    Arnab Ghosh
    Neurocritical Care Unit, University College Hospitals, WC1N 3BG, London, UK
    Adv Exp Med Biol 789:21-7. 2013
    ..This unexpected physiological event provides an unusual example of a severe reduction in cerebral oxygen delivery and is the first report correlating change in clinical status with changes in [oxCCO]. ..
  2. doi request reprint Normobaric hyperoxia does not change optical scattering or pathlength but does increase oxidised cytochrome C oxidase concentration in patients with brain injury
    Arnab Ghosh
    Institute of Neurology, University College London, London, UK
    Adv Exp Med Biol 765:67-72. 2013
    ..These results suggest that the measurement of chromophore concentration in the injured brain is not confounded by changes in optical scattering or pathlength and that NBH induces an increase in cerebral aerobic metabolism...
  3. doi request reprint Modelling cerebrovascular reactivity: a novel near-infrared biomarker of cerebral autoregulation?
    David Highton
    University College Hospitals, Queen Square, London, UK
    Adv Exp Med Biol 765:87-93. 2013
    ..Further development of this technique could be used to track CVPR providing targets for individualised management of patients with altered vascular reactivity, minimising secondary neurological insults...
  4. doi request reprint Analysis of the changes in the oxidation of brain tissue cytochrome-c-oxidase in traumatic brain injury patients during hypercapnoea: a broadband NIRS study
    Ilias Tachtsidis
    Biomedical Optics Research Laboratory, Department of Medical Physics and Bioengineering, University College London, Gower Street, London WC1E 6BT, UK
    Adv Exp Med Biol 701:9-14. 2011
    ..Further work using model informed data interpretation may be helpful in understanding the multimodal signals acquired in this heterogeneous patient group...
  5. doi request reprint Dependence on NIRS Source-Detector Spacing of Cytochrome c Oxidase Response to Hypoxia and Hypercapnia in the Adult Brain
    Christina Kolyva
    Department of Medical Physics and Bioengineering, University College London, London, UK
    Adv Exp Med Biol 789:353-9. 2013
    ..We conclude that the Δ[oxCCO] response to hypoxia and hypercapnia appears to be dependent on penetration depth, possibly reflecting differences between the intra- and extracerebral tissue concentration of cytochrome c oxidase. ..
  6. pmc Systematic investigation of changes in oxidized cerebral cytochrome c oxidase concentration during frontal lobe activation in healthy adults
    Christina Kolyva
    Medical Physics and Bioengineering, University College London, London WC1E 6BT, UK
    Biomed Opt Express 3:2550-66. 2012
    ..We conclude that the heterogeneity in the Δ[oxCCO] response is physiological and not induced by confounding factors in the measurements...
