High levels of childhood trauma associated with changes in hippocampal functional activity and connectivity in young adults during novelty salience

Childhood trauma (CT) has been linked to increased risk for psychosis. Moreover, CT has been linked to psychosis phenotypes such as impaired cognitive and sensory functions involved in the detection of novel sensory stimuli. Our objective was to investigat ...

Sparse non-negative super-resolution - simplified and stabilised

Armin Eftekhari, Hemant Tyagi

We consider the problem of non-negative super-resolution, which concerns reconstructing a non-negative signal x = Sigma(k )(i=1)a(i)delta(ti) from m samples of its convolution with a window function phi(s - t), of the form y(s(j)) = Sigma(k)(i=1) a(i) phi( ...

Psychometrics of Disembodiment and Its Differential Modulation by Visuomotor and Visuotactile Mismatches

Oliver Alan Kannape, Bigna Lenggenhager

Altered states of embodiment are fundamental to the scientific understanding of bodily self consciousness. The feeling of disembodiment during everyday activities is common to clinical conditions; however, the direct study of disembodiment in experimental ...

P300 in the park: feasibility of online data acquisition and integration in a Mobile Brain/Body Imaging setting

Silvestro Micera, Fiorenzo Artoni, Elena Galeasso

In the last years Mobile Brain/Body Imaging (MoBI) has been increasingly used to study cognition in the real world to give more ecological validity to brain imaging studies currently carried out only inside the lab. To increase portability of the setup and ...

An intracerebral exploration of functional connectivity during word production

Amandine Grappe

Language is mediated by pathways connecting distant brain regions that have diverse functional roles. For word production, the network includes a ventral pathway, connecting temporal and inferior frontal regions, and a dorsal pathway, connecting parietal a ...

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, Lukas Heydrich, Bruno Herbelin, Jane Aspell

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 ...

mano: A Wearable Hand Exoskeleton for Activities of Daily Living and Neurorehabilitation

José del Rocio Millán Ruiz, Luca Randazzo, Inaki Asier Iturrate Gil, Serafeim Perdikis

Hand sensorimotor impairments are among the most common consequences of injuries affecting the central and peripheral nervous systems, leading to a drastic reduction in the quality of life for affected individuals. Combining wearable robotic exoskeletons a ...

Visual masking and schizophrenia: enhancement deficit 200 ms after stimulus onset

Michael Herzog, Ophélie Gladys Favrod, Maya Roinishvili, Janir Nuno Ramos Antunes Da Cruz

Masking is strongly deteriorated in schizophrenia patients and to a lesser extent in their healthy relatives. For this reason, masking is a good endophenotype. Here, we show the EEG correlates of masking across the schizophrenia continuum in order to tackl ...

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 ...

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, Janir Nuno Ramos Antunes Da Cruz, Albulena Jashari-Shaqiri

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 ...

Spatiotemporal Dynamics of the Cortical Responses Induced by a Prolonged Tactile Stimulation of the Human Fingertips

Silvestro Micera, Fiorenzo Artoni

The sense of touch is fundamental for daily behavior. The aim of this work is to understand the neural network responsible for touch processing during a prolonged tactile stimulation, delivered by means of a mechatronic platform by passively sliding a ridg ...

Visual backward masking in siblings of schizophrenia patients: evidence for a compensation mechanism

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

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 ...

The electrophysiological effects of the serotonin 1A receptor agonist buspirone in emotional face processing

Fosco Bernasconi

Emotional face processing is critically modulated by the serotonergic system, and serotonin (5-HT) receptor agonists impair emotional face processing. However, the specific contribution of the 5-HT1A receptor remains poorly understood. Here we investigated ...
