These deficits seem to occur much more frequently after right hemisphere damage than after left-sided lesions. This suggests that key attentional functions of the right hemisphere are important not only for “cognitive” abilities such as spatial orienting but also for more basic capacities such as visual detection or oculomotor control. Other apparently “low-level” deficits are extinction and deviations of gaze position. Extinction refers to the patient’s inability to report the contralesional stimulus of two stimuli presented simultaneously in the right and left hemispaces, whereas the same stimulus is correctly reported when presented alone in either hemispace. Right hemisphere damage may also induce tonic or phasic gaze deviations towards the right, which have a close relationship with signs of left spatial neglect (Chaps. 4, 5, 6, and 7).

The healthy right hemisphere may play a role in aphasia compensation. Music-based therapy, known to enhance cognitive functions after stroke, offers a potential intervention due to its impact on brain connectivity, engaging both hemispheres. In this proof-of-concept study, we aimed to assess the feasibility and effectiveness of music-assisted therapy for language disorders following left hemisphere strokes. We also sought preliminary insights into the impact of music on post-stroke brain connectivity. We enrolled four right-handed patients (one female and three males, mean age 57.75 years, SD 7.63) who experienced their first left-hemisphere stroke inducing chronic aphasia symptoms three months post-stroke. Patients were randomly assigned to receive either two weeks of music therapy, involving daily 2-hour sessions of listening to instrumental music by Haydn, Mozart, and Beethoven, in addition to standard rehabilitat...
