About
Matthias N. Hartmann-Riemer is a clinical neuroscientist whose research focuses on the neurobiological underpinnings of negative symptoms in schizophrenia, particularly apathy and diminished expression. His major contributions lie in disentangling these symptom domains through behavioral paradigms, such as effort-based decision-making tasks. In his highly cited 2014 work, Hartmann-Riemer demonstrated that apathy—but not diminished expression—in schizophrenia is specifically linked to a reduced willingness to exert physical effort for monetary rewards, revealing a dissociation between motivational and expressive deficits. This finding has shaped how researchers conceptualize and measure negative symptoms, with the paper accumulating 8 citations and influencing subsequent translational studies. Hartmann-Riemer’s work bridges clinical psychiatry and cognitive neuroscience, employing computational modeling and neuroimaging to explore reward processing and effort allocation. His research has advanced understanding of the neural circuits underlying motivational impairments, offering potential targets for therapeutic interventions. By clarifying the behavioral and neural signatures of apathy, Hartmann-Riemer has provided critical insights that help refine diagnostic criteria and guide the development of personalized treatments for individuals with schizophrenia.
