How cognition affects perception: Brain activity modelling to unravel top-down dynamics

  • Martin Desseilles (a1) (a2) (a3) and Christophe Phillips (a1)
Abstract

In this commentary on Firestone & Scholl's (F&S's) article, we argue that researchers should use brain-activity modelling to investigate top-down mechanisms. Using functional brain imaging and a specific cognitive paradigm, modelling the BOLD signal provided new insight into the dynamic causalities involved in the influence of cognitions on perceptions.
