Briefings

A Nature article from October 2026 reports the first cortex-wide imaging of naturally behaving mice using 1-gram wireless mesoscopes. This breakthrough enables real-time observation of neural activity without anesthesia, marking a significant shift from traditional invasive techniques. The study provides a foundational dataset for understanding brain function in naturalistic states.

Key points

• Researchers successfully imaged the entire cerebral cortex of naturally behaving mice using 1-gram wireless mesoscopes.
• The imaging occurred without anesthesia, allowing for observation of neural activity in a naturalistic state.

Context

This study represents a major advancement in neuroscience by enabling non-invasive, real-time cortical imaging in freely moving animals, facilitating new research into natural brain function.

Limitations

The study is limited to naturally behaving mice and does not include anesthesia. Data collection occurred in October 2026, and specific neural activity patterns remain to be fully characterized.
