Abstract:Near-infrared spectroscopy (NIRS) is a medical imaging modality that allows non-invasive estimation of tissue oxygenation and hemodynamics. NIRS has great potential in long-term monitoring of regional cerebral circulation due to its unique combination of excellent temporal resolution, safety and suitability for multimodal measurements, and low cost and portability. Such monitoring can provide valuable information on cerebral oxygenation during voluntary or involuntary cessation of breathing, and on slow changes in spontaneous cerebral activity. However, contribution from extracerebral tissue and motion artefacts hinder interpretation of the measured signals.
