Acute alcohol intoxication and expectations reshape the spatiotemporal functional architecture of executive control

Ribordy Lambert, Farfalla ; Wicht, Corentin A. ; Mouthon, Michael ; Spierer, Lucas

In: NeuroImage, 2020, vol. 215, p. 116811

While the deleterious effects of acute ethyl alcohol intoxication on executive control are well-established, the underlying spatiotemporal brain mechanisms remain largely unresolved. In addition, since the effects of alcohol are noticeable to participants, isolating the effects of the substance from those related to expectations represents a major challenge. We addressed these issues using a...

Effects of continuous theta burst stimulation over the left DLPFC on mother tongue and second language production in late bilinguals: a behavioral and ERP study

Jost, Lea B. ; Pestalozzi, Maria I. ; Cazzoli, Dario ; Mouthon, Michael ; Müri, René M. ; Annoni, Jean‑Marie

In: Brain Topography, 2020, vol. 33, no. 4, p. 504–518

Clinical, neuroimaging, and non-invasive brain stimulation studies have associated the dorsolateral prefrontal cortex (DLPFC) with the multilingual language control system. Here, we investigated if this role is increased during the processing of the non- dominant language due to the higher cognitive/attentional demands. We used an inhibitory repetitive transcranial magnetic stimulation (rTMS)...

Training‐, muscle‐ and task‐specific up‐ and downregulation of cortical inhibitory processes

Taube, Wolfgang ; Gollhofer, Albert ; Lauber, Benedikt

In: European Journal of Neuroscience, 2020, vol. 51, no. 6, p. 1428–1440

Motor cortical contribution was shown to be important for balance control and for ballistic types of movements. However, little is known about the role of cortical inhibitory mechanisms and even less about long(er)‐term adaptations of these inhibitory processes. Therefore, the aim of the present study was to investigate the role of intracortical inhibition before and after four weeks of ...

Countermovement jump training is more effective than drop jump training in enhancing jump height in non-professional female volleyball players

Ruffieux, Jan ; Wälchli, Michael ; Kim, Kyung-Min ; Taube, Wolfgang

In: Frontiers in Physiology, 2020, vol. 11, p. -

The aim of the present study was to compare the effects of countermovement jump (CMJ) and drop jump (DJ) training on the volleyball-specific jumping ability of non-professional female volleyball players. For that purpose, 26 female volleyball players (15–32 years) were assigned to either a CMJ (20.4 ± 3.1 years, 171.0 ± 3.0 cm) or a DJ training group (22.0 ± 4.4 years, 168.2 ± 5.0 cm), ...

Effects of theta burst stimulation over the dorsolateral prefrontal cortex on language switching – A behavioral and ERP study

Pestalozzi, Maria I. ; Annoni, Jean-Marie ; Müri, René M. ; Jost, Lea B.

In: Brain and Language, 2020, vol. 205, p. 104775

This study investigated the role of the left dorsolateral prefrontal cortex (DLPFC) in language switching using theta burst stimulation (TBS) and electroencephalography in late bilinguals. After a sham-controlled baseline, participants received either excitatory or inhibitory TBS over the left DLPFC before conducting picture naming tasks in pure language blocks and a language switching...
