Determination of local optical properties of the rat barrel cortex during neural activation: Monte-Carlo approach to light propagation

Pierre Magistretti, Christian Depeursinge, Pierre Marquet, Stéphane Chamot, Elena Migacheva

Spatially-spectrally-resolved reflectance measurements allow in vivo measuring the optical coefficients of absorption and scattering within the cortical tissue. This method, if applied to neural tissue during enhanced activity, could allow a straightforwar ...

Changes in Hox genes' structure and function during the evolution of the squamate body plan

Denis Duboule

Hox genes are central to the specification of structures along the anterior-posterior body axis, and modifications in their expression have paralleled the emergence of diversity in vertebrate body plans. Here we describe the genomic organization of Hox clu ...

Migraine Aura: Retracting Particle-Like Waves in Weakly Susceptible Cortex

Nouchine Hadjikhani

Cortical spreading depression (SD) has been suggested to underlie migraine aura. Despite a precise match in speed, the spatio-temporal patterns of SD observed in animal cortex and aura symptoms mapped to the cortical surface ordinarily differ in aspects of ...

Multi-axial mechanical properties of human trabecular bone

Liliana Rincon Kohli

In the context of osteoporosis, evaluation of bone fracture risk and improved design of epiphyseal bone implants rely on accurate knowledge of the mechanical properties of trabecular bone. A multi-axial loading chamber was designed, built and applied to ex ...

Epigenetic control of hox genes collinear activation during vertebrate development

Denis Duboule

Hox genes encode transcription factors essential for patterning the anterior to posterior animal body axis. In vertebrates, these genes are arranged in clusters. During development, Hox genes are activated in a time sequence that follows their physical ord ...

Post-Surgical Interval And Lesion Location Within The Limbic Thalamus Determine Extent Of Retrosplenial Cortex Immediate-Early Gene Hypoactivity

Guillaume Poirier

Four experiments examined the disruptive effects of selective lesions in limbic thalamic nuclei on retrosplenial cortex function, as characterized by striking changes in immediate-early gene activity. Major goals were to test the specificity of these retro ...

Predicting Human Resting-State Functional Connectivity from structural Connectivity

Jean-Philippe Thiran, Reto Meuli, Patric Hagmann, Leila Cammoun, Xavier Gigandet, Olaf Sporns

In the cerebral cortex, the activity levels of neuronal populations are continuously fluctuating. When neuronal activity, as measured using functional MRI (fMRI), is temporally coherent across 2 populations, those populations are said to be functionally co ...

Uncoupling time and space in the collinear regulation of Hox genes

Denis Duboule, Jozsef Zakany

During development of the vertebrate body axis, Hox genes are transcribed sequentially, in both time and space, following their relative positions within their genomic clusters. Analyses of animal genomes support the idea that Hox gene clustering is essent ...

Active Contour-Based Segmentation of Head and Neck with Adaptive Atlas Selection

Jean-Philippe Thiran, Meritxell Bach Cuadra, Valérie Duay, Subrahmanyam Venkata Ravi Mohana Sai Gorthi

This paper presents automated segmentation of structures in the Head and Neck (H&N) region, using an active contour-based joint registration and segmentation model. A new atlas selection strategy is also used. Segmentation is performed based on the dense ...

Variation in the shape of pulsed arterial spin labeling kinetic curves across the healthy human brain and its implications for CBF quantification

Daniel Gallichan

Arterial spin labeling (ASL) uses proximally inverted blood water spins as an endogenous contrast agent to measure blood perfusion in tissue. In this work pulsed ASL was used to measure the kinetic curves of cerebral blood flow (CBF) across eight anatomica ...
