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

Michael Herzog, Maya Roinishvili, Ophélie Gladys Favrod, 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 ...

Cannabis use in early psychosis is associated with reduced glutamate levels in the prefrontal cortex

Rolf Gruetter, Lijing Xin, Kim Do

Recent studies have shown that cannabis may disrupt glutamate (Glu) signaling depressing Glu tone in frequent users. Current evidence have also consistently reported lower Glu-levels in various brain regions, particularly in the medial prefrontal cortex (m ...

Electrophysiological correlates of visual backward masking in first-episode psychosis

Michael Herzog, Maya Roinishvili, Ophélie Gladys Favrod

Schizophrenia is a heterogeneous disorder and among other symptoms, patients have important visual impairments. Visual paradigms are therefore important tools to investigate the mechanisms of schizophrenia. We have previously shown that visual backward mas ...

Apparent compensation mechanisms in relatives of schizophrenia patients in visual backward masking

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

Visual backward masking (VBM) is strongly deteriorated in schizophrenia patients. VBM is a potential endophenotype of schizophrenia reflecting the genetic underpinnings of the disease (Chkonia et al., 2010). Masking deficits are highly correlated with redu ...

Nano Secondary Ion Mass Spectrometry Imaging of Dopamine Distribution Across Nanometer Vesicles

Anders Meibom, Anna Larsson

We report an approach to spatially resolve the content across nanometer neuroendocrine vesicles in nerve-like cells by correlating super high-resolution mass spectrometry imaging, NanoSIMS, with transmission electron microscopy (TEM). Furthermore, intracel ...

Endophenotypes of schizophrenia: electrophysiological correlates of schizotypy

Michael Herzog, Christine Mohr, Ophélie Gladys Favrod, Guillaume Sierro

Endophenotypes are of crucial interest for schizophrenia research linking genetic abnormalities to pathology. During the last NCCR period, we have characterized one endophenotype, based on visual backward masking (VBM) deficits, behaviourally, electrophysi ...

Apathy and noradrenaline: silent partners to mild cognitive impairment in Parkinson's disease?

Kerstin Preuschoff, Leyla Loued-Khenissi

Purpose of review Mild cognitive impairment (MCI) is a comorbid factor in Parkinson's disease. The aim of this review is to examine the recent neuroimaging findings in the search for Parkinson's disease MCI (PD-MCI) biomarkers to gain insight on whether MC ...

Glutathione deficit impairs myelin maturation: relevance for white matter integrity in schizophrenia patients

Jean-Philippe Thiran, Rolf Gruetter, Lijing Xin, Alessandra Griffa, Aline Monin, Patric Hagmann, Kim Do, Philipp Baumann

Schizophrenia pathophysiology implies both abnormal redox control and dysconnectivity of the prefrontal cortex, partly related to oligodendrocyte and myelin impairments. As oligodendrocytes are highly vulnerable to altered redox state, we investigated the ...
