predictive coding

"we use the predictive coding framework to formalize the idea of an entropic brain by combining notions proposed by Kwisthout & van Rooij (2015) regarding the importance of the amount of details or granularity of predictions, and Bastos et al.'s (2012) canonical microcircuits for predictive coding. We propose that the increased entropic state is created when top down predictions in affected brain areas break up and decompose into many more overly detailed predictions due to hyper activation of 5-HT2A receptors in layer V pyramidal neurons."
