Towards the non-invasive imaging of brain networks and functions at high resolution

A new study describes a microscope combining three-photon excitation and adaptive optics capable of high-resolution in vivo imaging of fine neuronal structures in the mouse cortex through the intact skull. The authors demonstrate the use of this platform to guide precise laser-mediated microsurgery and for accurate and sensitive functional calcium imaging.

This paper shows that invasive imaging methods such as the use of an open skull window disrupt spine turnover and brain functions.
