Pertubative analysis methods for locus coeruleus and cortical coupling? Any work done on using things like EPR to study this?
I'd like to focus my future research on integrating this structure into major computational frameworks (Bayesian brain, predictive coding for instance). Something that seems pretty apparent when ...
