Near-infrared spectroscopy [PDF]
Journal of Neuroanaesthesiology and Critical Care, 2015 Tissue ischaemia can be a significant contributor to increased morbidity and mortality. Conventional oxygenation monitoring modalities measure systemic oxygenation, but regional tissue oxygenation is not monitored.

Near-Infrared Spectroscopy in Bio-Applications [PDF]
Molecules, 2020 Near-infrared (NIR) spectroscopy occupies a specific spot across the field of bioscience and related disciplines. Its characteristics and application potential differs from infrared (IR) or Raman spectroscopy.

Near infrared spectroscopy [PDF]
Anaesthesia, 1994 The near-infrared portion of the electromagnetic spectrum is located between the visible and mid-range infrared (MIR) sections, roughly 750–2500 nm or 13,333–4000 cm 1 (see Fig. 6.1). It consists (mainly) of overtones and combinations of the bands found in the mid-range infrared region (4000–200 cm ).

Frontiers in Aging Neuroscience, 2022 Brain perfusion declines with aging. Physical exercise represents a low-cost accessible form of intervention to increase cerebral blood flow; however, it remains unclear if exercise-induced amelioration of brain perfusion has any impact on cognition.

Near infrared spectroscopy [PDF]
Anaesthesia, 1996 NIRS is an attractive monitoring technology because it is a noninvasive, real-time, repeatable method that allows for regional assessment of the adequacy of tissue oxygenation. It is able to evaluate the oxygenation state of hemoglobin in tissue and redox state of cyt a1,a3, which reflects the overall activity of oxidative metabolism in the cells.

Speeded near infrared spectroscopy (NIRS) response detection. [PDF]
PLoS ONE, 2010 The hemodynamic response measured by Near Infrared Spectroscopy (NIRS) is temporally delayed from the onset of the underlying neural activity. As a consequence, NIRS based brain-computer-interfaces (BCIs) and neurofeedback learning systems, may have a ...

Detection of the Degree of Natural Mildew of Camellia oleifera Fruit Using Visible/Near Infrared, Mid- and Short-Wave Near Infrared Spectroscopy [PDF]
Shipin Kexue, 2023 This study explored the feasibility of applying visible and near-infrared (400?1 000 nm), and mid- and short-wave near infrared (900?1 700 nm) spectroscopy for detecting Camellia oleifera fruit with different degrees of natural mildew.
