Effector-independent brain network for auditory-motor integration: fMRI evidence from singing and cello playing.

摘要: Abstract Many everyday tasks share high-level sensory goals but differ in the movements used to accomplish them. One example of this is musical pitch regulation, where same notes can be produced using vocal system or a instrument controlled by hands. Cello playing has previously been shown rely on brain structures within singing network for performance single notes, except areas related primary motor control, suggesting that networks auditory feedback processing and sensorimotor integration may shared (Segado et al. 2018). However, research singers cellists alike continue singing/playing tune even absence (Chen 2013, Kleber 2013), so different paradigms are required test monitoring control mechanisms. In singing, perturbation have show engage regions including anterior cingulate cortex (ACC), insula (aINS), intraparietal sulcus (IPS) when compensating altered feedback, posterior superior temporal gyrus (pSTG) supramarginal (SMG) ignoring it (Zarate 2005, 2008). To determine whether cello directly overlap these sensory-motor areas, present study expert were asked compensate ignore introduced perturbations during fMRI scanning. We found able sing/play target tones, equally well. Brain activity overlapped IPS SMG compensating, pSTG dPMC ignoring; differences between across all three conditions most prominent M1, centered relevant effectors (hand, larynx). These findings support hypothesis regulation relies suggests arise primarily at level forward control.
