Mapping distributed brain function and networks with diffuse optical tomography.
Mapping of human brain function has revolutionized systems neuroscience. However, traditional functional neuroimaging by positron emission tomography or functional magnetic resonance imaging cannotExpand

Atlas-based head modeling and spatial normalization for high-density diffuse optical tomography: In vivo validation against fMRI
TLDR
We demonstrate the feasibility of using atlas-based forward light modeling for accurate HD-DOT image reconstruction and spatial normalization for voxel-wise comparisons across subjects. Expand

Statistical analysis of high density diffuse optical tomography
TLDR
We show the use of event- related protocols and GLM de-convolution analysis in un-mixing multi-stimuli event-related HD-DOT data. Expand

Mapping higher-order brain function and resting-state networks with diffuse optical tomography
TLDR
We present integrative advances in high-density diffuse optical tomography imaging arrays, large field-of-view instrumentation, and anatomical head modeling. Expand

Mapping cortical responses to speech using high-density diffuse optical tomography
TLDR
High-density diffuse optical tomography (HD-DOT) permits presenting speech in a quiet acoustic environment, has excellent temporal resolution relative to the hemodynamic response, and provides noninvasive and metal compatible imaging. Expand

Mapping effective connectivity within cortical networks with diffuse optical tomography
Abstract. Understanding how cortical networks interact in response to task demands is important both for providing insight into the brain’s processing architecture and for managing neurologicalExpand

Stream-Specific Feedback Inputs to the Primate Primary Visual Cortex
TLDR
Using selective viral-mediated labeling of feedback connections arising from specific cytochrome-oxidase stripes of macaque visual area V2, we find that feedback to V1 is organized into parallel streams resembling the reciprocal feedforward pathways. Expand

Imaging speech comprehension in quiet with high density diffuse optical tomography
TLDR
We show that HD-DOT is capable of detecting subtle changes in language network when speech becomes more linguistically challenging. Expand
