Wavelet coherence analysis of dynamic cerebral autoregulation in neonatal hypoxic–ischemic encephalopathy
(ElsevierDepartment of Bioengineering, The University of Texas at Arlington, 2016-01-25)Cerebral autoregulation represents the physiological mechanisms that keep brain perfusion relatively constant in the face of changes in blood pressure and thus plays an essential role in normal brain function. This study ... -
Transcranial Laser Stimulation Improves Human Cerebral Oxygenation
(Wiley Periodicals, Inc.Department of Bioengineering, The University of Texas at Arlington, 12 January)Transcranial laser stimulation of the brain with near-infrared light is a novel form of non-invasive photobiomodulation or low-level laser therapy (LLLT) that has shown therapeutic potential in a variety of neurological ... -

Quantification and normalization of noise variance with sparsity regularization to enhance diffuse optical tomography
(OSA PublishingDepartment of Bioengineering, The University of Texas at Arlington, 2015-08-01)Conventional reconstruction of diffuse optical tomography (DOT) is based on the Tikhonov regularization and the white Gaussian noise assumption. Consequently, the reconstructed DOT images usually have a low spatial ... -
Prostate cancer detection using combined autofluorescence and light reflectance spectroscopy: ex vivo study of human prostates
(OSA PublishingDepartment of Bioengineering, The University of Texas at Arlington, 2014-05-01)This study was conducted to evaluate the capability of detecting prostate cancer (PCa) using auto-fluorescence lifetime spectroscopy (AFLS) and light reflectance spectroscopy (LRS). AFLS used excitation at 447 nm with ... -
Prefrontal responses to digit span memory phases in patients with post-traumatic stress disorder (PTSD): A functional near infrared spectroscopy study
(Elsevier Inc.Department of Bioengineering, The University of Texas at Arlington, 2014)Neuroimaging studies of post-traumatic stress disorder (PTSD)-related memory impairments have consistently implicated abnormal activities in the frontal and parietal lobes. However, most studies have used block designs ... -
Multiregional functional near-infrared spectroscopy reveals globally symmetrical and frequency-specific patterns of superficial interference
(OSA PublishingDepartment of Bioengineering, The University of Texas at Arlington, 2015-08-01)Linear regression with short source-detector separation channels (S-channels) as references is an efficient way to overcome significant physiological interference from the superficial layer for functional nearinfrared ... -
Improving optical contact for functional near-infrared brain spectroscopy and imaging with brush optodes
(OSA PublisherDepartment of Bioengineering, The University of Texas at Arlington, 2012-05-01)A novel brush optode was designed and demonstrated to overcome poor optical contact with the scalp that can occur during functional near infrared spectroscopy (fNIRS) and imaging due to light obstruction by hair. The ... -

Interplay between up-regulation of cytochrome-c-oxidase and hemoglobin oxygenation induced by near-infrared laser
(NatureDepartment of Bioengineering, The University of Texas at Arlington, 2016-08-03)Photobiomodulation, also known as low-level laser/light therapy (LLLT), refers to the use of red-tonear-infrared light to stimulate cellular functions for physiological or clinical benefits. The mechanism of LLLT is assumed ...
