Fast adaptation to rule switching using neuronal surprise
In humans and animals, surprise is a physiological reaction to an unexpected event, but how surprise can be linked to plausible models of neuronal activity is an open problem. We propose a self-supervised spiking neural network model where a surprise signa ...
2024Customizing the human-avatar mapping based on EEG error related potentials during avatar-based interaction.
Olaf Blanke, José del Rocio Millán Ruiz, Ronan Boulic, Bruno Herbelin, Ricardo Andres Chavarriaga Lozano, Fumiaki Iwane
Objective. A key challenge of virtual reality (VR) applications is to maintain a reliable human-avatar mapping. Users may lose the sense of controlling (sense of agency), owning (sense of body ownership), or being located (sense of self-location) inside th ...
2024Unveiling the complexity of learning and decision-making
Reinforcement learning (RL) is crucial for learning to adapt to new environments. In RL, the prediction error is an important component that compares the expected and actual rewards. Dopamine plays a critical role in encoding these prediction errors. In my ...
EPFL2024Evaluating the Impact of Learner Control and Interactivity in Conversational Tutoring Systems for Persuasive Writing
Conversational tutoring systems (CTSs) offer a promising avenue for individualized learning support, especially in domains like persuasive writing. Although these systems have the potential to enhance the learning process, the specific role of learner cont ...
2024How to support students to develop coaching and peer teaching skills
Siara Ruth Isaac, Joelyn de Lima
Students learn more when they are actively engaged in the learning process. While hands-on activities, labs and projects are moments when students are active, the learning benefits can be amplified with coaching strategies. This activity will enable studen ...
EPFL2024DELMEP: a deep learning algorithm for automated annotation of motor evoked potential latencies
Friedhelm Christoph Hummel, Claudia Bigoni, Nima Taherinejad
The analysis of motor evoked potentials (MEPs) generated by transcranial magnetic stimulation (TMS) is crucial in research and clinical medical practice. MEPs are characterized by their latency and the treatment of a single patient may require the characte ...
NATURE PORTFOLIO2023A striatal circuit balances learned fear in the presence and absence of sensory cues
Ralf Schneggenburger, Olexiy Kochubey, Michael Kintscher
During fear learning, defensive behaviors like freezing need to be finely balanced in the presence or absence of threat-predicting cues (conditioned stimulus, CS). Nevertheless, the circuits underlying such balancing are largely unknown. Here, we investiga ...
eLIFE SCIENCES PUBL LTD2023Inferring individual evaluation criteria for reaching trajectories with obstacle avoidance from EEG signals
Aude Billard, José del Rocio Millán Ruiz, Fumiaki Iwane
During reaching actions, the human central nerve system (CNS) generates the trajectories that optimize effort and time. When there is an obstacle in the path, we make sure that our arm passes the obstacle with a sufficient margin. This comfort margin varie ...
Berlin2023Combination of Neurotechnologies Towards Personalized Neurorehabilitation for Stroke Patients
"Ensure healthy lives and promote well-being for all at all ages" is the third sustainable development goal for the United Nations Agenda of 2030. This doctoral thesis fully embodied this objective by targeting stroke, a leading cause of death and disabili ...
EPFL2023Plasticity of sensory representations in the posterior insular cortex during fear learning
Aversively-motivated associative learning allows animals to avoid harm and thus ensures survival. Aversive learning can be studied by the fear learning paradigm, in which an innocuous sensory stimulus like a tone (conditioned stimulus, CS), acquires a nega ...
