Modular organization of reaching and grasping movements investigated using EEG microstates

Dimitri Nestor Alice Van De Ville, Robert Leeb, Elvira Pirondini, Silvestro Micera, Martina Coscia, Jesús Minguillón Campos

How movements are generated and controlled by the central nervous system (CNS) is still not well understood. In this work, we tested the hypothesis of a modular organization of the brain activity during the execution of voluntary movements. In particular, ...

Clinical evaluation of BrainTree, a motor imagery hybrid BCI speller

José del Rocio Millán Ruiz, Michele Tavella, Serafeim Perdikis, Robert Leeb

Objective. While brain-computer interfaces (BCIs) for communication have reached considerable technical maturity, there is still a great need for state-of-the-art evaluation by end-users outside laboratory environments. To achieve this primary objective, i ...

Subject-oriented training for motor imagery brain-computer interfaces

José del Rocio Millán Ruiz, Serafeim Perdikis, Robert Leeb

Successful operation of motor imagery (MI)-based brain-computer interfaces (BCI) requires mutual adaptation between the human subject and the BCI. Traditional training methods, as well as more recent ones based on co-adaptation, have mainly focused on the ...

Transferring BCI skills to successful application controls

José del Rocio Millán Ruiz, Alberto Molina Arribere, Luca Tonin, Serafeim Perdikis, Robert Leeb, Andrea Biasiucci, Marco Creatura, Tom Edward Carlson

The goal of our research is to enable various end-users to control applications by using a brain-computer interface (BCI). Since applications–like telepresence robots, wheelchairs or text entry systems–are quite demanding a good level of BCI control is nee ...

Transferring brain-computer interfaces beyond the laboratory: Successful application control for motor-disabled users

José del Rocio Millán Ruiz, Alberto Molina Arribere, Luca Tonin, Michele Tavella, Serafeim Perdikis, Robert Leeb, Andrea Biasiucci, Marco Creatura, Tom Edward Carlson

OBJECTIVES: Brain-computer interfaces (BCIs) are no longer only used by healthy participants under controlled conditions in laboratory environments, but also by patients and end-users, controlling applications in their homes or clinics, without the BCI exp ...

An online EEG BCI based on covert visuospatial attention in absence of exogenous stimulation

José del Rocio Millán Ruiz, Luca Tonin, Robert Leeb, Aleksander Sobolewski

Objective. In this work we present—for the first time—the online operation of an electroencephalogram (EEG) brain–computer interface (BCI) system based on covert visuospatial attention (CVSA), without relying on any evoked responses. Electrophysiological c ...

Selective Enhancement of Motor Imagery Features Using Transcranial Direct Current Stimulation

Ricardo Andres Chavarriaga Lozano, José del Rocio Millán Ruiz, Robert Leeb, Andrea Biasiucci

Transcranial Direct Current Stimulation (tDCS) has been shown to selectively modulate cortical responses in memory, motor and perceptual tasks. Here we show that this type of stimulation results in targeted enhancement of brain patterns elicited during mot ...

The hybrid Brain-Computer Interface: a bridge to assistive technology?

José del Rocio Millán Ruiz, Robert Leeb

Brain-Computer Interfaces (BCIs) can be extended by other input signals to form a so-called hybrid BCI (hBCI). Such an hBCI allows the processing of several input signals with at least one brain signal for control purposes, i.e. communication and environme ...

Feel the BCI vibe – vibrotactile BCI feedback

José del Rocio Millán Ruiz, Robert Leeb

Controlling a device via a brain-computer interface (BCI) requires the participant to look and to split the attention between the device and the BCI feedback, which is partly contradictory. Therefore, a stimulation system based on 6 coin-motors is develope ...

Thinking Penguin: Multi-modal Brain-Computer Interface Control of a VR Game

Robert Leeb

We describe a multi-modal brain-computer interface (BCI) experiment, situated in a highly immersive CAVE. A subject sitting in the virtual environment controls the main character of a virtual reality game: a penguin that slides down a snowy mountain slope. ...

Motor Recovery After Stroke by Means of BCI-Guided Functional Electrical Stimulation

José del Rocio Millán Ruiz, Robert Leeb, Andrea Biasiucci

Brain-Computer Interfaces (BCIs) provide a mean to access the damaged motor network of the brain after stroke, and could be used to drive and promote beneficial plasticity. Among the available therapeutic approaches, Functional Electrical Stimulation (FES) ...

Brain-Actuated Assistive Mobility For Disabled End-User

José del Rocio Millán Ruiz, Luca Tonin, Robert Leeb, Tom Edward Carlson

Brain-Computer Interfaces (BCIs) have been successfully used to control assistive mobility devices (like a telepresence robot or an electric wheelchair) using only motor imagery. Importantly, disabled end-users are able to achieve similar performances as h ...

Brain-Machine Interfaces: Progress in Large Clinical Validation

José del Rocio Millán Ruiz, Luca Tonin, Serafeim Perdikis, Robert Leeb, Andrea Biasiucci, Tom Edward Carlson

Brain-machine interfaces (BMI) have largely been demonstrated in laboratory conditions involving, mainly, healthy users. We have recently carried out a series of studies with a substantial number of motor-disabled end-users operating different brain-contro ...

A Hybrid BCI for Enhanced Control of a Telepresence Robot

José del Rocio Millán Ruiz, Luca Tonin, Serafeim Perdikis, Robert Leeb, Tom Edward Carlson

Motor-disabled end users have successfully driven a telepresence robot in a complex environment using a Brain-Computer Interface (BCI). However, to facilitate the interaction aspect that underpins the notion of telepresence, users must be able to voluntari ...

Freeing the visual channel by exploiting vibrotactile BCI feedback

José del Rocio Millán Ruiz, Robert Leeb

Controlling a brain-actuated device requires the participant to look at and to split his attention between the interaction of the device with its environment and the status information of the Brain-Computer Interface (BCI). Such parallel visual tasks are p ...
