Non-invasive stimulation of the human striatum disrupts reinforcement learning of motor skills

Friedhelm Christoph Hummel, Takuya Morishita, Pierre Theopistos Vassiliadis, Elena Beanato, Esra Neufeld, Fabienne Windel, Maximilian Jonas Wessel, Traian Popa, Julie Duqué

Reinforcement feedback can improve motor learning, but the underlying brain mechanisms remain underexplored. In particular, the causal contribution of specific patterns of oscillatory activity within the human striatum is unknown. To address this question, ...

Noninvasive modulation of the hippocampal-entorhinal complex during spatial navigation in humans

Olaf Blanke, Friedhelm Christoph Hummel, Pierre Theopistos Vassiliadis, Elena Beanato, Esra Neufeld, Emanuela De Falco, Fabienne Windel, Maximilian Jonas Wessel, Traian Popa, Baptiste Gauthier

Because of the depth of the hippocampal-entorhinal complex (HC-EC) in the brain, understanding of its role in spatial navigation via neuromodulation was limited in humans. Here, we aimed to better elucidate this relationship in healthy volunteers, using tr ...

Noninvasive theta-burst stimulation of the human striatum enhances striatal activity and motor skill learning

Friedhelm Christoph Hummel, Takuya Morishita, Pablo Maceira Elvira, Pierre Theopistos Vassiliadis, Elena Beanato, Fabienne Windel, Esra Neufeld, Maximilian Jonas Wessel, Chang-Hyun Park, Traian Popa

The stimulation of deep brain structures has thus far only been possible with invasive methods. Transcranial electrical temporal interference stimulation (tTIS) is a novel, noninvasive technology that might overcome this limitation. The initial proof-of-co ...

MorphoSONIC: A morphologically structured intramembrane cavitation model reveals fiber-specific neuromodulation by ultrasound

Silvestro Micera, Esra Neufeld, Elena Vicari, Théo Lemaire

Low-Intensity Focused Ultrasound Stimulation (LIFUS) holds promise for the remote modulation of neural activity, but an incomplete mechanistic characterization hinders its clinical maturation. Here we developed a computational framework to model intramembr ...

Understanding ultrasound neuromodulation using a computationally efficient and interpretable model of intramembrane cavitation

Silvestro Micera, Théo Lemaire, Esra Neufeld

Objective. Low-intensity focused ultrasound stimulation (LIFUS) emerges as an attracting technology for noninvasive modulation of neural circuits, yet the underlying action mechanisms remain unclear. The neuronal intramembrane cavitation excitation (NICE) ...
