Abstract
Revealing how distributed cortical circuits coordinate behavior in freely moving animals remains a central challenge in systems neuroscience, constrained by limited fields of view, low throughput, and the tethering required by current miniaturized microscopes1-4. Here, we present Airscope, a wireless mesoscope delivering 4 μm lateral resolution across a 6 mm field of view at 12.5 Hz, weighing 1.0 gram. An aspheric-lens design achieves a 2.84× shorter total track length than previous miniaturized microscopes1,2,5,6 while matching the neuron yield of benchtop one-photon mesoscopes; a tailored wireless link supports cable-free calcium imaging from >8,500 neurons per animal (25‑fold increase). Paired with a zero-shot behavior analyzer, Airscope enables cortical imaging across rich behavioral conditions, including room-scale enriched arenas, swimming assays, and multi-organ implantation, with concurrent recording from multiple animals. Using Airscope, we demonstrate versatile applications of untethered cortical imaging across diverse behavioral paradigms. We identify cortical activity patterns across multiple dorsal regions that correlate with behavioral signatures of social dominance, and show dorsal-cortical population activity prospectively decodes competition outcomes across paired animals. We observe reward-location-associated cortical activity patterns during maze exploration, and characterize Granger-causal influence from spinal cord to cortex during fear conditioning, enabled by simultaneous brain-spinal recordings. By uniting large-scale, cellular-resolution recording with unconstrained behavior, Airscope makes naturalistic, multi-animal cortical recording experimentally practical, and provides a broadly accessible technology for systems neuroscience.
The editor's rubric
- Leverage4 / 5
- A general-purpose tool used across several fields (Adam, ResNet, LoRA, next-generation sequencing).
- Magnitude3 / 5
- Large gain: roughly 2x, or a clear new state of the art on a hard, unsaturated problem.
- Evidence3 / 5
- Solid: multiple benchmarks or cohorts, ablations, fair baselines, released code or data.
- Novelty3 / 5
- A genuinely new approach to an open problem.
- Trajectory3 / 5
- A clear path to scale.
- Stakes2 / 5
- Benefits a professional community (practitioners, clinicians, engineers).
Editor’s rationale
Heuristic triage from title and abstract text only, not a reading of the paper. Cues found: method (we propose, we report); breadth (zero/few-shot, programmable); gains (x-fold); novelty (discovery); scale (scalable).
