Computational model of extracellular glutamate in the nucleus accumbens predicts neuroadaptations by chronic cocaine
(Elsevier, 2009-02)Chronic cocaine administration causes instability in extracellular glutamate in the nucleus accumbens that is thought to contribute to the vulnerability to relapse. A computational framework was developed to model glutamate ... -
Coregulation of Ion Channel Conductances Preserves Output in a Computational Model of a Crustacean Cardiac Motor Neuron
(Society for Neuroscience, 2010)Similar activity patterns at both neuron and network levels can arise from different combinations of membrane and synaptic conductance values. A strategy by which neurons may preserve their electrical output is via cell ... -
Effects of Turbid Media Optical Properties on Object Visibility in Subsurface Polarization Imaging
(The Optical Society of America, 2006-08)We studied the effectiveness of using polarized illumination and detection to enhance the visibility of targets buried in highly scattering media. The effects of background optical properties including scattering coefficient, ... -
Angular Distribution of Diffuse Reflectance in Biological Tissue
(The Optical Society of America, 2007-09)We measured angular-resolved diffuse reflectance in tissue samples of different anisotropic characteristics. Experimental measurements were compared with theoretical results based on the diffusion approximation. The results ... -
Monte Carlo Model for Studying the Effects of Melanin Concentrations on Retina Light Absorption
(The Optical Society of America, 2008-02)We developed a Monte Carlo model to calculate light absorption in human and mouse retinas. The retina was modeled as a five-layer spherical structure. The effects of melanin concentrations in the retinal pigment epithelium ... -
Effects of Inhomogeneous Myofibril Morphology on Optical Diffraction in Single Muscle Fibers
(The Optical Society of America, 2008-12)Laser diffraction is commonly used in physiological research that explores single muscle fibers. Although variations in sarcomere morphological properties have often been observed, their effects on laser diffraction have ... -

(The Optical Society of America, 2009-05)Propagation of polarized light in skeletal muscle is significantly affected by anisotropic muscle structures. To completely characterize muscle polarization properties, we acquired the whole Mueller matrix images of the ... -
Equi-intensity Distribution of Optical Reflectance in a Fibrous Turbid Medium
(The Optical Society of America, 2010-02)Light propagation in a fibrous anisotropic scattering medium is quite different from that in an isotropic medium. Both the anisotropic diffuse equation (ADE) and the continuous time random walk (CTRW) theory predict that ... -
Correcting Optical-Axis Calculation in Polarization-Sensitive Optical Coherence Tomography
(IEEE Transactions on Biomedical Engineering, 2010-10)Polarization-sensitive optical coherence tomography (PSOCT) has found many applications in imaging birefringence tissue samples. Polarization-sensitive detection is often implemented by utilizing a circularly polarized ... -
Applying the Polarization Memory Effect in Polarization-gated Subsurface Imaging
(The Optical Society of America, 2006-05)Polarization memory is a well established phenomenon occurring when circularly polarized light propagates in turbid media of larger particles. Recent studies have demonstrated that the circularly crosspolarized imaging can ... -
