What is a cranial window?
A cranial window is a glass-covered implant that allows for imaging of the brain while maintaining its integrity.
How long can the cranial window be used for imaging?
The cranial window allows for chronic imaging over periods ranging from minutes to months.
What imaging technique is primarily used?
Two-photon laser microscopy is the primary technique demonstrated in this study.
Who pioneered the cranial window preparation?
Dr. Carl Voda, a Howard Hughes Medical Institute investigator, initially pioneered this preparation.
What are the applications of this technique?
This technique can be used for chronic imaging and other types of imaging, such as optical intrinsic signal imaging.
Is this method applicable to other species?
While this study focuses on rodents, similar techniques may be adapted for other species.
