“…Finally, activations in the cerebellum were associated with interoceptive awareness (Critchley et al, 2004), in the representation of interoceptive signals (Santangelo et al, 2018). A review of the literature even presented the cerebellum as “[…] an embodying machine that provides internal models to integrate bodily information and emotional responses” (Petrosini et al, 2022), and this literature is also in line with the observed brain correlates of vibrations during production in our study. Other brain correlates of vocal tract vibrations specific to normal voice production were also observed in the STG, STS and the inferior temporal sulcus.…”

Despite a large body of literature on the psychological and brain mechanisms of vocal emotion perception, less is known on expression and production mechanisms, especially the vibrations originating in the vocal cords and their role in emotional voice production. In the present study, we aimed to fill this gap. Participants had to produce angry, happy and neutral emotional vocalizations in different production conditions ("normal", "whisper", "articulate"). An accelerometer recorded the vibrations on the throat, close to the vocal folds. Results showed effects of the Emotion factor with activations in the bilateral temporal voice areas, the inferior frontal gyri as well as motor and supplementary motor areas. The Production factor and its interaction with Emotion revealed significant effects in motor, somatosensory cortices, insula and inferior frontal cortex. Exploratory analysis of the brain correlates of emotional vocal tract vibrations specific to "normal" voice production showed significant correlations with brain regions involved in interoceptive processing (insula, inferior frontal cortex, cerebellum). Our results highlight the crucial role of vibro-tactile body resonances in vocal emotion production that might play an important role for the interoceptive phenomena involved in the representation of our own emotions such as in emergent feelings related to emotional vocal production.

“…Multiple theories (Patel and Iversen, 2014;Rauschecker, 2011;Schubotz, 2007) advance that the motor system plays a role even in passive music listening and that it has a predictive contribution in perception (James et al, 2014). Not by chance, research on sensorimotor adaptation has emphasized the role of the cerebellum and its connections in predicting sensory consequences of movement and adapting to errors in these predictions (Petrosini et al, 2022). This involvement in predictive processes might be active in music listening regardless of active motor control is needed, the complexity of auditory stimuli requiring however a high level elaboration.…”

Music represents a salient stimulus for the brain with two key features: pitch and rhythm. Few data are available on cognitive analysis of music listening in musically naïve healthy participants. Beyond auditory cortices, neuroimaging data showed the involvement of prefrontal cortex in pitch and of cerebellum in rhythm. The present study is aimed at investigating the role of prefrontal and cerebellar cortices in both pitch and rhythm processing. The performance of fteen participants without musical expertise was investigated in a listening comparative task. The task required to decide whether two eightelement melodic sequences were equal or different according to pitch or rhythm characteristics. Before the task, we applied a protocol of continuous theta burst transcranial magnetic stimulation interfering with the activity of the left cerebellar hemisphere (lCb), right inferior frontal gyrus (rIFG), or vertex (Czcontrol site), in a within cross-over design. Our results showed that participants were more accurate in pitch than rhythm tasks. Importantly, following rIFG or lCb relative to Cz stimulations, the reaction times were slower and with no difference in both tasks. Notably, no lateralized motor stimulation effect was observed. The present ndings point to the role of the fronto-cerebellar network in music processing with a single mechanism for both pitch and rhythm patterns.

“…Neuroimaging studies suggest that compensatory cerebellar reorganization might be present in neurodegenerative diseases, such as Alzheimer's disease (AD). Although several studies have documented cerebellar involvement in cognitive and emotional processes (Toniolo et al, 2018(Toniolo et al, , 2020Olivito et al, 2020;Petrosini et al, 2022), few studies have directly investigated the role of the cerebellum in the framework of brain/cognitive/neural reserve in clinical populations. Serra et al (2017a) found a significantly decreased brain functional connectivity in a large network involving frontotemporo-cerebellar nodes by comparing a group of patients with amnestic-mild cognitive impairment (a-MCI) and high educational level (a proxy measure of cognitive reserve) against a-MCI patients with low CR.…”

“…This situation is on the whole very surprising since the plastic properties of the cerebellum are currently well-known (Luciani, 1893;Carulli et al, 2004;Cesa and Strata, 2005;Bosman and Konnerth, 2009;Cheron et al, 2016;Mitoma et al, 2021). Cerebellar involvement in cognitive and emotional functions in addition to motor functions has been increasingly ascertained (Schmahmann, 1997;Laricchiuta et al, 2015;Jang and Kim, 2019;De Zeeuw et al, 2021;Picerni et al, 2021Picerni et al, , 2022Petrosini et al, 2022;van Dun et al, 2022). Schmahmann (2019) reports that the cerebellum maintains behavior (in terms of cognition and emotions) around a homeostatic baseline by unconsciously using implicit learning and by adapting actions to context.…”

The ability of the brain to change structure and function in response to experience accounts for its ability to successfully adapt to the environment in both learning processes and unique phases, such as during development and repair. On this basis, the occurrence of the brain, cognitive, and neural reserves has been advanced to explain the discrepancies between the extent of neurological damage and the severity of clinical manifestations described in patients with different life span experiences. Research on this topic highlighted the neuroprotective role of complex stimulations, allowing the brain to better cope with the damage. This framework was initially developed by observing patients with Alzheimer's disease, and it has since been progressively expanded to multifarious pathological states. The cerebellum is known to be particularly responsive to experience through extensive plastic rearrangements. The neuroprotective value exerted by reserve mechanisms appears to be suitable for basic neuronal plasticity in the cerebellum. Thus, it is of primary interest to deepen our understanding of how life experiences modify individuals' cerebellar morphology and functionality. The present study is aimed at analyzing the evidence provided on this topic by animal and human studies. For animals, we considered the studies in which subjects were submitted to enhanced stimulations before the damage occurred. For humans, we considered studies in which previous lifelong high-level experiences were associated with superior cerebellar abilities to cope with injury. Detailed indications of the processes underlying cerebellar reserves may be important in proposing effective interventions for patients suffering from pathologies that directly or indirectly damage cerebellar functionality.
