The metacontrol of event segmentation—A neurophysiological and behavioral perspective

Xianzhen Zhou, Foroogh Ghorbani, Veit Roessner, Bernhard Hommel, more

Human Brain Mapping > 45 > 11 > n/a - n/a

During our everyday life, the constant flow of information is divided into discrete events, a process conceptualized in Event Segmentation Theory (EST). How people perform event segmentation and the resulting granularity of encapsulated segments likely depends on their metacontrol style. Yet, the underlying neural mechanisms remain undetermined. The current study examines how the metacontrol style...

Interindividual aperiodic resting‐state EEG activity predicts cognitive‐control styles

Yu Pi, Jimin Yan, Charlotte Pscherer, Shudan Gao, more

Psychophysiology > 61 > 8 > n/a - n/a

The ability to find the right balance between more persistent and more flexible cognitive‐control styles is known as “metacontrol.” Recent findings suggest a relevance of aperiodic EEG activity and task conditions that are likely to elicit a specific metacontrol style. Here we investigated whether individual differences in aperiodic EEG activity obtained off‐task (during resting state) predict individual...

The ReCoDe addiction research consortium: Losing and regaining control over drug intake—Findings and future perspectives

Rainer Spanagel, Patrick Bach, Tobias Banaschewski, Anne Beck, more

Addiction Biology > 29 > 7 > n/a - n/a

Substance use disorders (SUDs) are seen as a continuum ranging from goal‐directed and hedonic drug use to loss of control over drug intake with aversive consequences for mental and physical health and social functioning. The main goals of our interdisciplinary German collaborative research centre on Losing and Regaining Control over Drug Intake (ReCoDe) are (i) to study triggers (drug cues, stressors,...

Neural representations of statistical and rule‐based predictions in Gilles de la Tourette syndrome

Adam Takacs, Eszter Toth‐Faber, Lina Schubert, Zsanett Tarnok, more

Human Brain Mapping > 45 > 8 > n/a - n/a

Gilles de la Tourette syndrome (GTS) is a disorder characterised by motor and vocal tics, which may represent habitual actions as a result of enhanced learning of associations between stimuli and responses (S‐R). In this study, we investigated how adults with GTS and healthy controls (HC) learn two types of regularities in a sequence: statistics (non‐adjacent probabilities) and rules (predefined order)...

Response stopping under conflict: The integrative role of representational dynamics associated with the insular cortex

Filippo Ghin, Elena Eggert, Negin Gholamipourbarogh, Nasibeh Talebi, more

Human Brain Mapping > 45 > 6 > n/a - n/a

Coping with distracting inputs during goal‐directed behavior is a common challenge, especially when stopping ongoing responses. The neural basis for this remains debated. Our study explores this using a conflict‐modulation Stop Signal task, integrating group independent component analysis (group‐ICA), multivariate pattern analysis (MVPA), and EEG source localization analysis. Consistent with previous...

Rethinking Movement Disorders

Alexander Münchau, Christine Klein, Christian Beste

Movement Disorders > 39 > 3 > 472 - 484

At present, clinical practice and research in movement disorders (MDs) focus on the “normalization” of altered movements. In this review, rather than concentrating on problems and burdens people with MDs undoubtedly have, we highlight their hidden potentials. Starting with current definitions of Parkinson's disease (PD), dystonia, chorea, and tics, we outline that solely conceiving these phenomena...

Alpha and theta band activity share information relevant to proactive and reactive control during conflict‐modulated response inhibition

Charlotte Pscherer, Paul Wendiggensen, Moritz Mückschel, Annet Bluschke, more

Human Brain Mapping > 44 > 17 > 5936 - 5952

Response inhibition is an important instance of cognitive control and can be complicated by perceptual conflict. The neurophysiological mechanisms underlying these processes are still not understood. Especially the relationship between neural processes directly preceding cognitive control (proactive control) and processes underlying cognitive control (reactive control) has not been examined although...

Regaining control over opioid use? The potential application of auricular transcutaneous vagus nerve stimulation to improve opioid treatment in China

Lorenza Colzato, Julia Elmers, Xiaolei Xu, Qiang Zhou, more

Addiction Biology > 28 > 11 > n/a - n/a

Opioid use disorder (OUD) is a critical problem in China and is accompanied by depression and deficits in cognitive control. In China, the most successful intervention for OUD is the community drug rehabilitation where methadone maintenance treatment (MMT) plays a key role. Even though methadone for the treatment of OUD can be helpful, it can cause severe somatic side‐effects, which limit its effectivity...

The functional connectome of 3,4‐methyldioxymethamphetamine‐related declarative memory impairments

Rebecca C. Coray, Josua Zimmermann, Amelie Haugg, Markus R. Baumgartner, more

Human Brain Mapping > 44 > 15 > 5079 - 5094

The chronic intake of 3,4‐methylenedioxymethamphetamine (MDMA, “ecstasy”) bears a strong risk for sustained declarative memory impairments. Although such memory deficits have been repeatedly reported, their neurofunctional origin remains elusive. Therefore, we here investigate the neuronal basis of altered declarative memory in recurrent MDMA users at the level of brain connectivity. We examined a...

