Previous studies have claimed that weak transcranial direct current stimulation (tDCS) induces persisting excitability changes in the human motor cortex that can be more pronounced than cortical modulation induced by transcranial magnetic stimulation, but there are no studies that have evaluated the effects of tDCS on working memory. Our aim was to(More)
OBJECTIVES Cognitive impairment is a common feature in Parkinson's disease (PD) and is an important predictor of quality of life. Past studies showed that some aspects of cognition, such as working memory, can be enhanced following dopaminergic therapy and transcranial magnetic stimulation. The aim of our study was to investigate whether another form of(More)
The combination of brain stimulation techniques like transcranial magnetic stimulation (TMS) with CNS active drugs in humans now offers a unique opportunity to explore the physiologic effects of these substances in vivo in the human brain. Motor threshold, motor evoked potential size, motor evoked potential intensity curves, cortical silent period,(More)
Chronic pain resulting from injury of the peripheral or central nervous system may be associated with a significant dysfunction of extensive neural networks. Noninvasive stimulation techniques, such as repetitive transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS) may be suitable to treat chronic pain as they can act(More)
Emergent game formats, such as machinima, that use game worlds as expressive 3D performance spaces have new expressive powers with an increase of the quality of their underlying graphic and animation systems. Nevertheless, they still lack intuitive control mechanisms. Set direction and acting are limited by tools that were designed to create and play video(More)
We have developed an embodied puppet interface that translates a player's body movements to a virtual character, thus enabling the player to have a fine grained and personalized control of the avatar. To test the efficacy and short-term effects of this control interface, we developed a two-part experiment, where the performance of users controlling an(More)
