EEG oscillatory patterns are associated with error prediction during music performance and are altered in musician's dystonia
, , et al., Neuroimage 2011 Vol. 55 No. 4 P. 1791-1803
Skilled performance requires the ability to monitor ongoing behavior, detect errors in advance and modify the performance accordingly. The acquisition of fast predictive mechanisms might be possible due to the extensive training characterizing expertise performance. Recent EEG studies on piano performance reported a negative event-related potential (ERP) triggered in the ACC 70 ms before performance errors (pitch errors due to incorrect keypress). ...

Error signals in the subthalamic nucleus are related to post-error slowing in patients with Parkinson's disease
, , et al., Cortex 2014 Vol. 60 P. 103-120
Error monitoring is essential for optimizing motor behavior. It has been linked to the medial frontal cortex, in particular to the anterior midcingulate cortex (aMCC). The aMCC subserves its performance-monitoring function in interaction with the basal ganglia (BG) circuits, as has been demonstrated in patients suffering from BG lesions or from Parkinson's disease (PD). The subthalamic nucleus (STN) has been assumed an ...

Cardiac afferent activity modulates early neural signature of error detection during skilled performance
, , et al., Neuroimage 2019 Vol. 199 P. 704-717
Behavioral adaptations during performance rely on predicting and evaluating the consequences of our actions through action monitoring. Previous studies revealed that proprioceptive and exteroceptive signals contribute to error-monitoring processes, which are implemented in the posterior medial frontal cortex. Interestingly, errors also trigger changes in autonomic nervous system activity such as pupil dilation or heartbeat deceleration. Yet, the contribution ...

Objective. Brain-computer interface (BCI) systems are known to be vulnerable to variabilities in background states of a user. Usually, no detailed information on these states is available even during the training stage. Thus there is a need in a method which is capable of taking background states into account in an unsupervised way. Approach. We ...

Neurofeedback learning modifies the incidence rate of alpha spindles, but not their duration and amplitude
, , et al., Scientific Reports 2017
Although the first experiments on alpha-neurofeedback date back nearly six decades ago, when Joseph Kamiya reported successful operant conditioning of alpha-rhythm in humans, the effectiveness of this paradigm in various experimental and clinical settings is still a matter of debate. Here, we investigated the changes in EEG patterns during a continuously administered neurofeedback of P4 ...

Arthrogryposis is one of the most severe congenital abnormalities of the musculoskeletal system characterized by 2 or more contractures of the large joints, muscle and anterior grey column pathology. One of the main problems making selfcare limited or impossible for the patients is an absence of the active movements in the joints of the upper ...

Early and parallel processing of pragmatic and semantic information in speech acts: neurophysiological evidence
, , , Frontiers in Human Neuroscience 2013 Vol. 7 No. 86 P. 1-13
Although language is a tool for communication, most research in the neuroscience of language has focused on studying words and sentences, while little is known about the brain mechanisms of speech acts, or communicative functions, for which words and sentences are used as tools. Here the neural processing of two types of speech acts, Naming ...

Can language-action links explain language laterality? An ERP study of perceptual and articulatory learning of novel pseudowords
, , , Cortex 2012 Vol. 48 No. 7 P. 871-881
We here investigate whether the well-known laterality of spoken language to the dominant left hemisphere could be explained by the learning of sensorimotor links between a word's articulatory program and its corresponding sound structure. Human-specific asymmetry of acoustic-articulatory connectivity is evident structurally, at the neuroanatomical level, in the arcuate fascicle, which connects superior-temporal and frontal ...

The goal of the present study was to investigate the interaction between different senses of polysemous nouns (metonymies and metaphors) and different meanings of homonyms using the method of event-related potentials (ERPs) and a priming paradigm. Participants read two-word phrases containing ambiguous words and made a sensicality judgment. Phrases with polysemes highlighted their literal sense ...

Neural dynamics of inflectional and derivational processing in spoken word comprehension: Laterality and automaticity
, , , Frontiers in Human Neuroscience 2013 Vol. 7 No. 759 P. 1-15
Rapid and automatic processing of grammatical complexity is argued to take place during speech comprehension, engaging a left-lateralized fronto-temporal language network. Here we address how neural activity in these regions is modulated by the grammatical properties of spoken words. We used combined magneto- and electroencephalography to delineate the spatiotemporal patterns of activity that support the ...

Performance errors are well studied under conditions of increased demands for motor inhibition; within this framework, errors are considered to be manifestations of motor conflicts between mutually exclusive responses to stimuli presented. However, tasks that require prolonged exertion of sustained attention and complex stimulus-response mapping may involve somewhat different internal causes of performance errors related ...

We investigated neural distinctions between inflectional and derivational morphology and their interaction with lexical frequency using the mismatch negativity (MMN), an established neurophysiological index of experience-dependent linguistic memory traces and automatic syntactic processing. We presented our electroencephalography (EEG) study participants with derived and inflected words of variable lexical frequencies against their monomorphemic base forms in ...

Cortical networks for reference-frame processing are shared by language and spatial navigation systems
, , Neuroimage 2017 Vol. 161 P. 120-133
To help us live in the three-dimensional world, our brain integrates incoming spatial information into reference frames, which are based either on our own body (egocentric) or independent from it (allocentric). Such frames, however, may be crucial not only when interacting with the visual world, but also in language comprehension, since even the simplest utterance ...

The article presents an empirical study of the relationship between the psychological well-being of a person and his/ her inner dialogical activity, measured as the frequency of dialogical practices of praying and meditating. The result showed that the frequency of dialogical practices weakly positively correlates with all indicators of psychological well-being in the samples of ...

More than a decade of neuroimaging research has established that several distinct brain networks are consistently recruited during social punishment, that is, the propensity of cooperative individuals to spend some of their resources penalizing norm violators. Studies in behavioral economics have shown that social punishment can explain why genetically unrelated individuals are often able to ...

Neuronal oscillations are ubiquitous in the human brain and are implicated in virtually all brain functions. Although they can be described by a prominent peak in the power spectrum, their waveform is not necessarily sinusoidal and shows rather complex morphology. Both frequency and temporal descriptions of such non-sinusoidal neuronal oscillations can be utilized. However, in ...

Meditation is a consciousness state associated with specific physiological and neural correlates. Numerous investigations of these correlates reported controversial results which prevented a consistent depiction of the underlying neurophysiological processes. Here we investigated the dynamics of multiple neurophysiological indicators during a staged meditation session. We measured the physiological changes at rest and during the guided ...
