Area of Science:

Neuroscience
Computational Biology
Developmental Biology

Background:

Multi-electrode arrays (MEAs) are crucial for understanding neural population activity and cybernetic systems.
MEAs enable high-resolution, noninvasive recordings for studying in vitro brain development and dysfunction.

Purpose of the Study:

To introduce a novel deep learning framework, the graph deviation network (GDN), for analyzing neural spiking activity.
To predict network-level alterations associated with autism spectrum disorder (ASD) risk using human forebrain organoids (hFOs).

Main Methods:

Encoding amplitude-modulated spike trains from hFOs as dynamic graphs.
Extracting topological descriptors from these dynamic graphs to identify network organization deviations.
Utilizing a graph deviation network (GDN) for analyzing these graph-based features.

Main Results:

The GDN framework successfully analyzes spiking activity from hFOs.
It detects early signs of dysfunction within 24 hours of exposure to valproic acid (VPA), an ASD risk factor.
The method captures transient millisecond-level events and identifies disruptions in synaptic signaling, efficiency, path length, and connectivity.

Conclusions:

MEA-coupled hFOs serve as predictive platforms for ASD risk assessment.
This approach enables real-time neurotoxicity screening.
The GDN framework provides a powerful tool for analyzing complex neural network dynamics and identifying neurodevelopmental perturbations.
