How does human motor cortex regulate vocal pitch in singers?

Abstract: Vocal pitch is used as an important communicative device by humans, as found in the melodic dimension of both speech and song. Vocal pitch is determined by the degree of tension in the vocal folds of the larynx, which itself is influenced by complex and nonlinear interactions among the laryngeal muscles. The relationship between these muscles and vocal pitch has been described by a mathematical model in the form of a set of ‘control rules’. We searched for the biological implementation of these control rules i… Show more

“…Several previous studies have explored the neural correlates of vocal expertise, revealing effects on regional activation and structure, as well as connectivity [33][34][35][50][51][52]. In this study, we found a significant difference between singers and nonsinger controls in the behavioural imitation of VTL, and the neural representation of this vocal parameter.…”

“…The main contrast for vocalization showed some residual activity of the tongue representation. Using the neutral vowel schwa or glottal stops instead ( Gick 2002 ; Loucks et al 2007 ; Brown et al 2008 ; Grabski et al 2012 ; Belyk et al 2018 ), however, might have caused pharynx activity that would have been more difficult to dissociate.…”

“…Our results suggest that controversial findings within the neuroimaging literature can largely be explained by differences in experimental design. Several studies focused on the dorsal region as location of the “laryngeal motor cortex” or “larynx phonation area” ( Sörös et al 2006 ; Brown et al 2008 ; Kleber et al 2013 ; Belyk and Brown 2014 ; Belyk et al 2018 ). Brown et al (2008 ) suggested the presence of a “dorsolateral” larynx representation on the crown of the precentral gyrus ( x = 50, y = –2, z = 37) and a “ventromedial” larynx representation in the central sulcus ( x = 44, y = –8, z = 34).…”

“…Distinct functional contributions of the dLMC and vLMC remain elusive [75,76]. However, electrical stimulation of these regions in the human brain elicit vowel sounds and grunting, respectively [8,16,62].…”
