Self-relevant stimuli seem to automatically draw attention, but it is unclear whether this comes at a cost for processing subsequent stimuli, and whether the effect is depending on one’s mental state (i.e. depression). To address this question, we performed two experiments. In Experiment 1, 45 participants were to report two words (T1 and T2) in an...

Article
The ability to inhibit behavior is crucial for adaptation in a fast changing environment and is commonly studied with the stop signal task. Current EEG research mainly focuses on the N200 and P300 ERPs and corresponding activity in the theta and delta frequency range, thereby leaving us with a limited understanding of the mechanisms of response inh...
Conference Paper
Obesity is associated with brain atrophy and deficits in the executive functions (EF). Here, we compared the performance of 36 obese and 15 normal weight control subjects in a cognitive test battery covering four components of the EFs; conflict monitoring (Stroop task), working memory updating (N-back task), motor inhibition (Go/NoGo task), and set...
Article
Typical consequences in schizophrenia are work absence and early retirement. Such poor every day activities are associated with executive dysfunctioning. Under healthy conditions, successful executive functioning is associated to increased frontal-midline theta oscillations. Such event-related modulations are related to enhanced coupling between ne...
Conference Paper
Obesity has been shown to be associated with deficits in executive functioning. Here, a randomised-controlled trial is introduced that tests the effects of a computerised cognitive training of the executive functions and its mediation effects on conventional exercise and dieting programs for obese individuals.
Article
Full-text available
Frontal-midline (fm) theta oscillations as measured via the electroencephalogram (EEG) have been suggested as neural “working language” of executive functioning. Their power has been shown to increase when cognitive processing or task performance is enhanced. Thus, the question arises whether learning to increase fm-theta amplitudes would functiona...
Article
Full-text available
There has been a lively debate whether conceptual representations of actions or scenes follow a left-to-right spatial transient when participants depict such events or scenes. It was even suggested that conceptualizing the agent on the left side represents a universal. We review the current literature with an emphasis on event representation and on...
Article
Full-text available
Humans differ in their ability to learn how to control their own brain activity by neurofeedback. However, neural mechanisms underlying these inter-individual differences, which may determine training success and associated cognitive enhancement, are not well-understood. Here, it is asked whether neurofeedback success of frontal-midline (fm) theta,...
Article
Conflict monitoring and motor inhibition are engaged in the performance of complex tasks. The midcingulate cortex (MCC) has been suggested to detect conflicts, whereas the right inferior frontal cortex (IFC) seems to be of relevance for the inhibition process. The current experiment investigates the neural underpinnings of their interplay via a mod...

Full-text available
The midcingulate cortex (MCC; often somewhat imprecisely referred to as dorsal or cognitive part of the anterior cingulate cortex or dACC) is a core region contributing to cognitive control. Neuroanatomical deviations in the midcingulate region have been observed in a variety of mental disorders. Even in healthy subjects a high degree of morphologi...
Article
Response inhibition paradigms, as for example stop signal and go/no-go tasks, are often used to study cognitive control processes. Because of the apparent demand to stop a motor reaction, the electrophysiological responses evoked by stop and no-go trials have sometimes likewise been interpreted as indicators of inhibitory processes. Recent research...

Despite a growing number of studies, the neurophysiology of adult vocabulary acquisition is still poorly understood. One reason is that paradigms that can easily be combined with neuroscientfic methods are rare. Here, we tested the efficiency of two paradigms for vocabulary (re-) acquisition, and compared the learning of novel words for actions and...

Current theoretical positions assume that action-related word meanings are established by functional connections between perisylvian language areas and the motor cortex (MC) according to Hebb's associative learning principle. To test this assumption, we probed the functional relevance of the left MC for learning of a novel action word vocabulary by...
Article
Conflict and inhibition are considered to exert strong influences on the neurophysiological N200 and P300 brain responses as evoked in go/nogo and stop-signal tasks. In order to separate their underlying neural and functional mechanisms, the current experiment manipulated both conflict and inhibition. To do so, the go/nogo and stop-signal tasks wer...

This research aimed to increase our insights into the neural mechanisms underlying recovery from prefrontal lobe damage, including a new neuropsychological assessment tool and advanced electrophysiological measures of human cognition for informing and guiding functional recovery of prefrontal lesion patients. In this context, the present project addressed two main questions: (a) whether the apparently normal cognitive performance often observed in unilateral prefrontal lesion patients could be explained by functional compensation by the intact homologous frontal cortex; and (b) whether recovery and compensation of prefrontal functions could be best explained from a dynamic (rather than static) model of neural plasticity. To meet these aims, we developed a new testing procedure that integrates state-of-the-art analyses of the electroencephalogram (EEG) with a computational model of human cognition based on a hierarchy of control processes in prefrontal cortex (Koechlin & Summerfield, 2007). http://www.tv3.cat/marato/projectes_financats_2010.htm http://www.tv3.cat/marato/docs/simposiums/marato2016/memoria/eng/DrBarcelo.pdf
