Neuronium Neuroscience Institute
Quantitative seizure-network analysis for epilepsy surgery planning
Scope

Quantifying the propagation network of focal seizures

Surgical outcomes in focal epilepsy depend on accurate localization of the epileptogenic network. Standard intracranial-EEG review identifies the seizure-onset zone but characterizes propagation incompletely; downstream nodes that contribute to recurrence may remain below the thresholds of conventional detectors.

Neuronium Neuroscience Institute develops a three-step pipeline for epileptogenic-network analysis: localization of the seizure-onset zone from intracranial recordings, identification of energy-dominant network regions that conventional thresholding may attenuate, and projection of both onto the patient's structural connectivity via tractography for surgical review.


Methods

A three-step pipeline from intracranial recordings to surgical representation

Step 01
Seizure-onset zone detection
Z-scored Teager-Kaiser energy and complementary detectors localize the seizure-onset zone from raw intracranial recordings, providing the conventional starting point against which subsequent network analysis is referenced.
Step 02
EDNR identification
Raw and z-scored energy ranks are compared to surface energy-dominant network regions (EDNRs) — contacts whose absolute ictal energy exceeds their normalized expression, and which standard thresholding may attenuate. Hilbert decomposition characterizes the underlying amplitude and frequency profile.
Step 03
Tractography integration
Tractography reconstructs the white matter tracts connecting the seizure-onset zone and EDNRs, integrating the electrographic findings with patient-specific structural connectivity in a single three-dimensional frame for surgical review.

Validation

Multi-center evaluation

The methods have been evaluated on intracranial-EEG recordings from multiple academic medical centers, drawing on both publicly available datasets and de-identified institutional data. Effect sizes are reproducible across institutions, recording modalities, and patient demographics.
