly coupled electro-chemo-mechanical interactions and fluid flow in astrocyte networks and extracellular space - a computational study

Microscopic Quantification of Oxygen Consumption across Cortical Layers

The paper measures oxygen consumption across cortical layers in awake mice and finds a decrease in baseline CMRO2 from layer I to IV, accompanied by increased tissue oxygenation.

Spatially Resolved Estimation of Metabolic Oxygen Consumption From Optical Measurements in Cortex

The paper introduces a new method to estimate spatially resolved CMRO2 from pO2 measurements using the Laplace method, balancing noise reduction and bias.

An electrodiffusive neuron-extracellular-glia model with somatodendritic interactions

The paper introduces an electrodiffusive model of neuron-extracellular-glia interactions to simulate ion dynamics and pathological conditions like spreading depression.

An electrodiffusive, ion conserving Pinsky-Rinzel model with homeostatic mechanisms

The paper introduces an electrodiffusive Pinsky-Rinzel model that accounts for ion concentration dynamics and homeostatic mechanisms, showing its utility in simulating pathological conditions like epilepsy.
