Revisiting a study of callosal apraxia: The right hemisphere can imitate the orientation but not the position of the hand

Aude Billard, Biljana Petreska von Ritter-Zahony

Callosal disconnection can reveal asymmetrical contributions of the two brain hemispheres to praxis. In this paper, we revisit a study of a patient with callosal disconnection (Goldenberg et al., 2001, Neuropsychologia, 39:1432–1443), who perfectly imitate ...

Movement Curvature Planning through Force Field Internal Models

Aude Billard, Biljana Petreska von Ritter-Zahony

Human motion studies have focused primarily on modeling straight point-to-point reaching movements. However, many goal-directed reaching movements, such as movements directed towards oneself, are not straight but rather follow highly curved trajectories. T ...

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 ...

A Neural Model of Demyelination of the Mouse Spinal Cord

Biljana Petreska von Ritter-Zahony

This paper presents a neural network model of demyelination of the mouse motor pathways, coupled to a central pattern generation (CPG) model for quadruped walking. Demyelination is the degradation of the myelin layer covering the axons which can be caused ...

Auditory motion affects visual biological motion processing

Aude Billard, Biljana Petreska von Ritter-Zahony, Olaf Blanke

The processing of biological motion is a critical, everyday task performed with remarkable efficiency by human sensory systems. Interest in this ability has focused to a large extent on biological motion processing in the visual modality (see, for example, ...

Apraxia: a review

Aude Billard, Biljana Petreska von Ritter-Zahony, Olaf Blanke

Praxic functions are frequently altered following brain lesion, giving rise to apraxia - a complex pattern of impairments that is difficult to assess or interpret. In this chapter, we review the current taxonomies of apraxia and related cognitive and neuro ...

A Neurocomputational Model of an Imitation Deficit following Brain Lesion

Aude Billard, Biljana Petreska von Ritter-Zahony

This paper investigates the neural mechanisms of visuo-motor imitation in humans through convergent evidence from neuroscience. In particular, we consider a deficit in imitation following callosal brain lesion, based on the rational that looking at how imi ...
