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

Eva Blondiaux

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 ...

Unraveling neural and behavioral mechanisms of cognitive self-attenuation and alienation

Giedre Stripeikyte

The present thesis aimed at investigating behavioral and neural underpinnings of the mechanisms related to the different aspects of self-monitoring. The first aim was to study functional connectivity alterations related to the mechanisms accounting for the ...

TMS-induced control of bodily self-consciousness by combining non-invasive brain stimulation and immersive virtual reality

Matteo Franza

Our brain constantly receives and integrates a flow of sensory and motor information that shapes the way our body is represented. Several experimental approaches have been proposed to alter the body representation, by manipulating exteroceptive or interoce ...

Sensorimotor Induction of Auditory Misattribution in Early Psychosis

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

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 ...

Processing pathways for emotional vocalizations

Stephanie Clarke, Sandra Elisabete Monney, Olivier Benoit Thomas Reynaud

Emotional sounds are processed within a large cortico-subcortical network, of which the auditory cortex, the voice area, and the amygdala are the core regions. Using 7T fMRI, we have compared the effect of emotional valence (positive, neutral, and negative ...

Gamma Knife radiosurgery for intravestibular and intracochlear schwannomas

Constantin Tuleasca

BackgroundSchwannomas of the VIIIth cranial nerve are benign tumours, with vast majority occurring in vestibular division. Rarely, they can also arise from distal branches of cochlear, superior or inferior vestibular. We review our experience with Gamma Kn ...

Sensorimotor Induction of Auditory Misattribution in Psychosis is Linked to Neural Disconnectivity

Olaf Blanke, Alessandra Griffa, Patric Hagmann, Andrea Serino, Roy Salomon, Giulio Rognini, Silvia Marchesotti

Background: Schneiderian first rank symptoms (FRS) are characterized by a diminished demarcation of self-other boundaries, causing misattribution of self-generated thoughts and actions to external sources. We have shown that introducing sensorimotor predic ...

Image Inpainting through Neural Networks Hallucinations

Pascal Frossard, Alhussein Fawzi

We consider in this paper the problem of image inpainting, where the objective is to reconstruct large continuous regions of missing or deteriorated parts of an image. Traditional inpainting algorithms are unfortunately not well adapted to handle such corr ...

Backward masking performance in patients with functional psychoses

Michael Herzog, Maya Roinishvili

In visual backward masking, a target is followed by a blank screen (ISI - Inter-stimulus-interval) and, then, a mask which deteriorates target processing. Schizophrenic patients show strong but complex processing deficits in visual masking compared to heal ...
