Prestimulus frontal midline theta reflects increased cognitive control during spontaneous lapses of attention
PSYCHOLOGY. WP BRP. Издательский дом НИУ ВШЭ , 2014. No. WP BRP 27/PSY/2014.
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 to fluctuation in cognitive control; this aspect has not been previously addressed in literature. Specifically, it has not been studied whether performance errors can result from conflicts with spontaneous internally generated task-unrelated processes. In the present study, modulation of prestimulus brain activity in relation to spontaneous performance errors was studied during the auditory condensation task. Frontal midline theta (FMT) power, which is an indicator of cognitive control system activation, was found to be significantly higher before incorrect responses than before correct ones. Relative increase in FMT power before incorrect responses was positively correlated with Strength of excitation (STI questionnaire) and negatively correlated with the percentage of errors and with correct-to-error response time ratio. These findings allow us to suggest that the increase in the prestimulus FMT power before incorrect responses under the condensation task was at least partly related to the adjustment of the cognitive control system and conflict regulation. We speculate that the conflict may arise from interference between task-related and task-unrelated processes such as mind wandering.

The causes of everyday errors made by most people remain largely unknown. In order to investigate spontaneous lapses in attentional processing a new task was designed. This task creates an increased attentional load because it is based on impeded decision making involving both stimuli feature binding and response selection. Participants made errors in 9.6 ± ...

The state of mind wandering is related to complete or partial detachment of attention from external information. Under this state, attention switches from the ongoing primary task towards unrelated thoughts, fantasies and feelings. Current understanding of the role of cognitive control in the initiation and sustaining the state of mind wandering is ambiguous, and specific ...

Successful performance in complex tasks depends upon the functioning of the cognitive control system involving the maintenance of sustained attention, retention and activation of task rules, as well as the inhibition of preliminary responses. Failure of any of these functions can lead to performance errors. In this study, we investigated behavioral data obtained from participants ...

Mind-wandering is a specific state of consciousness, during which attention fully or partially switches from perception of external sensory information to inner mental processes. This state is largely spontaneous, and its content usually cannot be consciously controlled. Thoughts during mind wandering are generated by endogenous mental processes focusing on goals of high personal significance. These ...

Source-space EEG neurofeedback links subjective experience with brain activity during effortless awareness meditation
, , et al., Neuroimage 2016 Vol. 4 C No. 3
Meditation is increasingly showing beneficial effects for psychiatric disorders. However, learning to meditate is not straightforward as there are no easily discernible outward signs of performance and thus no direct feedback is possible. As meditation has been found to correlate with posterior cingulate cortex (PCC) activity, we tested whether source-space EEG neurofeedback from the PCC followed the subjective experience of effortless awareness ...

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 ...

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 ...

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 ...

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). ...

This article provides a short overview of the various studies devoted to executive functions. Executive functions are “a set of general-purpose control mechanisms, often linked to the prefrontal cortex of the brain, that regulate the dynamics of human cognition and action” (Miyake, Friedman, 2012). Executive functions have gained popularity as a way to decompose into ...

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 ...

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 ...

In tasks involving response choice based on certain stimulus-to-response mappings, at least two stages of information processing may be involved: (1) formation of sensory stimulus object representations leading to stimulus identification, and (2) application of stimulus-to-response mappings (i.e. “task rules”) to these representations leading to response selection. Most of the research done in this area ...
