Attention-Related Potentials Allow for a Highly Accurate Discrimination of Mild Cognitive Impairment Subtypes

The three most frequent forms of mild cognitive impairment (MCI) are single-domain amnestic MCI (sd-aMCI), single-domain dysexecutive MCI (sd-dMCI) and multiple-domain amnestic MCI (md-aMCI). Brain imaging differences among single domain subgroups of MCI w ...

Eeg Anomalies In Adult Adhd Subjects Performing A Working Memory Task

Functional imaging studies have revealed differential brain activation patterns in attention deficit hyperactivity disorder (ADHD) adult patients performing working memory (WM) tasks. The existence of alterations in WM-related cortical circuits during chil ...

Detection of Anticipatory Brain Potentials during Car Driving

José del Rocio Millán Ruiz, Ricardo Andres Chavarriaga Lozano, Lucian Andrei Gheorghe, Zahra Khaliliardali

Recognition of driver’s intention from electroencephalogram (EEG) can be helpful in developing an in-car brain computer interface (BCI) systems for intelligent cars. This could be beneficial in enhancing the quality of interaction between the driver and th ...

Anticipation- and Error-related EEG Signals during Realistic Human-Machine interaction: A Study on Visual and Tactile Feedback

José del Rocio Millán Ruiz, Roland Siegwart, Ricardo Andres Chavarriaga Lozano, Xavier Perrin

The exploitation of EEG signatures of cognitive processes can provide valuable information to improve interaction with brain actuated devices. In this work we study these correlates in a realistic situation simulated in a virtual reality environment. We fo ...

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 ...

A 7 tesla FMRI study of amygdala responses to fearful faces

Wietske Van der Zwaag, Nouchine Hadjikhani, Nicole Regula Zürcher Wimmer

The amygdalae are involved in the perception of emotions such as happiness, anger and fear. Because of their proximity to the sinuses, the image signal intensity in T2* weighted fMRI data is often affected by signal loss due to through-slice dephasing, esp ...

Single Trial Recognition of Anticipatory Slow Cortical Potentials: The Role of Spatio-Spectral Filtering

José del Rocio Millán Ruiz, Ricardo Andres Chavarriaga Lozano, Gangadhar Garipelli

Single trial recognition of slow cortical potentials (SCPs) from full-band EEG (FbEEG) faces different challenges to classical EEG such as noisy, high magnitude (~±100µV) infra slow oscillations (ISO) with f

Cortical Current Density vs. Surface EEG for Event-Related Potential-based Brain-Computer Interface

José del Rocio Millán Ruiz, Ricardo Andres Chavarriaga Lozano, Mohit Kumar Goel

In this paper we use the cortical current density based inverse solution to classify Event Related Potential, in particular for error-related potential elicited during Brain-Computer Interface experiment. We selected discriminant cortical sources for compa ...

EEG Single-Trial Classification of Visual, Auditive and Vibratory Feedback Potentials in Brain-Computer Interfaces

Inaki Asier Iturrate Gil, Marco Creatura

Feedback stimuli are fundamental components in Brain-Computer Interfaces. It is known that the presentation of feedback stimuli elicits certain brain potentials that can be measured and classified. As stimuli can be given through different sensory modaliti ...

An Analysis of Language Mismatch in HMM State Mapping-Based Cross-Lingual Speaker Adaptation

John David Scott Dines, Hui Liang

This paper provides an in-depth analysis of the impacts of language mismatch on the performance of cross-lingual speaker adaptation. Our work confirms the influence of language mismatch between average voice distributions for synthesis and for transform es ...
