Influence of galvanic vestibular stimulation on egocentric and object-based mental transformations

Olaf Blanke, Christophe Lopez, Bigna Lenggenhager

The vestibular system analyses angular and linear accelerations of the head that are important information for perceiving the location of one's own body in space. Vestibular stimulation and in particular galvanic vestibular stimulation (GVS) that allow a s ...

Virtual lesion of ventral premotor cortex impairs visual perception of biomechanically possible but not impossible actions

Silvio Ionta

Single-pulse transcranial magnetic stimulation (TMS) studies show that action observation facilitates the onlooker's cortico-spinal system supporting the notion of motor mirroring. Repetitive transcranial magnetic stimulation (rTMS) over ventral premotor c ...

Hyper-connectivity and hyper-plasticity in the medial prefrontal cortex in the valproic Acid animal model of autism

Henry Markram, Tania Rinaldi, Catherine Perrodin

The prefrontal cortex has been extensively implicated in autism to explain deficits in executive and other higher-order functions related to cognition, language, sociability and emotion. The possible changes at the level of the neuronal microcircuit are ho ...

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. ...

Mapping the Structural Core of Human Cerebral Cortex

Reto Meuli, Patric Hagmann, Leila Cammoun, Xavier Gigandet, Olaf Sporns

Structurally segregated and functionally specialized regions of the human cerebral cortex are interconnected by a dense network of cortico-cortical axonal pathways. Using diffusion spectrum imaging we noninvasively map these pathways within and across cort ...

Investigating signal integration with canonical correlation analysis of fMRI brain activation data

Kerstin Preuschoff

How the brain integrates signals from specific areas has been a longstanding critical question for neurobiologists. Two recent observations suggest a new approach to fMRI data analysis of this question. First, in many instances, the brain analyzes inputs b ...

Brain-Controlled Robots

José del Rocio Millán Ruiz

The idea of moving robots or prosthetic devices not by manual control, but by mere thinking (i.e., the brain activity of human subjects) has fascinated researchers for the last 30 years, but it is only now that first experiments have shown the possibility ...

Dissociation of sustained attention from central executive functions: local activity and interregional connectivity in the theta range

Friedhelm Christoph Hummel

Human brain oscillatory activity was analysed in the electroencephalographic theta frequency range (4-7 Hz) while subjects executed complex sequential finger movements with varying task difficulty and memory load. Local frontal-midline theta activity was a ...

Induction of tau pathology by intracerebral infusion of amyloid-beta-containing brain extract and by amyloid-beta deposition in APP x tau transgenic mice

Tristan Bolmont

Alzheimer's disease presents morphologically with senile plaques, primarily made of extracellular amyloid-beta (A beta) deposits, and neurofibrillary lesions, which consist of intracellular aggregates of hyper-phosphorylated tau protein. To study the in vi ...

EEG-Based Brain-Computer Interaction: Improved Accuracy by Automatic Single-Trial Error Detection

José del Rocio Millán Ruiz, Pierre Ferrez

Brain-computer interfaces (BCIs), as any other interaction modality based on physiological signals and body channels (e.g., muscular activity, speech and gestures), are prone to errors in the recognition of subject's intent. An elegant approach to improve ...
