Hallucination Engineering: From Neuroscience Robotics to Hallucinations in Health and Disease

My thesis focuses on a psychotic symptom called the presence hallucination (PH). PHs are defined as the false perception that someone is nearby when no one is actually present. PHs can occur in various populations, ranging from healthy subjects (when expos ...

Sensorimotor Induction of Auditory Misattribution in Early Psychosis

Olaf Blanke, Andrea Serino, Alessandra Griffa, Fosco Bernasconi, Patric Hagmann, Kim Do, Roy Salomon, Giulio Rognini, Silvia Marchesotti, Pierre Progin

Dysfunction of sensorimotor predictive processing is thought to underlie abnormalities in self-monitoring producing passivity symptoms in psychosis. Experimentally induced sensorimotor conflict can produce a failure in bodily self-monitoring (presence hall ...

EEG microstates and the schizophrenia spectrum: evidence for compensation mechanisms

Michael Herzog, Christine Mohr, Maya Roinishvili, Ophélie Gladys Favrod, Patricia Figueiredo

Introduction: Electroencephalogram (EEG) microstates are on-going scalp potential configurations that remain stable for around 80 ms (1). Four recurrent and dominant classes of microstates (labeled A-D) are observed in resting-state EEG, explaining around ...

Visual masking in Schizophrenia: an endophenotype and its neural correlates

Michael Herzog, Maya Roinishvili, Ophélie Gladys Favrod

Objective: In visual backward masking, a target is followed by a mask, which deteriorates performance on the target. Masking is a very sensitive endophenotype for schizophrenia. Patients and their siblings (to a lesser extent) show strong performance defic ...

EEG signatures of schizophrenia: visual backward masking and microstates

Janir Nuno Ramos Antunes Da Cruz

Schizophrenia is a complex and devastating mental disorder that influences how one behaves, feels, and thinks. It affects a little less than 1 % of the world population and it is understood to be partly genetically mediated. Several genetic risk factors of ...

An energetic view of stress: Focus on mitochondria

Maria del Carmen Sandi Perez

Energy is required to sustain life and enable stress adaptation. At the cellular level, energy is largely derived from mitochondria – unique multifunctional organelles with their own genome. Four main elements connect mitochondria to stress: 1) Energy is r ...

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 ...

Stress, glucocorticoid receptor and social behaviors

Peripuberty, comprising childhood and adolescence, constitutes an important time window in the brain development and maturation. Exposure to prolonged stress during this period has been shown to increase the risk for the development of psychopathologies la ...

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 ...

The Subjective Sensation of Synchrony: An Experimental Study

Pierre Magistretti, Delphine Preissmann, Joan Llobera Mahy

People performing actions together have a natural tendency to synchronize their behavior. Consistently, people doing a task together build internal representations not only of their actions and goals, but also of the other people performing the task. Howev ...
