Neural correlates of target enhancement

Michael Herzog, Ophélie Gladys Favrod, Patricia Figueiredo, Janir Nuno Ramos Antunes Da Cruz, Phillip Ready Johnston

When a task-relevant stimulus is presented for a brief duration or with low contrast, neural enhancement is needed to boost the weak responses to the target. Otherwise, the stimulus goes unnoticed, which is the default when the stimulus is task-irrelevant. ...

Time course of prediction errors in sequential decision making

Michael Herzog, He Xu

In reinforcement learning, an agent makes sequential decisions to maximize reward. During learning, the actual and expected outcome are compared to tell whether a decision was good or bad. The difference between the actual outcome and expected outcome is t ...

Cardio-visual full body illusion alters bodily self-consciousness and tactile processing in somatosensory cortex

Olaf Blanke, Bruno Herbelin, Jane Aspell, Lukas Heydrich

Prominent theories highlight the importance of bodily perception for self-consciousness, but it is currently not known whether this is based on interoceptive or exteroceptive signals or on integrated signals from these anatomically distinct systems, nor wh ...

Neural Correlates of Sequential Decision Making

Michael Herzog, He Xu

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 ...

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 ...

Interoceptive signals impact visual processing: Cardiac modulation of visual body perception

Olaf Blanke, Fosco Bernasconi, Roberta Ronchi, Christian Pfeiffer, Mariia Kaliuzhna, Javier Bello Ruiz

Multisensory perception research has largely focused on exteroceptive signals, but recent evidence has revealed the integration of exteroceptive signals with interoceptive information. Such research revealed that heartbeat signals affect sensory (e.g., vis ...

Locating Temporal Functional Dynamics of Visual Short-Term Memory Binding using Graph Modular Dirichlet Energy

Pierre Vandergheynst, Benjamin Ricaud, Nauman Shahid, Keith Malcom Smith

Visual short-term memory binding tasks are a promising early marker for Alzheimer's disease (AD). To uncover functional deficits of AD in these tasks it is meaningful to first study unimpaired brain function. Electroencephalogram recordings were obtained f ...

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 ...

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 ...
