Whole-brain optoacoustic imaging of neuronal dynamics

This issue highlights dual positron-emission-tomography–near-infrared probes for the visualization of the trafficking dynamics of a model mRNA vaccine in non-human primates, photoacoustic imaging applied to single-cell intratumoral metabolic heterogeneity and to whole-brain snapshots of neuronal calcium activity in mice, the spectral tracing of glucose metabolism in mice, optoacoustic mesoscopy for biomedicine, and a roadmap for the clinical implementation of optical-imaging biomarkers.

The cover illustrates high-resolution snapshots of neuronal calcium activity across the brain acquired via the optoacoustic imaging of live mice expressing a genetically encoded calcium indicator.
