Summary
This Review addresses the types and classifications of windows used in optical neuroimaging while describing how to perform in vivo studies using rodent models in combination with other experimental modalities during behavioral tests.
Usefulness & Problems
Why this is useful
A cranial window provides optical access to the rodent brain for in vivo neuroimaging through otherwise opaque skull and skin. The review frames it as a core preparation for longitudinal and multimodal neuroscience experiments.; optical visualization of the CNS through opaque skull and skin; long-term in vivo observation in rodents; combining optical neuroimaging with electrophysiology or optogenetics; longitudinal examination of evolving neural mechanisms

Published Workflows
Objective: Establish chronic optical access to the rodent CNS for longitudinal in vivo neuroimaging, optionally combined with electrophysiology, optogenetics, and behavior-synchronized recording.
Why it works: The review states that optical visualization through opaque skin and bone requires an artificial window and that thinning or removal of skull or spine enables unobstructed long-term in vivo observation. It further notes that window type and materials are chosen according to study objectives and can be designed to accommodate additional modalities.

Stages
- 1.Select window type and materials according to study objective(library_design)
The review states that window types and materials vary depending on the study objectives, implying an upfront design-choice stage before surgery and imaging.
Selection: study objectives determine the type of cranial or spinal window and applied materials
- 2.Prepare optical access by thinning or removing skull or spine and implementing an artificial window(library_build)
The abstract states that an artificial window is primarily required for optical visualization and that thinning or removing portions of skull or spine is necessary for unobstructed long-term in vivo observations.
Selection: create unobstructed optical access to the CNS
- 3.Perform longitudinal in vivo optical imaging(functional_characterization)
The review frames the window as enabling long-term in vivo optical neuroimaging and longitudinal examination of evolving neural mechanisms.
Selection: use the prepared window for unobstructed long-term observation of neural structures and functions
- 4.Integrate additional modalities and behavior-synchronized recording(secondary_characterization)
The abstract explicitly states that windows can be designed to accommodate electrophysiology or optogenetics and that auxiliary apparatuses allow recording in synchrony with behavior across multiple CNS regions.
Selection: combine the window preparation with electrophysiology, optogenetics, or auxiliary apparatuses during behavioral tests

Implementation requires thinning down or removing portions of the skull and selecting window types and materials appropriate to the study objective. The abstract also indicates compatibility with auxiliary apparatuses and other modalities such as electrophysiology or optogenetics.; requires artificial window implantation or skull thinning; material and design choice must match the intended experiment
The abstract does not support a single universally optimal cranial-window design, and it indicates that material and preparation choices vary by objective.; requires thinning or removal of portions of the skull; window type and materials depend on study objectives

Source-stated alternatives
The review contrasts different window types and classifications, including approaches based on thinning versus removing skull. It also discusses multimodal combinations rather than a single fixed preparation.
