(This is the pattern completion mentioned above) These traces decay rapidly, depending on the number of maps and subcortical structures that form your current conscious perception of “now;” a few seconds to a few minutes. The circulation from highest level of the hierarchy (temporal lobe), through subcortex, out to the forbrain, and projections from the forbrain back to the sensor hierarchy form the basic loop of consciousness.

Much of what the brain does has no cortical representation and as such, is not available to introspection. Just for fun, try to bring saccades into your consciousness. The scanning and integration of objects is an observed behavior but try as I like, I can’t “experience” it. Likewise, the loop of consciousness has a significant portion of the process in subcortical structures. We can draw a box about the “subconscious” but it is not available to in… > [@Thought Experiment / Consciousness & Awareness](https://discourse.numenta.org/t/thought-experiment-consciousness-awareness/5655/36): > > What it feels like (contents) is the physical act of short term memory (the here-and-now part) of the perception part where you are recalling the best match up bits of your prior experience to the current perception. And the novel bits that don’t match but that you are learning online. This is felt in the episodic portion of the temporal lobe. When I localized this I am putting what is perhaps undue emphasis on this part as the entire brain is engaged in this perception and there numerous mecha… > [@Does HTM have an explanation for chunking, magnification, and remapping in the cortex?

It is an emergent property of system level operation. The current “contents of consciousness” - the collection of interlocking maps in the brain, each holding some part of the parsed here and now; a basket of interlocking features that combine to describe some unique collection that we take as a chunk.
