# Graph Analysis of Neuronal-Culture Connectivity Derived from a Reservoir-Computing Model

## Overview
This skill provides a framework for analyzing neuronal culture connectivity using Reservoir Computing (RC) to extract Intrinsic Connectivity Maps (ICM) from multichannel electrophysiological recordings, followed by graph-theoretical analysis to quantify network dynamics.

## Key Methodology
1. **Reservoir Computing Framework**: Reconstructs network connectivity from MEA recordings by training to extract Intrinsic Connectivity Matrix (ICM)
2. **Graph-Theoretical Analysis**: Interprets ICM as effective adjacency matrix for comprehensive graph analysis including node centrality measures and global network metrics
3. **Validation**: Benchmarks RC-derived connectivity against known ground-truth adjacency matrix through simulation

## Performance Metrics
- ROC AUC up to 0.922
- F1 scores up to 0.796  
- NMWA Pearson correlation up to 0.692

## Applications
- Functional network characterization in neuronal culture systems
- Understanding emergent dynamics in in vitro cortical cultures
- Bridging computational neuroscience with experimental electrophysiology
- Potential applications in neurotoxicity screening and drug discovery
