“…Preferred music enhanced the identification of contralesional targets in a perceptual report test; it facilitated the simple detection of targets; it led to more accurate midline bisection judgments (overcoming the usual bias to the ipsilesional side); it increased the cancellation of contralesional targets; and it even improved the reading of pronounceable nonwords on the contralesional side of space Recent research has shown that music can modulate different aspects of performance in stroke populations generally, accelerating overall cognitive recovery (i.e., verbal memory and attentional focusing) and improving mood in the early acute stages following a stroke (19). In line with this, previous research has shown that alerting by means of auditory stimulation (9,10) and by introducing a noradrenergic agonist (28) can improve awareness of contralesional information in neglect patients. Also, recent research in healthy individuals has shown intense arousal responses (indexed by the GSR) to emotionally powerful music selected by the participants (22).…”

“…The results demonstrate that neglect and extinction can be influenced by grouping between contralesional and ipsilesional stimuli (7,8), alerting by means of auditory stimulation (9,10), spatial cuing to the contralateral side of space (4,5), matches between the current contents of working memory and the visual array (11), and emotional factors associated with the stimulus (i.e., happy or angry faces in the contralesional visual field are extinguished less than neutral faces) (12). However, the potential role of the individual's own emotional state in modulating awareness has been largely overlooked.…”

“…We note that cognitive effects of arousal have been related to a facilitation of decision-level processes when responding to relevant behavioral targets (24), and also related to improvements in attentional orienting (25,26). Importantly, there is evidence that alerting patients with visual neglect through auditory stimulation can improve their awareness of the contralesional side of space (9,10). In addition to this, the valence of the music stimulation may lead to mood changes.…”

During the past 20 years there has been much research into the factors that modulate awareness of contralesional information in neurological patients with visual neglect or extinction. However, the potential role of the individual's emotional state in modulating awareness has been largely overlooked. In the current study, we induced a pleasant and positive affective response in patients with chronic visual neglect by allowing them to listen to their pleasant preferred music. We report that the patients showed enhanced visual awareness when tasks were performed under preferred music conditions relative to when tasks were performed either with unpreferred music or in silence. These results were also replicated when positive affect was induced before neglect was tested. Functional MRI data showed enhanced activity in the orbitofrontal cortex and the cingulate gyrus associated with emotional responses when tasks were performed with preferred music relative to unpreferred music. Improved awareness of contralesional (left) targets with preferred music was also associated with a strong functional coupling between emotional areas and attentional brain regions in spared areas of the parietal cortex and early visual areas of the right hemisphere. These findings suggest that positive affect, generated by preferred music, can decrease visual neglect by increasing attentional resources. We discuss the possible roles of arousal and mood in generating these effects.attention ͉ brain damage ͉ neuropsychology ͉ positive affect ͉ vision

“…Hommel et al (1990), and Soto et al (2009) found in their studies that music listening can improve left-side visual awareness in stroke patients suffering from left-side neglect. In Denmark, music therapists used the method of Guided Imagery and Music (GIM) in rehabilitation to help such patients while listening to, for example, Mahler's Fourth Symphony.…”

“…Music therapy within neurorehabilitation settings is still a relatively new phenomenon (Baker & Tamplin, 2010). Yet although a number of former studies have striven to show the importance of using music or music therapy in stroke rehabilitation (Särkämö, 2011;Thaut, 1997;Hommel et al, 1990;Soto et al 2009;Bradt, Magee, Dileo, Wheeler & McGilloway, 2010) not so many have been made from the perspective of the music therapists themselves. Considering these are the people most involved with this part of the stroke rehabilitation process, it seems only fair to ask them more closely as to how it actually occurs.…”

The aim of this qualitative study is to gain more insight into the skills and knowledge that music therapists feel they need, in order to work successfully with people who have had an acute stroke. For this purpose, six music therapists were interviewed about their own particular specialist education. Another interview topic for them was to recount their subjective experiences of poststroke rehabilitation work in hospitals and health care units during the course of two projects that they participated in. The first was a project that specifically used music listening during acute stroke rehabilitation; and the second was a project, which used more active music therapy techniques, like drumming during acute stroke rehabilitation.In the first project, patients who were bedridden in hospitals or health care units could listen to familiar songs that stimulated them in both a physical and cognitive way, and helped them to relax and regulate their moods better. In the second project different therapeutic approaches were observed and reflected upon during the piloting phase of the project and then an ideal combination of the activities was defined for the main phase. The resulting clinical music therapy model was thus created to specifically meet the special needs of stroke patients.Three crucial factors gleaned from the interviews that were seen to affect clinical thinking were: a) knowledge concerning the neurological basis of strokes; b) good patient interaction; and c) accurate observation of the physiological and psychological aspects of music therapy. In this way, these results provide a better understanding of the tacit knowledge possessed by music therapists who work within stroke rehabilitation.
