Postdoctoral Researcher

e-mail: c.schreiweis(at)


I am a behavioral neurophysiologist, trained in a variety of behavioral paradigms, pharmacology, quantitative neuroanatomy, in vivo neuronal recording and neuromodulation (optogenetics, chemogenetics) in mouse models. After my PhD at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, and at the Massachusetts Institute of Technology, I came to Paris on a fellowship by the “Fondation pour la Recherche Medical”, where I joined the “Neurophysiology of Repetitive Behaviour” team in 2016. I am also a founding and active member of a neuroscientific initiative that engages for gender equity / equality.

my background

Since my childhood, I have been curious about how the human brain could acquire something as complex and beautiful as language. In order to explore this question, I accomplished both a masters in science (biology) and in the humanities (linguistics & literature), before merging it into an interdisciplinary PhD at the Max Planck Institute of Evolutionary Anthropology, Leipzig, Germany, in the Department of Evolutionary Genetics with Prs. Svante Pääbo & Wolfgang Enard. There, I behaviourally characterized a mouse model of human language evolution and found that this model automatized learned contents faster than control mice. Crucial for my findings were the years in Pr. Ann Graybiel’s lab at the Massachusetts Institute of Technology. Having obtained an FRM fellowship, I moved to Paris, where I studied the neuroanatomy of the same mouse model at the Institut du Fer à Moulin before joining the research group of Eric Burguière at the ICM in 2016.

current projects

My projects address learning and automatization in cortico-basal ganglia circuits in health and disease. While automatization might render us efficient in our daily lives and might enable us to acquire such complex systems as language and speech, a loss of cognitive control might lead to neuropsychiatric disorders such as obsessive-compulsive disorder (OCD) or Tourette Syndrome. Together with my colleagues, I study the neurobiological basis of aberrant repetitive behaviours such as compulsions or tics using mouse models, a project for which I obtained the 2016 L’Oréal-UNESCO fellowship. My other projects investigate the role of dopamine during automatization (international ANR project) as well as motivational aspects of cognitive control (BigBrainTheory, Daunizeau & Burguière).

extrascientific engagement

I am a founding and active member of the gender equality movement “XX Initiative” as well as a member of the gender equity committee at the Paris Brain Institute. Together with my colleagues, we have developed a neuroscientifically-based action plan in order to achieve gender equity / equality (Schreiweis et al., Nat Hum Behav, 2019). We alert and educate about gender inequity / inequality based on data and scientific publications in order to break implicit gender stereotypes hindering gender equity / equality, reaching scientists, scholastic structures as well as the greater public.
