The distinctions between the neural resources supporting speech and music comprehension have long been studied using contexts like aphasia and amusia, and neuroimaging in control subjects. While many models have emerged to describe the different networks uniquely recruited in response to speech and music stimuli, there are still many questions, especially regarding left-hemispheric strokes that disrupt typical speech-processing brain networks, and how musical training might affect the brain networks recruited for speech after a stroke. Thus, our study aims to explore some questions related to the above topics. We collected task-based functional MRI data from 12 subjects who previously experienced a left-hemispheric stroke. Subjects listened to blocks of spoken sentences and novel piano melodies during scanning to examine the differences in brain activations in response to speech and music. We hypothesized that speech stimuli would activate right frontal regions, and music stimuli would activate the right superior temporal regions more than speech (both findings not seen in previous studies of control subjects), as a result of functional changes in the brain, following the left-hemispheric stroke and particularly the loss of functionality in the left temporal lobe. We also hypothesized that the music stimuli would cause a stronger activation in right temporal cortex for participants who have had musical training than those who have not. Our results indicate that speech stimuli compared to rest activated the anterior superior temporal gyrus bilaterally and activated the right inferior frontal lobe. Music stimuli compared to rest did not activate the brain bilaterally, but rather only activated the right middle temporal gyrus. When the group analysis was performed with music experience as a covariate, we found that musical training did not affect activations to music stimuli specifically, but there was greater right hemisphere activation in several regions in response to speech stimuli as a function of more years of musical training. The results of the study agree with our hypotheses regarding the functional changes in the brain, but they conflict with our hypothesis about musical expertise. Overall, the study has generated interesting starting points for further explorations of how musical neural resources may be recruited for speech processing after damage to typical language networks.

With over a century of culturally established associations for different musical sounds, the narrative properties of film scoring powerfully influence how societies and cultures perceive themselves through film. Film scoring in mainstream culture functions as a form of social practice in which consumers dictate the market that producers create for, while the ideas and philosophies portrayed in film shape consumer audiences’ perceptions of what their societies look like. A surge of discourse in the 21st century surrounds issues of representation and inclusivity in mainstream media, including what constitutes appropriation versus appreciation in film scores using non-Western music traditions. Recent postcolonial ethnomusicological theory demonstrates that collaboration and co-authorship are inclusive ways that can both avoid the pitfalls of colonialist power structures and also create autonomy for participating marginalized groups. My research examines four contemporary films of the 21st century--Kung Fu Panda 3, Moana, Black Panther, and The Breadwinner--and the collaborations between film composers and source musicians that establish cultural and racial musical narratives. I analyze various musical techniques these composers learned through the collaboration process with contributing source musicians and the resulting musical space each film’s soundtrack created for the representative demographic. This discourse opens other avenues of exploration into how mainstream media and the “global imagination” informs cultural music identities. I conclude my research with examples of film scores appearing outside cinema in social musicality; these examples demonstrate the impact that inclusivity in film scoring has on many areas of mainstream culture, especially in racial representation discourse.
