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

José del Rocio Millán Ruiz, Robert Leeb, Luca Tonin, 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 ...

Relevance of a complete road surface description in vehicle–bridge interaction dynamics

Pablo Antolin Sanchez

A fully coupled method for reproducing road vehicle-bridge dynamic interaction is presented in which finite element models are used for the structure, multibody dynamics models for the vehicles and interaction is represented by means of a contact with the ...

Time-Dependent Approach for Single Trial Classification of Covert Visuospatial Attention

José del Rocio Millán Ruiz, Robert Leeb, Luca Tonin

Recently, several studies have started to explore covert visuospatial attention as a control signal for brain–computer interfaces (BCIs). Covert visuospatial attention represents the ability to change the focus of attention from one point in the space with ...

Spatial neglect and perseveration in visuomotor exploration

Roberta Ronchi, Giuseppe Vallar

OBJECTIVE: Right-brain-damaged patients with left spatial neglect make perseveration errors in target cancellation tasks. A recent study (Ronchi, Posteraro, Fortis, Bricolo, & Vallar, 2009) showed that perseveration occurred more frequently in star than in ...

Using Goal- and Grip-Related Information for Understanding the Correctness of Other's Actions: An ERP Study

Michiel van Elk

Detecting errors in other's actions is of pivotal importance for joint action, competitive behavior and observational learning. Although many studies have focused on the neural mechanisms involved in detecting low-level errors, relatively little is known a ...

Event-related potentials and changes of brain rhythm oscillations during working memory activation in patients with first-episode psychosis

Jonas Richiardi

Background: Earlier contributions have documented significant changes in sensory, attention-related endogenous event-related potential (ERP) components and theta band oscillatory responses during working memory activation in patients with schizophrenia. In ...

Hyperconnectivity and Slow Synapses during Early Development of Medial Prefrontal Cortex in a Mouse Model for Mental Retardation and Autism

Michele Giugliano

Neuronal theories of neurodevelopmental disorders (NDDs) of autism and mental retardation propose that abnormal connectivity underlies deficits in attentional processing. We tested this theory by studying unitary synaptic connections between layer 5 pyrami ...

Auditory perceptual decision-making based on semantic categorization of environmental sounds

Fosco Bernasconi, Athina Tzovara

Discriminating complex sounds relies on multiple stages of differential brain activity. The specific roles of these stages and their links to perception were the focus of the present study. We presented 250 ms duration sounds of living and man-made objects ...

Recovery of the default mode network after demanding neurofeedback training occurs in spatio-temporally segregated subnetworks

Dimitri Nestor Alice Van De Ville, Rotem Roza Kopel

The default mode (DM) network is a major large-scale cerebral network that can be identified with functional magnetic resonance imaging (fMRI) during resting state. Most studies consider functional connectivity networks as stationary phenomena. Consequentl ...

Sweet sixteen for ANLS

Pierre Magistretti, Luc Pellerin

Since its introduction 16 years ago, the astrocyte-neuron lactate shuttle (ANLS) model has profoundly modified our understanding of neuroenergetics by bringing a cellular and molecular resolution. Praised or disputed, the concept has never ceased to attrac ...
