Impaired tool use despite preserved basic motor functions occurs after stroke in the context of apraxia, a cognitive motor disorder. To elucidate the neuroanatomical underpinnings of different tool use deficits, prospective behavioral assessments of 136 acute left-hemisphere stroke patients were combined with lesion delineation on magnetic resonance imaging (MRI) images for voxel-based lesion-symptom mapping. Deficits affecting both the selection of the appropriate recipient for a given tool…

Distinct Contributions of Dorsal and Ventral Streams to Imitation of Tool-Use and Communicative Gestures

Transitive and intransitive gestures differentially rely on ventro-dorsal and ventral streams due to higher demands on temporo-spatial processing (transitive) or stronger reliance on semantic information (intransitive), respectively.

Apraxia is a debilitating cognitive motor disorder that frequently occurs after left hemisphere stroke and affects tool-associated and imitative skills. However, the severity of the apraxic deficits

Single-case disconnectome lesion-symptom mapping: Identifying two subtypes of limb apraxia

It is demonstrated that relatively focal lesions to specific portions of the Tool Use Network can be associated with distinct limb apraxia subtypes and graph theoretic analysis of each participant’s structural disconnectome demonstrated that disproportionately worse meaningless gesture imitation performance was associated with disconnection among the left inferior parietal lobule, the left superior parietal lobe, and the left middle and superior frontal gyri.

Critical brain regions for tool-related and imitative actions: a componential analysis.

Visual posture information and kinematic capacities are differentially critical to the three types of actions studied here: the kinematics aspect is particularly critical for imitation of meaningless movement, capacity for tool-action posture representations are particularly necessary for pantomimed gestures to the sight of tools, and both capacities inform imitation of tool-related movements.

The neural basis of tool use.

The contribution of the parietal lobe to tool use concerns general principles of tool use rather than knowledge about the prototypical use of common tools and objects, and the comprehension of mechanical interactions of the tool with other tools, recipients or material rather than the selection of grip formation and manual movements.

Neural bases of imitation and pantomime in acute stroke patients: distinct streams for praxis.

Results indicate that imitation mainly relies on the dorso-dorsal stream for visuo-motor conversion and on-line movement control, and pantomime additionally requires ventro- dorsal and ventral streams for access to stored action engrams and retrieval of tool-action relationships.

The Neural Correlates of Planning and Executing Actual Tool Use

It is found that object manipulations with both right and left hand recruit a common network strongly lateralized to the left hemisphere especially during planning but also action execution, providing evidence for left-lateralized occipito-temporo-parieto-frontal network of everyday tool use, which may help to characterize specific deficits in patients suffering from apraxia.
