Embedded figures in schizophrenia: A main deficit but no specificity

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

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, Michel Akselrod, Masayuki Hara, Giulio Rognini, Eva Blondiaux, Stéphanie Konik, Michela Bassolino, Nathan Quentin Faivre, Fosco Bernasconi, Matteo Franza, Jevita Potheegadoo, Giedre Stripeikyte

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

Roberto Martuzzi, Olaf Blanke, Michel Akselrod, Andrea Serino

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

Roberto Martuzzi, Olaf Blanke, 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

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

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

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

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 ...

Multiscale body maps in the human brain

Michel Akselrod

A large number of brain regions are dedicated to processing information from the body in order to enable interactions with the environment. During my thesis, I studied the functional organization of brain networks involved in processing bodily information. ...

Tracing path-guided apparent motion in human primary visual cortex V1

Michael Herzog, Michel Akselrod

Vision is a constructive process. For example, a square, flashed at two distinct locations one after the other, appears to move smoothly between the two locations rather than as two separate flashes (apparent motion). Apparent motion is usually perceived a ...
