Prof. Dr. med. Ruxandra Bachmann-Gagescu
Institute of Medical Genetics, University of Zurich Research Focus: Our research focuses on a group of human Mendelian disorders called ciliopathies which are unified by shared genetic causes resulting in primary cilium dysfunction. Primary cilia are small non-motile organelles present on the surface of most vertebrate cells where they are involved in transduction of sensory, mechanical or chemical signals and in regulation of signaling pathways during development and cell homeostasis. Typical clinical presentations of ciliopathies include neurological involvement, retinal degeneration and renal fibrocystic disease, as illustrated by Joubert syndrome (JS), an iconic ciliopathy which is the main focus of our research. To understand the consequences of mutations in JS-associated genes at the molecular level, we combine observations from human genetics studies on JS-patients with modelling in the zebrafish and in human iPSC-derived neurons using state-of-the-art techniques such as CRISPR/Cas9 genome editing or live imaging of transgenically-tagged ciliary proteins. Keywords: ciliopathies, primary cilia, Joubert syndrome, zebrafish, iPSC Topics: Development and Regeneration, Disorders of the nervous system Website: http://www.medgen.uzh.ch/en/forschung/gagescu.html

Prof. Dr. Daniel Brandeis Research Focus: We focus on mapping brain functions and plasticity in typical development, neurodevelopmental disorders, and treatment with electrical and multimodal imaging (EEG-fMRI, MRS, with S. Brem). Clinical projects cover longitudinal brain mapping in common neurodevelopmental disorders like Attention-Deficit/Hyperactivity Disorder (ADHD), aggression and Dyslexia. We characterize timing, localization and genetics (with E. Grünblatt) of compromised networks as endophenotypes as state dependent deficits during rest, attention, inhibition, reward processing, or print tuning etc. For clinical translation we focus on neurofeedback and biofeedback training (with R. Drechsler), and evaluate potential biomarkers using multimodal approaches. Keywords: ADHD, dyslexia, OCD, conduct disorder, development, plasticity, functional brain mapping, EEG, ERP, fMRI, MRS, neurofeedback, biofeedback, longitudinal studies, reading, attention, genetics, gene x environment interactions.

Prof. Dr. phil. Moritz M. Daum Research Focus: The overarching aim of the Research Group “Developmental Psychology” is to address the roots of infants’ and young children’s perception and understanding of their social world. The understanding of others as social agents is one of the most fundamental skills in our everyday social life. It is crucial for any engagement in cooperative and communicative activities. In our research, we are particularly interested in the mechanisms that form the bedrock of infants’ action perception, the interrelation of infants’ early action perception comprehension to the control of their own actions, the selective implementation of observed actions in one’s own actions. Current projects focus on the (neuro-)cognitive processes underlying infants’ and young children’s action understanding, the interrelation of action understanding and action performance across the whole lifespan, the interrelation of language and action in development, and the development of the self. Keywords: developmental psychology, infancy, life span, cognitive development, action perception language, imitation, eye tracking, EEG Topics: Development and Regeneration, Neural Basis of Behavior, Cognitive Neuroscience Publications: pubmed Website: http://www.psychologie.uzh.ch/fachrichtungen/devpsy/personen Lab: http://www.kleineweltentdecker.ch

Translational Molecular Psychiatry, University Clinic of Child and Adolescent Psychiatry, University of Zurich Research Focus: We are interested in finding risk factors and biomarkers for child and adolescent psychiatric disorders such as attention-deficit hyperactivity disorder (ADHD), early-onset obsessive-compulsive disorder (OCD), Autism spectrum disorders (ASD), psychosis and environmental /stress effects. In addition, the laboratory focuses on functional mechanisms of action of gene variants found to associate to a specific disorder as well as mechanism of action of drug therapies in various neuronal cellular models. Since psychiatric disorders are not only polygenetic predisposed but also influenced by environmental factors, epigenetic is another factor investigated in the lab. This could provide additional tools for early and differential diagnosis as well as therapy prediction.

Prof. Dr. Reto Huber Research Focus: Sleep wake regulatory mechanisms seem to be casually related to cortical plasticity. More specifically, wakefulness favours synaptic strengthening or synapse formation. On the other hand, sleep, in particular deep sleep, promotes synaptic weakening or synapse elimination, ensuring synaptic homeostasis. Cortical plasticity plays a key role for brain maturation. A large body of evidence indicates that aberrations in the trajectory of cortical plasticity are linked to the development of psychiatric disorders. We investigate mechanism underlying the interplay between sleep and wakefulness and how such mechanisms may impact the remodelling of cortical circuits during development and therefore might be related to the susceptibility of psychopathology.

Prof. Dr. Sebastian Jessberger Research Focus: New neurons are continuously generated in two discrete areas of the adult brain – the dentate gyrus of the hippocampus and the subventricular zone of the lateral ventricles. Our group is interested in the underlying biology of adult neurogenesis, including the fate plasticity of adult neural stem cells (NSCs) and the molecular mechanisms governing stem cell activity and neuronal integration. Currently, we use gene expression profiling together with analyses of the metabolic state of NSCs and their progeny to study the molecular framework of NSC diversity in the adult brain and to identify novel regulators of the neurogenic process. In addition, our laboratory aims to understand how physiologic and disease-associated alterations of the neurogenic niche are translated into stem cell-associated plastic changes of the adult brain on a cellular but also behavioral level.

Prof. Dr. Theofanis Karayannis Research Focus: The brain begins to form during embryogenesis, but undergoes a protracted period of development that lasts into adulthood. Our work is aimed at understanding how the environment moulds the construction and reconfiguration of neuronal circuits to allow them to effectively process and respond to external stimuli throughout development. The goal is to unravel how the interplay between electrical activity and genetic programs controls the assembly and plasticity of cortical circuits that are involved in processing and gating sensory information. To achieve this, we utilize a multi-dimensional approach that includes molecular, genetic and functional methods. It is our hope that this research will not only provide insights into the making of the healthy brain, but also into neurodevelopmental brain pathologies resulting from aberrant circuit wiring.

PD Dr. Marta Roccio Research Focus: Specialized sensory cells located into the inner ear translate with remarkable speed and accuracy sound-induced vibrations of different loudness and pitch into chemical signals that can be interpreted by the brain as sound. Loss or damage of these sensory cells results in permanent hearing loss as the human inner ear cannot repair after damage. The long-term goal of our research is to develop novel therapeutic strategies to counteract sensorineural hearing loss by uncovering fundamental biological principles that underlay development and disease. We are making use of in vitro models known as “inner ear organoids”, derived from directed differentiation of pluripotent stem cells (PSCs) to gain insight into inner ear sensory organ development and use them as unique tools to model disease. In addition we exploit cochlear organoids culture from inner ear progenitors to probe tissue regenerative potential. By leveraging recent advances in bioengineering, organoid culture and organ-on-chip technology, we aim to develop reproducible and robust in vitro models to study inner ear development, model disease and analyze drug-induced ototoxicity and otoregeneration. Methods: PSC derived inner ear organoid, cochlear progenitor culture, in vitro screening Keywords: Inner ear development, Hearing loss, Neuroscience, Disease Modeling Topics: Development and Regeneration, Sensory Systems Publications: https://www.scopus.com Website: http://www.orl.usz.ch/forschung/seiten/neurootologie.aspx
