    • 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

    • Effects of transcranial direct current stimulation for treating depression: A modeling study 

      Csifcsak, Gabor; Boayue, Nya Mehnwolo; Puonti, Oula; Thielscher, Axel; Mittner, Matthias (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-02-28)
      <p><i>Background</i>: Transcranial direct current stimulation (tDCS) above the left dorsolateral prefrontal cortex (lDLPFC) has been widely used to improve symptoms of major depressive disorder (MDD). However, the effects of different stimulation protocols in the entire frontal lobe have not been investigated in a large sample including patient data.</p> <p><i>Methods</i>: We used 38 head ...

    • Head models of healthy and depressed adults for simulating the electric fields of non-invasive electric brain stimulation [version 2; referees: 2 approved] 

      Boayue, Nya Mehnwolo; Csifcsak, Gabor; Puonti, Oula; Thielscher, Axel; Mittner, Matthias (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-06-06)
      During the past decade, it became clear that the electric field elicited by non-invasive brain stimulation (NIBS) techniques such as transcranial direct current stimulation (tDCS) and transcranial magnetic stimulation (TMS) are substantially influenced by variations in individual head and brain anatomy. In addition to structural variations in the healthy, several psychiatric disorders are characterized ...

    • 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 ...
