Electrical spinal cord stimulation must preserve proprioception to enable locomotion in humans with spinal cord injury

Silvestro Micera, Grégoire Courtine, Jocelyne Bloch, Marco Capogrosso, Fabien Bertrand Paul Wagner, Jean-Baptiste Mignardot, Emanuele Formento, Karen Minassian, Andreas Rowald, Camille Georgette Marie Le Goff-Mignardot

Epidural electrical stimulation (EES) of the spinal cord restores locomotion in animal models of spinal cord injury but is less effective in humans. Here we hypothesized that this interspecies discrepancy is due to interference between EES and propriocepti ...

Optimal visuo-vestibular integration for self-motion perception in patients with unilateral vestibular loss

Olaf Blanke, Mariia Kaliuzhna, Steven Gale

Unilateral vestibular loss (UVL) is accompanied by deficits in processing of visual and vestibular self-motion cues. The present study examined whether multisensory integration of these two types of information is, nevertheless, intact in such patients. Pa ...

Human-environment interactions are mediated through the body and occur within the peripersonal space (PPS), the space immediately adjacent to and surrounding the body. The PPS is taken to be a critical interface between the body and the environment, and in ...

Neural adaptation accounts for the dynamic resizing of peripersonal space: evidence from a psychophysical-computational approach

Olaf Blanke, Andrea Serino, Jean-Paul Noel

Interactions between the body and the environment occur within the peripersonal space (PPS), the space immediately surrounding the body. The PPS is encoded by multisensory (audio-tactile, visual-tactile) neurons that possess receptive fields (RFs) anchored ...

Behavioral and cortical effects during attention driven brain-computer interface operations in spatial neglect: A feasibility case study

José del Rocio Millán Ruiz, Robert Leeb, Luca Tonin, Huaijian Zhang

During the last years, several studies have suggested that Brain-Computer Interface (BCI) can play a critical role in the field of motor rehabilitation. In this case report, we aim to investigate the feasibility of a covert visuospatial attention (CVSA) dr ...

Illusory hand ownership in a patient with personal neglect for the upper limb, but no somatoparaphenia

Olaf Blanke, Andrea Serino, Roberta Ronchi, Lukas Heydrich

The symptoms of patients with left personal neglect are characterized by inattention towards contralesional (left) body parts while at the same time explicitly ascertaining ownership for the neglected hemibody. It is currently unknown if personal neglect i ...

Delta Power Is Higher and More Symmetrical in Ischemic Stroke Patients with Cortical Involvement

Silvestro Micera, Fiorenzo Artoni

A brain injury resulting from unilateral stroke critically alters brain functionality and the complex balance within the cortical activity. Such modifications may critically depend on lesion location and cortical involvement. Indeed, recent findings pointe ...

Left neglect dyslexia: Perseveration and reading error types

Roberta Ronchi, Giuseppe Vallar

Right-brain-damaged patients may show a reading disorder termed neglect dyslexia. Patients with left neglect dyslexia omit letters on the left-hand-side (the beginning, when reading left-to-right) part of the letter string, substitute them with other lette ...

Visual gravity contributes to subjective first-person perspective

Olaf Blanke, Bruno Herbelin, Andrea Serino, Christian Pfeiffer, Petr Grivaz

A fundamental component of conscious experience involves a first-person perspective (1PP), characterized by the experience of being a subject and of being directed at the world. Extending earlier work on multisensory perceptual mechanisms of 1PP, we here a ...

Oxford Univ Press2016

Somatoparaphrenia is a delusional misidentification and confabulation of body parts, usually arm or hand, opposite to a cerebral lesion, generally of the "minor" right hemisphere. There is some controversy concerning lesion site ( fronto-parietal; parieto- ...
