Different paths of information routing preserve scale-free neuronal and behavioural dynamics. Psychedelics promote altered mental states and under certain conditions, mental health. Recent investigation into the mechanism of psychedelics has focused on whole-brain models. We study the relationship between functional connectivity (FC) and neuronal and behavioral dynamics on the microscale in the retro-splenial cortex (RSC) of mice, under the psychoactive drug ibogaine. We found that the functional network is re-arranged (information re-routing) while neuronal and behavioral dynamics are unchanged.
