Neuroscience Seminar Series: Christoph Kellendonk Ph.D "Using human brain imaging studies as a guide towards animal models for schizophrenia"

The Kellendonk laboratory uses mouse genetic tools in an effort to understand the biology that underlies cognitive and negative symptoms of schizophrenia. Schizophrenia is characterized by three symptom clusters: the cognitive, negative and positive symptoms. While the positive symptoms – which include disordered thought processes, hallucinations and delusions – are the most characteristic feature of the disorder, such symptoms are more difficult to model in the mouse. In contrast, cognitive and negative symptoms of the disorder – including deficits in working memory and motivation – have behavioral readouts in mice that are more homologous to humans. Cognitive and negative symptoms are poorly understood, difficult to treat and their severities are a better predictor for the long-term prognosis of patients than the degree of positive symptoms.