Deep learning on independent spatial EEG activity patterns delineates time windows relevant for response inhibition

Negin Gholamipourbarogh, Amirali Vahid, Moritz Mückschel, Christian Beste

Psychophysiology > 60 > 10 > n/a - n/a

Inhibitory control processes are an important aspect of executive functions and goal‐directed behavior. However, the mostly correlative nature of neurophysiological studies was not able to provide insights which aspects of neural dynamics can best predict whether an individual is confronted with a situation requiring the inhibition of a response. This is particularly the case when considering the...

Perception–Action Integration Is Altered in Functional Movement Disorders

Anne Weissbach, Josephine Moyé, Adam Takacs, Julius Verrel, more

Movement Disorders > 38 > 8 > 1399 - 1409

Background Although functional neurological movement disorders (FMD) are characterized by motor symptoms, sensory processing has also been shown to be disturbed. However, how the integration of perception and motor processes, essential for the control of goal‐directed behavior, is altered in patients with FMD is less clear. A detailed investigation of these processes is crucial to foster a better...

Automated Motor Tic Detection: A Machine Learning Approach

Nele Sophie Brügge, Gesine Marie Sallandt, Ronja Schappert, Frédéric Li, more

Movement Disorders > 38 > 7 > 1327 - 1335

Background Video‐based tic detection and scoring is useful to independently and objectively assess tic frequency and severity in patients with Tourette syndrome. In trained raters, interrater reliability is good. However, video ratings are time‐consuming and cumbersome, particularly in large‐scale studies. Therefore, we developed two machine learning (ML) algorithms for automatic tic detection. ...

Extra Movements in Healthy People: Challenging the Definition and Diagnostic Practice of Tic Disorders

Stefanie Bartha, Annet Bluschke, Tina Rawish, Kim E. R. Naumann, more

Annals of Neurology > 93 > 3 > 472 - 478

The occurrence of motor/vocal tics, that is, “extra movements” and/or “extra vocalizations,” is the leading diagnostic criterion for tic disorders. We show that extra movements are common also in healthy controls, so that a surplus of movements per se is not indicative of the presence of a tic disorder. This questions the usefulness of Diagnostic and Statistical Manual of Mental Disorders, 5th edition...

Evidence for independent representational contents in inhibitory control subprocesses associated with frontoparietal cortices

Negin Gholamipourbarogh, Filippo Ghin, Moritz Mückschel, Christian Frings, more

Human Brain Mapping > 44 > 3 > 1046 - 1061

Inhibitory control processes have intensively been studied in cognitive science for the past decades. Even though the neural dynamics underlying these processes are increasingly better understood, a critical open question is how the representational dynamics of the inhibitory control processes are modulated when engaging in response inhibition in a relatively automatic or a controlled mode. Against...

Posterior delta/theta EEG activity as an early signal of Stroop conflict detection

Céline C. Haciahmet, Christian Frings, Christian Beste, Alexander Münchau, more

Psychophysiology > 60 > 3 > n/a - n/a

The conflict monitoring theory postulates that conflict detection is initiated in the anterior cingulate cortex (ACC), indexed by midfrontal theta oscillations in the electroencephalogram (EEG). Recent research suggested that distractor detection (in the Eriksen flanker task) can be initiated relatively early by attentional control processes in the occipital lobe. Whether attentional control is also...

Perception‐action integration during inhibitory control is reflected in a concomitant multi‐region processing of specific codes in the neurophysiological signal

Negin Gholamipourbarogh, Astrid Prochnow, Christian Frings, Alexander Münchau, more

Psychophysiology > 60 > 2 > n/a - n/a

The integration of perception and action has long been studied in psychological science using overarching cognitive frameworks. Despite these being very successful in explaining perception‐action integration, little is known about its neurophysiological and especially the functional neuroanatomical foundations. It is unknown whether distinct brain structures are simultaneously involved in the processing...

Auricular transcutaneous vagus nerve stimulation for alcohol use disorder: A chance to improve treatment?

Anyla Konjusha, Lorenza Colzato, Filippo Ghin, Ann‐Kathrin Stock, more

Addiction Biology > 27 > 5 > n/a - n/a

Alcohol use disorder (AUD) is a relapsing–remitting condition characterized by excessive and/or continued alcohol consumption despite harmful consequences. New adjuvant tools, such as noninvasive brain stimulation techniques, might be helpful additions to conventional treatment approaches or even provide an alternative option for patients who fail to respond adequately to other treatment options....

Pandemic Tic‐like Behaviors Following Social Media Consumption

Theresa Paulus, Tobias Bäumer, Julius Verrel, Anne Weissbach, more

Movement Disorders > 36 > 12 > 2932 - 2935

Background Currently, there is a marked increase of young people with sudden onset of tic‐like behaviors (TLBs) resembling movements and vocalizations presented on social media videos as “Tourette's syndrome.” Objective To delineate clinical phenomenology of TLBs after social media exposure in comparison with clinical features of Tourette's syndrome. Methods We compared demographic and clinical...

Acute alcohol intoxication modulates the temporal dynamics of resting electroencephalography networks

Bastian Schiller, Markus Heinrichs, Christian Beste, Ann‐Kathrin Stock

Addiction Biology > 26 > 6 > n/a - n/a

This study aimed to provide a currently missing link between general intoxication‐induced changes in overall brain activity and the multiple cognitive control deficits typically observed during acute alcohol intoxication. For that purpose, we analyzed the effects of acute alcohol intoxication (1.1‰) on the four archetypal electroencephalography (EEG) resting networks (i.e., microstates A–D) and their...
