Spiral laser scanning photoacoustic microscopy for functional brain imaging in rats.

This research paper discusses the development of a spiral laser scanning photoacoustic microscopy (sLS-PAM) system for functional brain imaging in rats. The aim of the study was to create a high-resolution, fast frame-rate, and wide field-of-view (FOV) PAM system that can capture hemodynamic changes in the brain. The sLS-PAM system was able to image cerebral hemodynamics in response to whisker and electrical stimulation, as well as vascular imaging of a modeled brain injury. The researchers believe that this simple-to-implement PAM system could become an affordable functional neuroimaging tool for researchers. [Extracted from the article]
