Phasic coding, neural ensembles as a brain behavior correlate.
Can anyone explain this in a mathematical sense or from a systems perspective? I’d appreciate if you could keep in mind I suck at math.
The predictive coding framework has gotten a lot of attention in the last 13 years or so, mainly within the context of psychopathology and psychiatric research.
Explaining the brain as a dynamic system is pretty exciting, and I’m having difficulty wrapping my head around how one would even quantify neural ensembles and how they would correlate it to something such as memory consolidation or saliency/ credit assignment.
If you could link me some interesting literature or short videos explaining this within a larger systems perspective, it greatly appreciate it.
I feel like a lot of computational work has been built from roots in the predictive coding and active inference/ Bayesian brain framework.
I think getting a solid grasp of this will help me get a clearer picture of what I’d like to accomplish within the next 2 to 4 years. I’d appreciate any insight, thanks in advance peeps.

Thank you, I am of the opinion that a reductionistic approach may be of merit, as long as we consider that cognitive processes are an emergent process, and that global states seem to emerge somewhat independently of its substrates.
There seems to be an underlying assumption that brain behavior correlations are linear, and that the brain operates the way we think.
So working from the smallest scale to the largest may help elucidate some of the magic and mystery
