BACKGROUND In the past decade research has shown that continuous (cTBS) and intermittent theta burst stimulation (iTBS) alter neuronal excitability levels in the primary motor cortex. OBJECTIVE Quantitatively review the magnitude and time course on cortical excitability of cTBS and iTBS. METHODS Sixty-four TBS studies published between January 2005 and(More)
Research on the hedonic value of food has been important in understanding the motivational and emotional correlates of normal and abnormal eating behaviour. The aim of the present study was to explore associations between hemispheric asymmetries recorded during resting state electroencephalogram (EEG) and hedonic valuation of food. Healthy adult volunteers(More)
The assumption that transcranial alternating current stimulation (tACS) enhances perceptual and cognitive ability in healthy volunteers by exposing the brain to exogenous oscillatory electric fields is increasingly finding its way into society and commercial parties. The aim of the present study is to quantify the effects of exogenous oscillatory electric(More)
BACKGROUND Theta oscillations in the electroencephalogram (EEG) are associated with learning and behavioral adaptation. OBJECTIVE To investigate the effects of theta transcranial alternating current stimulation (tACS) applied to the frontal cortex on reversal learning. METHODS Healthy volunteers participated in a sham-controlled between subjects design.(More)
OBJECTIVE Paired associative stimulation (PAS) has been used to study normal and abnormal cortical plasticity. However, a normative review of PAS effects has not been provided so far. To this end, the magnitude and time course of PAS protocols was systematically evaluated here. METHODS A literature search in PubMed using the search term paired associative(More)
The role of primary motor cortex (M1) in the control of hand movements is still unclear. Functional magnetic resonance imaging (fMRI) studies of unimanual performance reported a relationship between level of precision of a motor task and additional ipsilateral M1 (iM1) activation. In the present study, we determined whether the demand on accuracy of a(More)
According to Kalisch et al., adopting a cognitive positive appraisal style promotes internal bodily homeostasis and acts as a safeguard against the detrimental effects of stress. Here we will discuss results from recent noninvasive brain stimulation studies in humans to illustrate that homeostatic plasticity provides a neural mechanistic account for the(More)
