In vivo two-photon (2P) imaging enables neural circuitry to be repeatedly visualized in both normal conditions and following trauma. This protocol describes how laser-mediated neuronal microlesions can be created in the cerebral cortex using an ultrafast laser without causing a significant inflammatory reaction or compromising the blood-brain barrier. Furthermore, directives are provided for the acute and chronic in vivo imaging of the lesion site, as well as for post-hoc analysis of the lesion site in fixed tissue, which can be correlated with the live imaging phase.
