Highlights
- How fUS can be combined with other modalities, including fMRI, electrophysiology, two-photon microscopy and behavioral assays
- Important considerations for longitudinal studies, such as dedicated surgical preparation, lightweight design for unrestrained behavior, and specific signal processing and analysis pipelines
- The simultaneous use of fUS and electrophysiology for macroscopic, mesoscopic, and microscopic measurement of brain activity
- Examples of studies combining fUS with other techniques, including the detailed characterization of brain hemodynamics during sleep and across running episodes on a linear track
