Journal ArticleDOI

Intrinsic brain activity triggers trigeminal meningeal afferents in a migraine model

Hayrunnisa Bolay, +5 more
- 01 Feb 2002 - 
TL;DR: This work establishes a link between migraine aura and headache by demonstrating that cortical spreading depression activates trigeminovascular afferents and evokes a series of cortical meningeal and brainstem events consistent with the development of headache.
Journal ArticleDOI

Laser speckle contrast imaging in biomedical optics

David A. Boas, +1 more
- 01 Jan 2010 - 
TL;DR: The underlying physics of speckle contrast imaging is reviewed, recent developments to improve the quantitative accuracy of blood flow measures are discussed and applications in neuroscience, dermatology and ophthalmology are reviewed.
Journal ArticleDOI

Dynamic Imaging of Cerebral Blood Flow Using Laser Speckle

Andrew K. Dunn, +3 more
- 01 Mar 2001 - 
TL;DR: Using this method, dynamic images of the relative CBF changes during focal cerebral ischemia and cortical spreading depression were obtained along with electrophysiologic recordings and validated through direct comparison with conventional laser-Doppler measurements.
Journal ArticleDOI

Three dimensional Monte Carlo code for photon migration through complex heterogeneous media including the adult human head

David A. Boas, +3 more
- 11 Feb 2002 - 
TL;DR: A novel Monte Carlo code for photon migration through 3D media with spatially varying optical properties, known as 'tMCimg', is described and can serve as a resource for solving the forward problem for complex 3D structural data obtained by MRI or CT.
Journal ArticleDOI

Ultraflexible nanoelectronic probes form reliable, glial scar–free neural integration

Lan Luan, +12 more
- 01 Feb 2017 - 
TL;DR: In vivo two-photon imaging and postmortem histological analysis revealed seamless, subcellular integration of NET probes with the local cellular and vasculature networks, featuring fully recovered capillaries with an intact blood-brain barrier and complete absence of chronic neuronal degradation and glial scar.
