Brain Images (IMAGE) Optica Caption A new imaging method can capture images of vasculature deep in the brains of mice. A conventional widefield fluorescence image of the mouse brain taken non-invasively in the visible light spectrum is shown on the left, while the non-invasive localization-based DOLI approach operating in the NIR-II spectral window is shown on the right.
