This study explores the impact of anodal tDCS on WM deficits induced by stress. We know from previous research that stress conditions lead to deficits in WM performance by reducing WM-related activity in the brain. Specifically, the dorsolateral prefrontal cortex (dlPFC) is heavily involved in WM processes, and the ventromedial prefrontal cortex (vmPFC) plays a crucial role in stress regulation and has been associated with positive emotions during stress recovery. Given these findings, we aimed to determine the most effective stimulation region for alleviating WM deficits caused by psychologic

Individuals regularly have to decide upon motor actions to be performed. Motor decision-making involves the selection between and specification of potential action plans (Cisek, 2007) and necessitates the integration of perceptual, cognitive, and motor processes (Cisek & Kalaska, 2010; van Ede & Nobre, 2023). The influence of cognitive load during decision-making on subsequent motor action execution remains largely unexplored (Gordon et al., 2021). This study investigates the influence of working memory (WM) load on goal-directed pointing movements, hypothesizing that increased WM load

Physical Exercise (PE) is widely acknowledged for its positive impact on cognition and specifically on short-term memory. However, the precise neurophysiological mechanisms of performance improvements are unclear. We developed an MEG-compatible pedal exercises – mimicking walking – to explore PE’s impact on working memory (WM). In simultaneous MEG/EEG recordings participants carried out an N-back task with varying WM loads across blocks and either rested or walked during 2-min-breaks between blocks. PE improved target detection, heightened EEG-spindle activity. MEG ripples (80-150Hz) displayed
