Imagination! ( a model )

Consider a model,

• A : there are signals received at the brain, from various (SNS) organs
• B: the brain has to interpolate all of this into some intermediate representation, which is somewhat different from the separate types of A. This is the sort of data we refer to as conscious memory.
• C : possibly there are other representations of the same data, stored elsewhere.

It is possible that we're only aware of A via B, never directly. Also C may feed into B. B loops within itself. Imagination!
