An immersive virtual reality tool for assessing left and right unilateral spatial neglect

Olaf Blanke, Andrea Serino, Roberta Ronchi

The reported rate of the occurrence of unilateral spatial neglect (USN) is highly variable likely due to the lack of validity and low sensitivity of classical tools used to assess it. Virtual reality (VR) assessments try to overcome these limitations by pr ...

A brief exposure to rightward prismatic adaptation changes resting-state network characteristics of the ventral attentional system

Patric Hagmann, Stephanie Clarke

A brief session of rightward prismatic adaptation (R-PA) has been shown to alleviate neglect symptoms in patients with right hemispheric damage, very likely by switching hemispheric dominance of the ventral attentional network (VAN) from the right to the l ...

Age-Dependent Asymmetry of Wrist Position Sense Is Not Influenced by Stochastic Tactile Stimulation

Jamie Paik, Olivier Lambercy, Harshal Arun Sonar

Stochastic stimulation has been shown to improve movement, balance, the sense of touch, and may also improve position sense. This stimulation can be non-invasive and may be a simple technology to enhance proprioception. In this study, we investigated wheth ...

Dopaminergic modulation of cortical motor network lateralization

Michael Herzog, Maya Anna Jastrzebowska, Bogdan Draganski, Lester Melie Garcia, Renaud Marquis

Introduction Unilateral movements are primarily processed in contralateral cortical and subcortical areas and additionally in ipsilateral cerebellum, leading to an asymmetric pattern of neural activation. Decrease of lateralization is characteristic of agi ...

Temporal Dissociation of Neocortical and Hippocampal Contributions to Mental Time Travel Using Intracranial Recordings in Humans

Olaf Blanke

In mental time travel (MTT) one is "traveling" back-and-forth in time, remembering, and imagining events. Despite intensive research regarding memory processes in the hippocampus, it was only recently shown that the hippocampus plays an essential role in e ...

Human EEG reveals distinct neural correlates of power and precision grasping types

José del Rocio Millán Ruiz, Ricardo Andres Chavarriaga Lozano, Robert Leeb, Inaki Asier Iturrate Gil, Michael Eric Anthony Pereira, Huaijian Zhang, Tiffany Corbet

Hand grasping is a sophisticated motor task that has received much attention by the neuroscientific community, which demonstrated how grasping activates a network involving parietal, pre-motor and motor cortices using fMRI, ECoG, LFPs and spiking activity. ...

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 ...

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 ...

Crossed somatoparaphrenia: an unusual new case and a review of the literature

Olaf Blanke, Lukas Heydrich

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- ...

Intrahemispheric cortico-cortical connections of the human auditory cortex

Jean-Philippe Thiran, Alessandra Griffa, Patric Hagmann, Reto Meuli, Leila Cammoun, Stephanie Clarke

The human auditory cortex comprises the supratemporal plane and large parts of the temporal and parietal convexities. We have investigated the relevant intrahemispheric cortico-cortical connections using in vivo DSI tractography combined with landmark-base ...
