Comparison of intravital thinned skull and cranial window approaches to study CNS immunobiology in the mouse cortex

摘要

Fluorescent imaging coupled with high-resolution femtosecond pulsed infrared lasers allows for interrogation of cellular interactions deeper in living tissues than ever imagined. Intravital imaging of the central nervous system (CNS) has provided insights into neuronal development, synaptic transmission, and even immune interactions. In this review we will discuss the two most common intravital approaches for studying the cerebral cortex in the live mouse brain for pre-clinical studies, the thinned skull and cranial window techniques, and focus on the advantages and drawbacks of each approach. In addition, we will discuss the use of neuronal physiologic parameters as determinants of successful surgical and imaging preparation.
