“…As can be seen, the relationship is much weaker, and not statistically significant. In addition to providing a convenient control, this result is also consistent with aforementioned evidence that poor singing is specific to the pitch dimension (e.g., Dalla Bella et al, 2007), and is consistent with recent evidence suggesting that asynchronous AAF influences a distinct neural network from pitch alterations (Pfordresher et al, 2014). …”

Previous research has demonstrated that altered auditory feedback (AAF) disrupts music performance and causes disruptions in both action planning and the perception of feedback events. It has been proposed that this disruption occurs because of interference within a shared representation for perception and action (Pfordresher, 2006). Studies reported here address this claim from the standpoint of error monitoring. In Experiment 1 participants performed short melodies on a keyboard while hearing no auditory feedback, normal auditory feedback, or alterations to feedback pitch on some subset of events. Participants overestimated error frequency when AAF was present but not for normal feedback. Experiment 2 introduced a concurrent load task to determine whether error monitoring requires executive resources. Although the concurrent task enhanced the effect of AAF, it did not alter participants’ tendency to overestimate errors when AAF was present. A third correlational study addressed whether effects of AAF are reduced for a subset of the population who may lack the kind of perception/action associations that lead to AAF disruption: poor-pitch singers. Effects of manipulations similar to those presented in Experiments 1 and 2 were reduced for these individuals. We propose that these results are consistent with the notion that AAF interference is based on associations between perception and action within a forward internal model of auditory-motor relationships.

“…Maidhof et al, 2009; see Keller, 2012b), could be predicted based on the beta band synchronization between pFMC and brain regions implementing control adjustments (i.e., lateral prefrontal cortex) (Ruiz et al, 2009). These electrophysiological findings are further corroborated by fMRI evidence demonstrating that the alteration of pitch feedback during piano performance modulates the BOLD signal within the anterior cingulate cortex, as well as in motor regions such as the cerebellum and the supplementary motor area (Pfordresher et al, 2014). Taken together, these data indicate further that musical training leads to a tight coupling between sensory and motor cortices, and that this coupling might underpin the generation of sensory predictions—based on internal models— within the musician’s brain.…”

Experience with a sensorimotor task, such as practicing a piano piece, leads to strong coupling of sensory (visual or auditory) and motor cortices. Here we review behavioral and neurophysiological (M/EEG, TMS and fMRI) research exploring this topic using the brain of musicians as a model system. Our review focuses on a recent body of evidence suggesting that this form of coupling might have (at least) two cognitive functions. First, it leads to the generation of equivalent predictions (concerning both when and what event is more likely to occur) during both perception and production of music. Second, it underpins the common coding of perception and action that supports the integration of the motor output of multiple musicians’ in the context of joint musical tasks. Essentially, training-based coupling of perception and action might scaffold the human ability to represent complex (structured) actions and to entrain multiple agents—via reciprocal prediction and adaptation—in the pursuit of shared goals.

“…There is evidence suggesting that both regions cooperate in sequence planning and evaluation (Nachev et al, 2008), though the exact function is not yet completely clear. The pre-SMA has been shown to be concerned with complex sequence planning, task switching, resolving conflicts and sequence learning: for instance, increased activity in this region was observed when musical sequences played on a keyboard were disrupted by delay or false notes (Pfordresher et al, 2014).…”

) for a scientific commentary on this article.Musical memory is considered to be partly independent from other memory systems. In Alzheimer's disease and different types of dementia, musical memory is surprisingly robust, and likewise for brain lesions affecting other kinds of memory. However, the mechanisms and neural substrates of musical memory remain poorly understood. In a group of 32 normal young human subjects (16 male and 16 female, mean age of 28.0 AE 2.2 years), we performed a 7 T functional magnetic resonance imaging study of brain responses to music excerpts that were unknown, recently known (heard an hour before scanning), and long-known. We used multivariate pattern classification to identify brain regions that encode long-term musical memory. The results showed a crucial role for the caudal anterior cingulate and the ventral pre-supplementary motor area in the neural encoding of long-known as compared with recently known and unknown music. In the second part of the study, we analysed data of three essential Alzheimer's disease biomarkers in a region of interest derived from our musical memory findings (caudal anterior cingulate cortex and ventral pre-supplementary motor area) in 20 patients with Alzheimer's disease (10 male and 10 female, mean age of 68.9 AE 9.0 years) and 34 healthy control subjects (14 male and 20 female, mean age of 68.1 AE 7.2 years). Interestingly, the regions identified to encode musical memory corresponded to areas that showed substantially minimal cortical atrophy (as measured with magnetic resonance imaging), and minimal disruption of glucose-metabolism (as measured with 18 F-fluorodeoxyglucose positron emission tomography), as compared to the rest of the brain. However, amyloid-b deposition (as measured with 18 F-flobetapir positron emission tomography) within the currently observed regions of interest was not substantially less than in the rest of the brain, which suggests that the regions of interest were still in a very early stage of the expected course of biomarker development in these regions (amyloid accumulation ! hypometabolism ! cortical atrophy) and therefore relatively well preserved. Given the observed overlap of musical memory regions with areas that are relatively spared in Alzheimer's disease, the current findings may thus explain the surprising preservation of musical memory in this neurodegenerative disease.
