The CoCoSys lab is based at Leiden University in The Netherlands, and led by Dr. Anne E. Urai.
In our neuroscience work, we investigate how the brain transforms sensory information into useful decisions, and how variability in such decisions change over multiple timescales, including ageing. Our research combines psychophysics and computational modeling of behavioral data with neurophysiological recordings in humans and rodents.
A new line of research investigates processes of social change, and especially social tipping points, for sustainability in climate action.
We are also passionate advocates for team science, open science and reproducibility, diversity and equality in academia (and beyond), and sustainable academic practices in face of the climate crisis.
