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 ...
Hoboken2024The neural correlates of topographical disorientation-a lesion analysis study
Olaf Blanke, Lukas Heydrich, Eva Blondiaux
Topographical disorientation refers to the selective inability to orient oneself in familiar surroundings. However, to date its neural correlates remain poorly understood. Here we use quantitative lesion analysis and a lesion network mapping approach in or ...
Hoboken2024An immersive virtual reality system for ecological assessment of peripersonal and extrapersonal unilateral spatial neglect
Olaf Blanke, Andrea Serino, Roberta Ronchi
BackgroundUnilateral spatial neglect (USN) is a debilitating neuropsychological syndrome that often follows brain injury, in particular a stroke affecting the right hemisphere. In current clinical practice, the assessment of neglect is based on old-fashion ...
BMC2023Aesthetic experience enhances first-person spatial representation
Mariana Babo Rebelo, Marie Chatel
Episodic autobiographical memories are characterized by a spatial context and an affective component. But how do affective and spatial aspects interact? Does affect modulate the way we encode the spatial context of events? We investigated how one element o ...
NATL ACAD SCIENCES2022Common and distinct brain networks of autoscopic phenomena
Olaf Blanke, Lukas Heydrich, Eva Blondiaux
Objective Autoscopic phenomena (AP) are illusory own body reduplications characterized by the visual perception of a second own body in extrapersonal space, and include three main forms: autoscopic hallucination (AH), heautoscopy (HAS) and out-of-body-expe ...
2021Resting-state EEG topographies: Reliable and sensitive signatures of unilateral spatial neglect
Dimitri Nestor Alice Van De Ville, Elvira Pirondini
Theoretical advances in the neurosciences are leading to the development of an increasing number of proposed interventions for the enhancement of functional recovery after brain damage. Integration of these novel approaches in clinical practice depends on ...
2020Disownership of body parts as revealed by a visual scale evaluation. An observational study
Olaf Blanke, Roberta Ronchi, Michela Bassolino, Giuseppe Vallar, Dragana Viceic
The disownership of body parts, that most frequently occurs on the left side of the body, contralateral to right-hemispheric lesions, is an infrequent disorder, as usually assessed by interviews asking for dichotomic "yes/no" responses. This observational ...
2020Reply to: “1.5 Dissociation” of somatoparaphrenia for the upper limb and neglect for the lower limb following a thalamic stroke presenting as flaccid hemiparesis: rehabilitation applications and neuroscience implications
This interesting case study reports on a patient who subsequent to a right thalamic hematoma developed a left hemiparesis, left extrapersonal and personal hemineglect and somatoparaphrenia, but only for the arm not the leg. It is not specifically mentioned ...
2019Using real-time fMRI neurofeedback to restore right occipital cortex activity in patients with left visuo-spatial neglect: proof-of-principle and preliminary results
Dimitri Nestor Alice Van De Ville, Frank Scharnowski
Hemineglect is common after right parietal stroke, characterised by impaired awareness for stimuli in left visual space, with suppressed neural activity in the right visual cortex due to losses in top-down attention signals. Here we sought to assess whethe ...
ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD2019A Multifaceted Approach to Covert Attention Brain-Computer Interfaces
Over the last years, brain-computer interfaces (BCIs) have shown their value for assistive
technology and neurorehabilitation. Recently, a BCI-approach for the rehabilitation of hemispatial
neglect has been proposed on the basis of covert visuospatial atte ...
