Embedded figures in schizophrenia: A main deficit but no specificity

Michael Herzog, Maya Roinishvili, Ophélie Gladys Favrod, Michel Akselrod

Visual deficits are core deficits of schizophrenia. Classically, deficits are determined with demanding psychophysical tasks requiring fine-grained spatial or temporal resolution. Less is known about holistic processing. Here, we employed the Leuven Embedd ...

Robot-induced hallucinations in Parkinson’s disease depend on altered sensorimotor processing in fronto-temporal network

Dimitri Nestor Alice Van De Ville, Olaf Blanke, Fosco Bernasconi, Jevita Potheegadoo, Nathan Quentin Faivre, Giulio Rognini, Masayuki Hara, Michela Bassolino, Michel Akselrod, Eva Blondiaux

Hallucinations in Parkinson’s disease (PD) are disturbing and frequent non-motor symptoms and constitute a major risk factor for psychosis and dementia. We report a robotics-based approach applying conflicting sensorimotor stimulation, enabling the inducti ...

Relation between palm and finger cortical representations in primary somatosensory cortex: A 7T fMRI study

Olaf Blanke, Andrea Serino, Roberto Martuzzi, Michel Akselrod

Many studies focused on the cortical representations of fingers, while the palm is relatively neglected despite its importance for hand function. Here, we investigated palm representation (PR) and its relationship with finger representations (FRs) in prima ...

Contribution of interaction force to the sense of hand ownership and the sense of hand agency

Olaf Blanke, Roberto Martuzzi, Michel Akselrod

When performing willed actions, we have the unified and coherent experience of owning and controlling our body. Body ownership is believed to emerge from the integration of coherent multisensory signals, while agency is believed to emerge from the coherenc ...

Anatomical and functional properties of the foot and leg representation in areas 3b, 1 and 2 of primary somatosensory cortex in humans: A 7T fMRI study

Olaf Blanke, Wietske Van der Zwaag, Andrea Serino, Roger Gassert, Roberto Martuzzi, Michel Akselrod

Primary somatosensory cortex (S1) processes somatosensory information and is composed of multiple subregions. In particular, tactile information from the skin is encoded in three subregions, namely Brodmann areas (BAs) 3b, 1 and 2, with each area represent ...

Changes in Heart Rate Variability Recorded in Natural Situation with T-Shirt Integrated Sensors and Level of Observed Behavioral Excitation: A Pilot Study of Patients with Intellectual Disabilities and Psychiatric Disorders

Michel Akselrod

Background: The present study investigates the possibilities of using heart rate variability (HRV) parameters as physiological markers that precede increase in observed behavioral excitation of intellectually disabled individuals. The ability to recognize ...

Upper limb cortical maps in amputees with targeted muscle and sensory reinnervation

Olaf Blanke, Andrea Serino, Wietske Van der Zwaag, Roy Salomon, Giulio Rognini, Roberto Martuzzi, Elisa Canzoneri, Michel Akselrod, Maria Laura Blefari

Neuroprosthetics research in amputee patients aims at developing new prostheses that move and feel like real limbs. Targeted muscle and sensory reinnervation (TMSR) is such an approach and consists of rerouting motor and sensory nerves from the residual li ...
