Open AccessEFhd2/Swiprosin-1 is a common genetic determinator for sensation-seeking/low anxiety and alcohol addiction
In many societies, the majority of adults regularly consume alcohol. However, only a small proportion develops alcohol addiction. Individuals at risk often show a high sensation-seeking/low-anxiety behavioural...

The Arf6 activator Efa6/PSD3 confers regional specificity and modulates ethanol consumption in Drosophila and humans
Ubiquitously expressed genes have been implicated in a variety of specific behaviors, including responses to ethanol. However, the mechanisms that confer this behavioral specificity have remained elusive. Prev...

Open AccessDisentangling the autism−anxiety overlap: fMRI of reward processing in a community-based longitudinal study
Up to 40% of youth with autism spectrum disorder (ASD) also suffer from anxiety, and this comorbidity is linked with significant functional impairment. However, the mechanisms of this overlap are poorly unders...

Genomic architecture of human neuroanatomical diversity
Human brain anatomy is strikingly diverse and highly inheritable: genetic factors may explain up to 80% of its variability. Prior studies have tried to detect genetic variants with a large effect on neuroanato...

Using 3D Non Rigid FFD-Based Method to Register post mortem 3D Histological Data and in vivo MRI of a Baboon Brain
The aim of this study is to propose a protocol allowing to merge informations acquired in vivo (MRI) and post mortem (histology). Departing from the 3-D histological volume and MRI, we first estimated a rigid ...

Inferring the Brain Connectivity from MR Diffusion Tensor Data
Magnetic resonance diffusion tensor imaging (DTI) has become an established research tool for the investigation of tissue structure and orientation. In this paper, we are interested in the connectivity induced...

Regularization of MR diffusion tensor maps for tracking brain white matter bundles
We propose a new way for tracking brain white matter fiber bundles in diffusion tensor maps. Diffusion maps provide information about mobility of water protons in different directions. Assuming that diffusion ...

Robust brain segmentation using histogram scale-space analysis and mathematical morphology
In this paper, we propose a robust fully non-supervised method dedicated to the segmentation of the brain in T1-weighted MR images. The first step consists in the analysis of the scale-space of the histogram f...

Neural network based learning of local compatibilities for segment grou**
This paper addresses the automatic inference of a Gibbs distribution dedicated to segment grou** through relaxation labeling. The behavior of this method is studied through the detection of a road-like netwo...

Multi-object deformable templates dedicated to the segmentation of brain deep structures
We propose a new way of embedding shape distributions in a topological deformable template. These distributions rely on global shape descriptors corresponding to the 3D moment invariants. In opposition to usua...

A MRF Based Random Graph Modelling the Human Cortical Topography
This paper presents a project aiming at the automatic detection and recognition of the human cortical sulci in a 3D magnetic resonance image. The two first steps of this project (automatic extraction of an att...
