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 ...
Oxford Univ Press2014Multisensory Origin of the Subjective First-Person Perspective: Visual, Tactile, and Vestibular Mechanisms
Olaf Blanke, Roberto Martuzzi, Christophe Lopez, Christian Pfeiffer, Valentin Marc Schmutz, Julio Duenas
In three experiments we investigated the effects of visuo-tactile and visuo-vestibular conflict about the direction of gravity on three aspects of bodily self-consciousness: self-identification, self-location, and the experienced direction of the first-per ...
Public Library of Science2013Digit somatotopy in the human cerebellum: A 7T fMRI study
Rolf Gruetter, Olaf Blanke, Wietske Van der Zwaag, José Pedro Rebelo Ferreira Marques, Roberto Martuzzi, Remy Kusters
The representation of the human body in the human cerebellum is still relatively unknown, compared to the well-studied homunculus in the primary somatosensory cortex. The investigation of the body representation in the cerebellum and its somatotopic organi ...
Academic Press Inc Elsevier Science2013Neuroscience robotics to investigate multisensory integration and bodily awareness
Olaf Blanke, Dominique Chapuis, Roger Gassert, Roberto Martuzzi, Silvio Ionta, Christian Pfeiffer, Julio Duenas
Humans experience the self as localized within their body. This aspect of bodily self-consciousness can be experimentally manipulated by exposing individuals to conflicting multisensory input, or can be abnormal following focal brain injury. Recent technol ...
2012A whole-brain voxel based measure of intrinsic connectivity contrast reveals local changes in tissue connectivity with anesthetic without a priori assumptions on thresholds or regions of interest
The analysis of spontaneous fluctuations of functional magnetic resonance imaging (fMRI) signals has recently gained attention as a powerful tool for investigating brain circuits in a non-invasive manner. Correlation-based connectivity analysis investigate ...
2011Functional MRI connectivity as a predictor of the surgical outcome of epilepsy
Purpose: In planning epilepsy surgery, it is important to be able to assess the likelihood of success of surgery for each patient so that the possible risk and benefit can be properly considered. In this study, functional connectivity was investigated as ...
2011Working memory load improves early stages of independent visual processing
Increasing evidence suggests that working memory and perceptual processes are dynamically interrelated due to modulating activity in overlapping brain networks. However, the direct influence of working memory on the spatio-temporal brain dynamics of behavi ...
2010Perceptual and semantic contributions to repetition priming of environmental sounds
Roberto Martuzzi, Stephanie Clarke
Repetition of environmental sounds, like their visual counterparts, can facilitate behavior and modulate neural responses, exemplifying plasticity in how auditory objects are represented or accessed. It remains controversial whether such repetition priming ...
2009Methods for Determining Frequency- and Region-Dependent Relationships Between Estimated LFPs and BOLD Responses in Humans
Jean-Philippe Thiran, Roberto Martuzzi
The relationship between electrophysiological and functional magnetic resonance imaging (fMRI) signals remains poorly understood. To date, studies have required invasive methods and have been limited to single functional regions and thus cannot account for ...
2009Functional connectivity and alterations in baseline brain state in humans
This work examines the influence of changes in baseline activity on the intrinsic functional connectivity fMRI (fc-fMRI) in humans. Baseline brain activity was altered by inducing anesthesia (sevoflurane end-tidal concentration 1%) in human volunteers and ...
