Information Processing Biases: The Effects of Negative Emotional Symptoms on Sampling Pleasant and Unpleasant Information

Although theories of emotion associate negative emotional symptoms with cognitive biases in information processing, they rarely specify the details. Here, we characterize cognitive biases in information processing of pleasant and unpleasant information, an ...

Sex Differences in Comorbidity Combinations in the Swedish Population

Patrick Karl Alois Neff

High comorbidity rates, especially mental-physical comorbidity, constitute an increasing health care burden, with women and men being differentially affected. To gain an overview of comorbidity rates stratified by sex across a range of different conditions ...

The diagnostic potential of multimodal neuroimaging measures in Parkinson's disease and atypical parkinsonism

Chang-Hyun Park

Introduction For the diagnosis of Parkinson's disease (PD) and atypical parkinsonism (AP) using neuroimaging, structural measures have been largely employed since structural abnormalities are most noticeable in the diseases. Functional abnormalities have b ...

Electrophysiological correlates of visual backward masking in the schizophrenia continuum

Ophélie Gladys Favrod

In visual backward masking (VBM), a target is followed by a mask. Over the past decade, a VBM task, called the Shine-Through paradigm (ST), has been shown to be a very sensitive endophenotype of schizophrenia. In the present thesis, the electrophysiologica ...

Resting-State Networks of Adolescents Experiencing Depersonalization-Like Illusions: Cross-sectional and Longitudinal Findings

Dimitri Nestor Alice Van De Ville, François Lazeyras

The mirror-gazing task (MGT) experimentally induces illusions, ranging from simple color changes in the specular image of oneself, to depersonalization-like anomalous self-experiences (ASE) as in experiencing one's specular image as someone else. The objec ...

Visual masking deficits in schizophrenia: A view into the genetics of the disease through an endophenotype

Michael Herzog, Jacques Fellay, Maya Roinishvili, Flavia Aurelia Shoko Hodel

Schizophrenia is a chronic disorder determined by a complex mix of genetic and environmental factors. To better understand the contributions of human genetic variation to schizophrenia, we performed a genome-wide association study of a validated endophenot ...

The complexity of schizophrenia: a battery of tests

Michael Herzog

Schizophrenia research has focused on single mechanisms mainly. Classically, a paradigm is chosen, such as a cognitive or perceptual test. The outcome is usually that schizophrenia patients perform worse than controls. Substantial research is then spent to ...

Neuroligin-2 expression in the prefrontal cortex is involved in attention deficits induced by peripubertal stress

Maria del Carmen Sandi Perez, Stamatina Tzanoulinou, Jocelin Grosse, Olivia Zanoletti, Orbicia Riccio Wicht

Emerging evidence indicates that attention deficits, which are frequently observed as core symptoms of neuropsychiatric disorders, may be elicited by early life stress. However, the mechanisms mediating these stress effects remain unknown. The prefrontal c ...

Does chronic nicotine consumption influence visual backward masking in schizophrenia and schizotypy?

Michael Herzog, Christine Mohr, Albulena Jashari-Shaqiri, Maya Roinishvili, Guillaume Sierro

Nicotine consumption is higher for people within the schizophrenia spectrum compared to controls. This observation supports the self-medication hypothesis, that nicotine relives symptoms in, for example, schizophrenia patients. We tested whether performanc ...
