New eLife study makes whole-brain mean-field models more biologically realistic
AnnaCiaunica · x · 2026-10-27
A study supported by EBRAINS 2.0 and published in eLife extends mean-field models of neuronal populations by incorporating ion exchange between neurons and their surroundings.
- Mean-field models approximate collective brain activity without simulating every neuron in detail, which is computationally expensive
- The new model connects cellular-level ion dynamics to population activity and large-scale brain networks
- Ion concentration changes affect neuronal firing and can contribute to abnormal activity such as epileptic seizures, making this a key biological mechanism for virtual brain simulation
