Controlled sampling of non-equilibrium brain dynamics: modeling and estimation from neuroimaging signals
Matthieu Gilson · Bernstein Conference 2024
The spatio-temporal structure of brain dynamics at the macroscopic level has been hypothesized to reflect neuronal communication for cognitive processes. In particular, recent studies have focused on time-irreversibility and its relationship with consciousness [1,2]. Beyond this example of high-level cognitive function, this raises the question of the role of different ingredients that shape the structure-function relationship in whole-brain dynamics, which can be formalized using the Ornstein-Uhlenbeck (OU) process that combines input “noise” and effective connectivity as key ingredients.
