Reinforcement Learning and HTM Algorithm

These two posts are on data coding and the role of sleep, and the related transfer between the hippocampus and cortex.

How does short term memory work?

You did ask about LT/ST outside of the hippocampus and I did not answer your question directly but pointed you to the central nature of the entorhinal cortex / hippocampal formation (EC/HF) in the memory systems. I feel like I left your question less than half answered. There are several interrelated time scales in the memory system. The shortest is actual perception. Say what? Yes - perception is an active recall process. In the first part of perception, cells in the cortex and thalamus ha…

And this one that talks a little bit about the actual transfer:
… brain wave are known to excite the hippocampus in dreaming - driving a recall in both the cortex and hippocampus at the same time. If the hippocampus has leaned a response that makes it fire faster from new learning (using the “standard” spike timing learning ) this could trigger learning in the related cortex. This excitation sweeps through again and again as long as there are significant phase differences in response between the two areas."

On the necessity of sleep

To add a little more background on the nature of what is being encoded: I believe that everything that you learn is framed and parsed in terms of what you have learned before; you learn delta coding based on your prior life experiences. If you extend this all the way back you build on your innate built-in instinctive and emotional wiring as dictated by your genetics. It is nature first, then nurture. To flesh this out - as you experience the world prior memories are being recalled as part of y…
