Neural signatures of glioma progression using implanted neural interfaces

Neural recordings can accurately track glioma progression in vivo, with elevated gamma-band activity consistently linked to tumor growth in mouse models.

• Why it matters: Glioma remains incurable with limited improvements over decades, and understanding neural involvement could open new avenues for monitoring and therapy.
• What they did: Researchers developed a platform for chronic neural recordings in freely behaving mice with gliomas, analyzing neural activity across multiple models and applying machine learning to predict tumor burden.
• The result: Elevated gamma activity predicted tumor progression, and low-dimensional models accurately forecasted individual tumor growth rates, suggesting neural signals could enable real-time monitoring and closed-loop treatments.
