Neural Correlates of Sequential Decision Making

In chess, a series of moves is made until a delayed sparse feedback (win, loss) is issued, which makes it impossible to evaluate the value of a single move. There are powerful reinforcement learning (RL) algorithms, which can cope with these sequential dec ...

Action Monitoring Cortical Activity Coupled to Submovements

José del Rocio Millán Ruiz, Michael Eric Anthony Pereira, Aleksander Sobolewski

Numerous studies have examined neural correlates of the human brain’s action-monitoring system during experimentally segmented tasks. However, it remains unknown how such a system operates during continuous motor output when no experimental time marker is ...

Visual backward masking and the schizophrenia spectrum: EEG correlates

Michael Herzog, Maya Roinishvili, Ophélie Gladys Favrod

Schizophrenia is a heterogeneous disease strongly influenced by genetic factors. We have previously shown that visual backward masking (VBM) is a very sensitive endophenotype of schizophrenia (Chkonia et al., 2010). Importantly, not only patients but also ...

Neural correlates of visual backward masking: Compensation mechanism in relatives of schizophrenia patients

Michael Herzog, Maya Roinishvili, Patricia Figueiredo, Janir Nuno Ramos Antunes Da Cruz

Visual backward masking (VBM) is a very sensitive endophenotype of schizophrenia. Masking deficits are highly correlated with reduced EEG amplitudes. In VBM, a target stimulus is followed by a mask, which decreases performance on the target. Here, we inves ...

Compensation of visual backward masking deficits in relatives of schizophrenia patients

Michael Herzog, Maya Roinishvili, Patricia Figueiredo, Janir Nuno Ramos Antunes Da Cruz

Visual backward masking (VBM) is a potential endophenotype of schizophrenia reflecting the genetic underpinnings of the disease (Chkonia et al., 2010). Masking deficits are highly correlated with reduced N1 amplitudes as shown by the Global Field Power (GF ...

Simultaneous EEG-fMRI at ultra-high field for the study of human brain function

João Pedro Forjaco Jorge

Scalp electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) have highly complementary domains, and their combination has been actively sought within neuroscience research. The important gains in fMRI sensitivity achieved with higher ...

Three-dimensional echo planar imaging with controlled aliasing: A sequence for high temporal resolution functional MRI

Rolf Gruetter, Wietske Van der Zwaag, José Pedro Rebelo Ferreira Marques, Daniel Gallichan, Mayur Narsude

Purpose In this work, we combine three-dimensional echo planar imaging (3D-EPI) with controlled aliasing to substantially increase temporal resolution in whole-brain functional MRI (fMRI) while minimizing geometry-factor (g-factor) losses. Theory and Metho ...

Increased intra-participant variability in schizophrenia: evidence from single-trial EEG analysis

Michael Herzog, Patricia Figueiredo, Janir Nuno Ramos Antunes Da Cruz

Visual deficits in schizophrenic patients are of particular interest because they reflect the deficient circuits of information processing in the brain. In our previous work, we showed that schizophrenic patients have decreased peak amplitudes and reduced ...

Targets but not flankers are suppressed in crowding as revealed by EEG frequency tagging

Michael Herzog, Vitaly Chicherov

Perception of a visual target can strongly deteriorate in the presence of flanking elements (crowding). For example, adding lines next to a vernier makes vernier offset discrimination difficult. Crowding is often considered a bottleneck of low-level vision ...
