The paper investigates how lesions in temporal and parietal regions affect neural responses in the left inferior frontal gyrus during word fluency tasks.

The paper shows that lesions in specific brain areas affect different motor speech coordination networks, supporting distinct sensory-to-motor transformations for laryngeal and orofacial control.

The paper shows that parietal action systems modulate ventral stream processing of manipulable objects via structural connectivity, using lesion and diffusion MRI data.

This study investigates response selection mechanisms in tool and non-tool actions after left-hemisphere stroke, finding distinct neural substrates for grasp-use interference and response interference in different tasks.

The paper identifies two subtypes of limb apraxia based on distinct neuroanatomic lesion profiles using structural MRI and graph analysis in stroke patients.

The paper identifies structural disconnection patterns in the brain that predict severity of limb apraxia after left hemisphere stroke.

This study investigates tool action errors in left hemisphere stroke patients, finding reduced competition between tool actions in both grasp-on-use conflict and tool neighbor scenarios.
