Kind: research · Impact: medium

## In brief

- Researchers established patient-derived cortical organoids that recapitulate neuronal network hyperexcitability in benign adult familial myoclonus epilepsy (BAFME).
- Transcriptomic and electrophysiological analyses revealed disease-associated neuronal alterations.
- The study also reports antisense-based work, but the available summary is cut off before its results.

## Why it matters

The study links expanded repeat RNAs to abnormal cortical network activity in a human model of a myoclonus epilepsy, offering a patient-derived system for studying disease mechanisms and testing interventions.
