Three sequential brain activations encode mental transformations of upright and inverted human bodies: a high resolution evoked potential study

Human bodies provide a particularly rich source of visual information. Whereas most previous studies have focused on the neural mechanisms during the perception and recognition of human bodies, the aim of the present study was to investigate the time cours ...

Spatial heterogeneity of functional Magnetic Resonance Imaging indices of dorsolateral prefrontal cortex activation evoked by a working memory task: A comparison of patients with schizophrenia and healthy controls

Background: This study is based on the hypothesis that functional Magnetic Resonance Imaging (fMRI) indices in the dorsolateral prefrontal cortex (DLPFC) of schizophrenia patients are spatially more heterogeneous than healthy controls for activation evoked ...

When motion takes form

Manuel Mercier

When and where is visual motion processed in the human brain? This question is highly relevant considering the importance of motion for our perception of the dynamical world surrounding us. In the present work we studied motion processing, firstly through ...

A Surface-based approach to Quantify Local Cortical Gyrification

Jean-Philippe Thiran, Meritxell Bach Cuadra, Marie Schaer, François Lazeyras

The high complexity of cortical convolutions in humans remains a mystery for both engineers to measure and compare it, and for biologists to understand it. We developed a method for the quantification of the cortical area allowed by the process of folding. ...

Genes, Brain Development and Psychiatric Phenotypes in Velo-Cardio-Facial Syndrome

Marie Schaer

Velo-cardio-facial syndrome (VCFS) has been in the focus of intensive research over the last 15 years. The syndrome represents a homogeneous model for studying the effect of a decreased dosage of genes on the development of brain structure and function and ...

Abnormal patterns of cortical gyrification in velo-cardio-facial syndrome (deletion 22q11.2): an MRI study

Marie Schaer, François Lazeyras

Velo-cardio-facial syndrome (VCFS), also known as 22q11.2 deletion syndrome, is a common genetic condition associated with increased risk for developing schizophrenia. Given that cortical malformations play an integral role in the pattern of neuroanatomica ...

A New Method For Measuring Cortical Folding In A 3D Space From MR Images

Jean-Philippe Thiran, Meritxell Bach Cuadra

Development of technologies in the field of neuroimaging brought an increase interest in the quantification of cortical folding (gyrification), notably for neurogenetic and psychiatric disorders that may result from an early abnormal cortical development. ...

Neuromagnetic correlates of visual motion coherence

Jane Aspell

In order to characterize cortical responses to coherent motion we use magnetoencephalography (MEG) to measure human brain activity that is modulated by the degree of global coherence in a visual motion stimulus. Five subjects passively viewed two-phase mot ...

Combining backward masking and transcranial magnetic stimulation in human observers

Michael Herzog, Frank Scharnowski

Both backward masking and transcranial magnetic stimulation (TMS) are capable of hindering perception of a visual target. To study the relationship between these two methods we applied TMS over the occipital pole in combination with the visual backward mas ...

Spatiotemporal characterization of rhythmic activity in rat spinal cord slice cultures

Philippe Renaud, Marc Olivier Heuschkel

Rat spinal networks generate a spontaneous rhythmic output directed to motoneurons under conditions of increased excitation or of disinhibition. It is not known whether these differently induced rhythms are produced by a common rhythm generator. To investi ...
