The two are separated from each other by what is called a Markov blanket. to produce sensory information. This is the first crucial point in understanding the Bayesian brain hypothesis.
What is predictive coding in neuroscience?

Frequentists are people who define probabilities as representing long run frequencies. If you are only happy with one or other of these definitions then you are either a Bayesian or a frequentist.
Is the brain probabilistic?
There is strong behavioral and physiological evidence that the brain both represents probability distributions and performs probabilistic inference. Computational neuroscientists have started to shed light on how these probabilistic representations and computations might be implemented in neural circuits.

What is the main idea of psychoanalytic theory?
Psychoanalytic theory divides the psyche into three functions: the id—unconscious source of primitive sexual, dependency, and aggressive impulses; the superego—subconsciously interjects societal mores, setting standards to live by; and the ego—represents a sense of self and mediates between realities of the moment and …
