# Chloride Concentration and Seizure Transition Dynamics

## Overview
Conductance-based neuronal network model studying how intracellular chloride concentration regulates E/I balance and drives seizure evolution through activity-dependent chloride dynamics.

Based on: [Role of chloride concentration in modulating seizure transitions in excitatory and inhibitory networks](https://arxiv.org/abs/2604.15747) (2026-04-17)

## Key Insights
- Intracellular chloride concentration regulates excitation/inhibition balance
- Activity-dependent chloride dynamics drive seizure evolution
- Conductance-based model captures stage transitions
- Mechanistic understanding of seizure progression

## Applications
- Epilepsy modeling
- Seizure prediction
- Drug target identification
- Computational psychiatry

## Abstract
This study investigates how intracellular chloride concentration modulates seizure transitions in excitatory and inhibitory neuronal networks. Using a conductance-based model, we show that activity-dependent chloride dynamics drive seizure evolution through shifts in excitation/inhibition balance, providing mechanistic insights into seizure stage transitions.

## Methodology

### Conductance-Based Model
- Intracellular chloride [Cl-]i as dynamic variable
- Activity-dependent chloride flux through GABA_A receptors
- E/I balance shift drives seizure state transitions
