Abstract

Predictive coding and neural oscillations are two descriptive levels of brain functioning whose overlap is not yet understood. Chao et al. (2018) now show that hierarchical predictive coding is instantiated by asymmetric information channeling in the γ and α/β oscillatory ranges.

Keywords: beta; gamma; hierarchical depth; oscillations; predictive coding.
