Abstract

Insights into the neural mechanisms underlying hand praxis: implications for the neurocognitive rehabilitation of apraxia.

Highlights

The understanding of the neural basis of limb apraxia has benefited greatly from cognitive research on gesture processing and recognition, but the influence of this research on the treatment of apraxia is limited (Cantagallo et al, 2012)
The effects of visual half-field priming on the categorization of familiar intransitive gestures, tool use pantomimes, and meaningless hand movements by Helon, H., and Kroliczak, G. (2014)
Helon and Kroliczak’s (2014) finding that categorization of transitive and intransitive gestures were affected by both pictorial and linguistic priming in the right-visual field (RVF) suggests that communicative and tool-use actions share a left-lateralized mechanism intersecting language functions

Summary

Introduction

The understanding of the neural basis of limb apraxia (deficits in performing previously learned skilled movements) has benefited greatly from cognitive research on gesture processing and recognition, but the influence of this research on the treatment of apraxia is limited (Cantagallo et al, 2012).
