Impaired Imagery for Upper Limbs

Olaf Blanke

The brain processes associated with mental imagery have long been a matter of debate. Neuroimaging and neuropsychological studies have yielded diverging evidence of mental transformation activating the right hemisphere, the left hemisphere, or both. Here, ...

Three sequential brain activations encode mental transformations of upright and inverted human bodies: a high resolution evoked potential study

Olaf Blanke

Human bodies provide a particularly rich source of visual information. Whereas most previous studies have focused on the neural mechanisms during the perception and recognition of human bodies, the aim of the present study was to investigate the time cours ...

Modeling the neural correlates of imitation from a neuropsychological perspective

Biljana Petreska von Ritter-Zahony

Imitation is a fundamental mechanism by which humans learn and understand the actions of others. This thesis addresses the low-level neural mechanisms underlying the imitation of meaningless gestures, using tools from computational neuroscience. We investi ...

What apraxia tells us about the brain hemispheres’ contributions to human imitation

Aude Billard, Biljana Petreska von Ritter-Zahony

Praxic functions are frequently altered following brain lesion, giving rise to apraxia - a complex pattern of impairments that has proven difficult to assess or interpret. Here we revisit a study on imitation of meaningless gestures in a patient with disco ...

Virtual reality simulator for the training of lumbar punctures

Friedhelm Christoph Hummel

Lumbar puncture (LP) is performed by inserting a needle into the spinal canal to extract cerebrospinal fluid for diagnostic purposes. A virtual reality (VR) lumbar puncture simulator based on real patient data has been developed and evaluated. ...

Motor intention in the posterior parietal cortex

Jugoslava Acimovic

The complexity of processes occurring in the brain is an intriguing issue not just for scientists and medical doctors, but the humanity in general. The cortex ability to perceive and analyze an enormous amount of information in an instance of time, the par ...

EPFL2008

A review of published brain-damaged patients showing delusional beliefs concerning the contralesional side of the body (somatoparaphrenia) is presented. Somatoparaphrenia has been reported, with a few exceptions, in right-brain-damaged patients, with motor ...

Investigating signal integration with canonical correlation analysis of fMRI brain activation data

Kerstin Preuschoff

How the brain integrates signals from specific areas has been a longstanding critical question for neurobiologists. Two recent observations suggest a new approach to fMRI data analysis of this question. First, in many instances, the brain analyzes inputs b ...

2008

The most general and striking evidence related with brain injury is that of the restoration of function. Recovery of motor and somatosensory functions has shown to commonly occur after stroke, but not all individuals show improvement. Clinical studies have ...

Anosognosia for motor and sensory deficits after unilateral brain damage: a review

Roberta Ronchi, Giuseppe Vallar

PURPOSE: The syndrome of unawareness (anosognosia) for sensory and motor neurological deficits (hemiplegia, hemianaesthesia, and hemianopia), contralateral to the side of a hemispheric lesion, is reviewed. CONTENT: Main topics include: basic historical fac ...
