| Popis: | Recently, it has been suggested that diffusion-weighted fMRI could provide a more direct method of observing neuronal activity. In this study, signal originated from brain during hypercapnia and visual stimulation diffusion-weighted fMRI experiments was decomposed into intravascular, fast-diffusion phase, and slow-diffusion phase components. It was concluded that the slow-diffusion phase signal change must reflect the neural activation, although the exact mechanism remains unclear. 16th Scientific Meeting & Exhibition |
