Накратко на български

Възможността за подобряване на вниманието чрез стимулиране на мозъка се тества при задачи като шофирането. Това помага да се разбере как да се ограничи разсейването и да се подпомогнат хора с дефицит на вниманието без лекарства.

Oscillatory long-Range Coherence in Attention

Attention -the ability to focus selectively on task relevant information and resist distraction- plays a critical role in many everyday life situations, such as in school or while driving. With an almost constant stream of information reaching us through smart phones and computers, our world becomes increasingly distracting, requiring enhanced attentional capabilities. This calls for new approaches to improve attention, also benefiting patients populations suffering from attention deficits. Is it possible to safely improve attention without medication? And how does the brain actually guides attention and resist distractions? Our research project set out to answer these questions by applying a novel brain stimulation technique, transcranial alternating current stimulation (tACS). In the first study, we assessed the effects of stimulation on spatial attention performance, while simultaneously measuring neural activity using electroencephalogram (EEG). Unfortunately, we did not find the expected effects of stimulation on attention or neural activity. Because this finding contradicts previous findings, we currently are unsure whether it is possible to modulate spatial attention with tACS. In a second study we focused on manipulating vigilant attention instead of spatial attention. This kind of attention is particularly important in settings that require you to focus attention for a long time on an generally uneventful task, such as driving a car or air traffic control. In this study we found a frequency-specific effect on performance. Although further research is needed, this finding offers promising tools to improve vigilant attention. Taken together, in our research project we were able to modulate vigilant attention, but not spatial attention. In the future, these initial results could lead to methods to improve (vigilant) attention and thereby prevent the harmful effects of deteriorating attention.

Цел на проекта

Attention -the ability to focus selectively on task relevant information and resist distraction- plays a critical role in many everyday life situations, such as in school or while driving. With an almost constant stream of information reaching us through smart phones and computers, our world becomes increasingly distracting, requiring enhanced attentional capabilities. This calls for new approaches to improve attention, also benefiting patients populations suffering from attention deficits. Is it possible to safely improve attention without medication? And how does the brain actually guides attention and resist distractions? The proposed research aims to answer these questions by combining a novel brain stimulation technique, transcranial alternating current stimulation (tACS) with state of the art neuroimaging methods. It will specifically test the intriguing hypothesis that attention can be enhanced by synchronizing rhythmic activity between two brain regions previously shown to be involved in attention. In the first study I will assess the effects of stimulation on attention performance, while simultaneously measuring neural activity using electroencephalogram (EEG). This will allow me to determine to what extent tACS can improve attention and investigate the causal role of neural oscillations in attention. In the second study, tACS will be combined with functional magnetic resonance imaging (fMRI) allowing to bridge the literature on neural oscillations (derived from EEG research) and attention networks (derived from fMRI research). Specifically, it will provide novel insights into the exact neural network subserving oscillatory activity associated with attention. Taken together, this project will not only investigate an innovative way to improve attention, with important implication for future clinical studies, but will also have a major contribution to cognitive neuroscience theories of attention.
