CONDUCTION APRAXIA

A left hemisphere damaged patient with ideomotor apraxia is described, whose performance on pantomime to verbal command was superior to pant omime imitation. His reception of these same gestures (gesture naming) was spared. This syndrome has been named conduction apraxia. To accou nt for this selective impaired performance on gesture imitation, a sep aration of the representations for gesture production and reception is proposed and a non-lexical gesture processing route for gesture imita tion is suggested.
