Cerebral Substrates for Controlling Rhythmic Movements

Naho Konoike, Katsuki Nakamura
2020 Brain Sciences  
In this review, we examine the literature on neuropsychological studies of patients with focal brain lesions, and functional brain imaging studies primarily using finger-tapping tasks.  ...  These studies suggest a close connection between sensory and motor processing of rhythm, with no apparent distinction between the two functions.  ...  Conflicts of Interest: The authors declare no conflicts of interest.  ...

Evoking plasticity through sensory stimulation: Implications for learning and rehabilitation

Hubert R. Dinse, Martin Tegenthoff
2015 e-Neuroforum  
It is generally agreed that processes allowing modification of synaptic efficacy are the neural substrates for learning.  ...  However, the lack of adequate input stimuli for the induction of LTP and LTD in humans has hindered direct evaluation of the impact of such protocols on human behaviour.  ...  In this experiment, the fingertip of the right index finger was repetitively stimulated with short cutaneous taps, which were transmitted to the skin via a small movable membrane.  ...

Laura Avanzino, Elisa Pelosin, Davide Martino, Giovanni Abbruzzese, Natasha M. Maurits
2013 PLoS ONE  
Fourteen patients with PD and twelve matched healthy volunteers were asked to tap in synchrony with a metronome cue (SYNC) and then, when the tone stopped, to keep tapping, trying to maintain the same  ...  rhythm (CONT-EXE) or to imagine tapping at the same rhythm, rather than actually performing it (CONT-MI).  ...  Structural and functional connectivity in parietofrontal pathways, both ipsi-and contralateral to the lesion, determines neural modulation associated with grasping imagery after stroke [61] .  ...

Does motor imagery share neural networks with executed movement: a multivariate fMRI analysis

Nikhil Sharma, Jean-Claude Baron
2013 Frontiers in Human Neuroscience  
Motor imagery (MI) is the mental rehearsal of a motor first person action-representation. There is interest in using MI to access the motor network after stroke.  ...  Here we use multivariate analysis (tensor independent component analysis-TICA) to map the array of neural networks involved during MI and EM.  ...  The duration of the finger tapping exercise varied and the subject had to confirm their position at the end of each block.  ...

Motor simulation theories of musical beat perception

Jessica M. Ross, John R. Iversen, Ramesh Balasubramaniam
2016 Neurocase  
The motor system is active during the perception of rhythms, but is such motor activity merely a sign of unexecuted motor planning, or does it play a causal role in shaping the perception of rhythm?  ...  Brain stimulation studies have the potential to conclusively test if the motor system plays a causal role in beat perception and ground theories to their neural underpinnings. ARTICLE HISTORY  ...  Analyses of finger tapping movements that are synchronized with an auditory rhythm demonstrate that taps often temporally precede the beat, an effect called negative mean asynchrony; humans spontaneously  ...
