Our iPSC-based brain model, integrating NANOSTACKS™ and microelectrode arrays (MEA), is enhanced by our proprietary AI model to enable automated seizure liability detection, delivering comprehensive neurotoxicity assessments. This AI-driven platform provides real-time, high-resolution analysis of drug effects on neuronal function, ensuring a standardized and reproducible approach to neurotoxicity screening.Using electrophysiological data from MEA recordings, the AI model was trained to differentiate between seizurogenic and non-seizurogenic compounds, analyze dose-dependent drug effects, and assign a probability score for seizure risk. By leveraging machine learning algorithms, the model detects patterns in network burst frequency, burst duration, and firing rates, enabling a quantitative, predictive assessment of neurotoxicity risks. This high-throughput, human-relevant platform effectively identifies excitatory, inhibitory, and seizurogenic effects, offering a more accurate and scalable alternative for drug safety evaluation.

Figure: Evaluation of seizure liability in neuronal and astrocyte co-culture model: (A) Acetaminophen (Seizure Negative: 1 µM, 3 µM, 10 µM, 30 µM, and 100 µM) exhibited no significant changes in burst duration, burst count, and mean firing rate, confirming the absence of seizure-like effects (B) Kainic Acid (Seizure Positive: 0.1 µM, 0.3 µM, 1 µM, 3 µM, and 10 µM) caused a dose-dependent decrease in burst duration, burst count, and mean firing rate, indicating increased neuronal excitotoxicity and seizure-like activity at higher concentrations.

AI Model for Seizure Prediction and Neurotoxicity Assessment

The AI model analyzes neuronal electrical activity recorded from MEA plates, providing a probabilistic assessment of whether the observed activity patterns within a given time window are consistent with seizure-like activity. The model assigns a probability score reflecting the likelihood of seizure induction at various tested concentrations. This figure illustrates the AI-driven classification of seizure liability based on concentration-dependent neural activity patterns:
 • The number next to each bar represents the count of time segments classified as negative (blue bars) or positive (red bars) for seizure-like activity.
 • The bar length indicates the maximum confidence of the AI model’s prediction among all time segments within each classification.
This analysis highlights the capability of AI-enhanced MEA technology to quantify and predict seizure liability, enabling a high-throughput, standardized, and reproducible approach to neurotoxicity assessment.

The AI model effectively differentiates between seizurogenic and non-seizurogenic compounds, demonstrating its predictive power in assessing seizure liability:
• (A) Acetaminophen (Seizure Negative): Across all tested concentrations (1 µM, 3 µM, 10 µM, 30 µM, and 100 µM), the AI model classified all 53 time segments as seizure-negative, with a 99% probability magnitude, confirming the absence of seizure-like activity.
• (B) Kainic Acid (Seizure Positive): A dose-dependent increase in seizure probability was observed:
• At 0.1 µM, 12 time segments were classified as seizure-negative, while 25 time segments were seizure-positive.
• At 0.3 µM and higher, seizure probability increased significantly, with 37 time segments classified as seizure-positive.This analysis highlights the AI model’s accuracy in quantifying seizure liability, providing a standardized and reproducible probability-based assessment for drug screening.
