Emergent leaders through looking and speaking: from audio-visual data to multimodal recognition

Daniel Gatica-Perez, Oya Aran, Dinesh Babu Jayagopi, Dairazalia Sanchez Cortes

In this paper we present a multimodal analysis of emergent leadership in small groups using audio-visual features and discuss our experience in designing and collecting a data corpus for this purpose. The ELEA Audio-Visual Synchronized corpus (ELEA AVS) wa ...

Nlgn4 knockout induces network hypo-excitability in juvenile mouse somatosensory cortex in vitro

Henry Markram, Vincent Delattre, Julie Meystre, Deborah La Mendola, Kamila Markram

Neuroligins (Nlgns) are postsynaptic cell adhesion molecules that form transynaptic complexes with presynaptic neurexins and regulate synapse maturation and plasticity. We studied the impact of the loss of Nlgn4 on the excitatory and inhibitory circuits in ...

The Ciliogenic Transcription Factor RFX3 Regulates Early Midline Distribution of Guidepost Neurons Required for Corpus Callosum Development

The corpus callosum (CC) is the major commissure that bridges the cerebral hemispheres. Agenesis of the CC is associated with human ciliopathies, but the origin of this default is unclear. Regulatory Factor X3 (RFX3) is a transcription factor involved in t ...

Mesenchymal stem cells restore cortical rewiring after neonatal ischemia in mice

Yohan Van de Looij

Objective: A study was undertaken to investigate the effect of neonatal hypoxic-ischemic (HI) brain damage and mesenchymal stem cell (MSC) treatment on the structure and contralesional connectivity of motor function-related cerebral areas. Methods: Brain r ...

VAX1 Mutation Associated with Microphthalmia, Corpus Callosum Agenesis, and Orofacial Clefting: The First Description of a VAX1 Phenotype in Humans

Vax1 and Vax2 have been implicated in eye development and the closure of the choroid fissure in mice and zebrafish. We sequenced the coding exons of VAX1 and VAX2 in 70 patients with anophthalmia/microphthalmia (A/M). In VAX1, we observed homozygosity for ...

High-field diffusion tensor imaging characterization of cerebral white matter injury in lipopolysaccharide-exposed fetal sheep

Yohan Van de Looij, François Lazeyras

BACKGROUND: In gyrencephalic species such as sheep, precise anatomical and microstructural characterization of the consequences of fetal inflammation remains scarce. The goal of this study was to characterize changes in white matter (WM) structure using ad ...

Automatic Speaker Role Labeling in AMI Meetings: Recognition of Formal and Social Roles

Fabio Valente, Ashtosh Sapru

This work aims at investigating the automatic recognition of speaker role in meeting conversations from the AMI corpus. Two types of roles are considered: formal roles, fixed over the meeting duration and recognized at recording level, and social roles rel ...

An Audio Visual Corpus for Emergent Leader Analysis

Daniel Gatica-Perez, Oya Aran, Dairazalia Sanchez Cortes

In this paper we discuss our experience designing and collecting a data corpus called ELEA (Emergent LEader Analysis), and describe the use of a light portable scenario to record small group meetings. The corpus was gathered with the aim of analyzing emerg ...

Interhemispheric motor networks are abnormal in patients with Gilles de la Tourette syndrome

Friedhelm Christoph Hummel

Brain imaging has shown altered corpus callosum (CC) morphology in patients with Gilles de la Tourette syndrome (GTS). Yet it is unclear whether these morphological changes are associated with altered interhemispheric interactions. Here, we combined transc ...

Biophysical Basis of the Diffusion-Weighted Magnetic Resonance Signal in the Rat Brain

Nicolas Kunz

Nuclear magnetic resonance (NMR) can be used in-vivo in a vast array of applications, such as anatomical imaging (magnetic resonance imaging, MRI), localized chemical composition characterization (magnetic resonance spectroscopy, MRS), cellular structure a ...
