    • The antidepressant effect of intermittent theta burst stimulation (iTBS): study protocol for a randomized double-blind sham-controlled trial 

      Ørbo, Marte Christine; Grønli, Ole Kristian; Larsen, Camilla; Vangberg, Torgil Riise; Friborg, Oddgeir; Turi, Zsolt; Mittner, Matthias Bodo; Csifcsak, Gabor; Aslaksen, Per M (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-02)
      Background Intermittent theta burst stimulation (iTBS) when applied over the left dorsolateral prefrontal cortex (DLPFC) has been shown to be equally effective and safe to treat depression compared to traditional repetitive transcranial magnetic stimulation (rTMS) paradigms. This protocol describes a funded single-centre, double-blind, randomized placebo-controlled, clinical trial to investigate ...

    • Blinding is compromised for transcranial direct current stimulation at 1 mA for 20 min in young healthy adults 

      Turi, Zsolt; Csifcsak, Gabor; Boayue, Nya Mehnwolo; Aslaksen, Per M; Antal, Andrea; Paulus, Walter; Groot, Josephine; Hawkins, Guy E.; Opitz, Alexander; Thielscher, Axel; Mittner, Matthias (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-03-19)
      Transcranial direct current stimulation (tDCS) is a non‐invasive brain stimulation method that is frequently used to study cortical excitability changes and their impact on cognitive functions in humans. While most stimulators are capable of operating in double‐blind mode, the amount of discomfort experienced during tDCS may break blinding. Therefore, specifically designed sham stimulation protocols ...

    • Commentary: Transcranial stimulation of the frontal lobes increases propensity of mind-wandering without changing meta-awareness

    • Data from ‘Placebo Enhances Reward Learning in Healthy Individuals’ 

      Turi, Zsolt; Antal, Andrea; Paulus, Walter; Mittner, Matthias (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-04-20)
      This dataset contains three repeated measures of a standard reward-based reinforcement-learning task from 29 healthy male individuals who participated in three experimental sessions exploring cognitive placebo effects on reward learning. The dataset includes behavioural data (accuracy, reaction times) during learning and transfer, estimates of model-free computational analysis, self-reported arousal ...

    • Increasing propensity to mind‐wander by transcranial direct current stimulation? A registered report 

      Boayue, Nya Mehnwolo; Csifcsak, Gabor; Aslaksen, Per M; Turi, Zsolt; Antal, Andrea; Groot, Josephine Maria; Hawkins, Guy E.; Forstmann, Birte U.; Opitz, Alexander; Thielscher, Axel; Mittner, Matthias (Journal article; Tidsskriftartikkel, 2019-01-24)
      Transcranial direct current stimulation (tDCS) has been proposed to be able to modulate different cognitive functions. However, recent meta‐analyses conclude that its efficacy is still in question. Recently, an increase in subjects’ propensity to mind‐wander has been reported as a consequence of anodal stimulation of the left dorsolateral prefrontal cortex (Axelrod et al., Proceedings of the National ...

    • Selecting stimulation intensity in repetitive transcranial magnetic stimulation studies: A systematic review between 1991 and 2020 

      Turi, Zsolt; Lenz, Maximilian; Paulus, Walter; Mittner, Matthias; Vlachos, Andreas (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-22)
      Repetitive transcranial magnetic stimulation (rTMS) is an increasingly used, non-invasive brain stimulation technique in neuroscience research and clinical practice with a broad spectrum of suggested applications. Among other parameters, the choice of stimulus intensity and intracranial electric field strength substantially impacts rTMS outcome. This review provides a systematic overview of the ...

    • Short-lived Alpha Power Suppression Induced by Low-intensity Arrhythmic rTMS 

      Zmeykina, Elina; Mittner, Matthias; Paulus, Walter; Turi, Zsolt (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-02)
      This study was conducted to provide a better understanding of the role of electric field strength in the production of aftereffects in resting state scalp electroencephalography by repetitive transcranial magnetic stimulation (rTMS) in humans. We conducted two separate experiments in which we applied rTMS over the left parietal-occipital region. Prospective electric field simulation guided the choice ...

    • Theta-gamma cross-frequency transcranial alternating current stimulation over the trough impairs cognitive control 

      Turi, Zsolt; Mittner, Matthias; Lehr, Albert; Bürger, H; Antal, Andrea; Paulus, Walter (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-15)
      Cognitive control is a mental process, which underlies adaptive goal-directed decisions. Previous studies have linked cognitive control to electrophysiological fluctuations in the theta band and theta-gamma cross-frequency coupling (CFC) arising from the cingulate and frontal cortices. Yet, to date the behavioral consequences of different forms of theta-gamma CFC remain elusive. Here, we studied the ...

    • Weak rTMS-induced electric fields produce neural entrainment in humans 

      Zmeykina, Elina; Mittner, Matthias; Paulus, Walter; Turi, Zsolt (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-20)
      Repetitive transcranial magnetic stimulation (rTMS) is a potent tool for modulating endogenous oscillations in humans. The current standard method for rTMS defines the stimulation intensity based on the evoked liminal response in the visual or motor system (e.g., resting motor threshold). The key limitation of the current approach is that the magnitude of the resulting electric field remains elusive. ...
