Representation of Sound Objects within Early-Stage Auditory Areas: A Repetition Effect Study Using 7T fMRI

Wietske Van der Zwaag, Melissa Saenz, Stephanie Clarke

Environmental sounds are highly complex stimuli whose recognition depends on the interaction of top-down and bottom-up processes in the brain. Their semantic representations were shown to yield repetition suppression effects, i. e. a decrease in activity d ...

The Brain Network reflecting Bodily Self-Consciousness: a functional connectivity study

Olaf Blanke, Roy Salomon, Roberto Martuzzi, Silvio Ionta

Several brain regions are important for processing self-location and first-person perspective, two important aspects of bodily self-consciousness. However, the interplay between these regions has not been clarified. In addition, while self-location and fir ...

Revisiting a study of callosal apraxia: The right hemisphere can imitate the orientation but not the position of the hand

Aude Billard, Biljana Petreska von Ritter-Zahony

Callosal disconnection can reveal asymmetrical contributions of the two brain hemispheres to praxis. In this paper, we revisit a study of a patient with callosal disconnection (Goldenberg et al., 2001, Neuropsychologia, 39:1432–1443), who perfectly imitate ...

Mental imagery for full and upper human bodies: common right hemisphere activations and distinct extrastriate activations

Olaf Blanke, Christine Mohr, Silvio Ionta

The processing of human bodies is important in social life and for the recognition of another person's actions, moods, and intentions. Recent neuroimaging studies on mental imagery of human body parts suggest that the left hemisphere is dominant in body pr ...

Impaired Imagery for Upper Limbs

Olaf Blanke

The brain processes associated with mental imagery have long been a matter of debate. Neuroimaging and neuropsychological studies have yielded diverging evidence of mental transformation activating the right hemisphere, the left hemisphere, or both. Here, ...

Hand preference and sex shape the architecture of language networks

Jean-Philippe Thiran, Patric Hagmann, Reto Meuli, Leila Cammoun

In right-handed subjects, language processing relies predominantly on left hemisphere networks, more so in men than in women, and in right- versus left-handers. Using DT-MRI tractography, we have shown that right-handed men are massively interconnected bet ...

From diffusion MRI to brain connectomics

Patric Hagmann

The success of diffusion MRI is deeply rooted in the fact that during their micrometric random displacements water molecules explore tissue microstructure. Hence by labeling magnetically spins of displaced water, diffusion MRI provides us with exquisite in ...
