Welcome to the Mazzucato Lab

How do cognition and behavior emerge from the collective activity of large neuronal circuits in our brain? Can we simulate these neural circuits in silico to build artificial neural networks that explain brain function? Can we use our knowledge of circuit dynamics to build brain-machine interfaces to ameliorate cognitive abilities? Our lab leverages close collaborations with several experimental groups to address these questions, in particular:
  • Neural mechanisms underlying optimal performance and flexible behavior. What happens in your brain when you are "in the flow"? How does your internal arousal level affect cognitive function? 
  • Effects of psychedelic drugs and serotonin on neural dynamics and behavior. What is the neural mechanism underlying hallucinations and health benefits in the psychedelic state?
  • What are the rules of interactions between a brain and a computer?
  • What are the neural circuits enabling the awesome complexity of  naturalistic and social behavior?

Our lab addresses these questions blending methods from physics, machine learning, dynamical systems and network theory.

Our lab is part of the
International Network for Bio-Inspired Computing (IN-BIC), a research consortium funded by the NSF Accelnet program including nodes in the US, Canada, and France, whose goal is to identify and implement novel approaches to understanding cognitive function and biologically inspired artificial intelligence.


Our lab is passionate about creating an inclusive environment promoting diversity. We embrace a notion of intellectual community enhanced by diversity along a number of dimensions, including race, ethnicity and national origins, gender identity and presentation, disability, class and religion. We aim at fostering greater creativity and encouraging collaborative innovation and interactions.​
