Hi all,
Since earlier this year when I was first introduced to HTM, I have spent a lot of time day to day gradually comprehending how it can help explain different aspects of thought and intelligence.
I have a list of these aspects that I’m still not sure about, in other words I don’t have an HTM-oriented explanation or analogy.
Instead of dumping them all in one topic, I’ll ask them one at a time and see if the HTM community can help by:
a) directing me to some good reading
b) offering your own ideas or explanation
c) telling me that nobody knows the answer yet
This first question relates to how “background” thoughts work in the neocortex. By this I mean that the thought doesn’t feel as though it occupies my attention, but there is either some level of effort being invested into it, or it is idle but will spontaneously re-enter my attention over the coming minutes, hours or sometimes days.
Examples:
- Someone proposes a question to me of a memory recall nature (“what was the name of the main actor in movie X”, or “which band sang song Y”). I can’t recall it, but then a few hours later it spontaneously pops into my head.
- Someone proposes a question to me of a technical nature (“what is the best approach to solving problem X”), and I’ll tell them I need to think about it and come back to them. But without really spending much time consciously pondering it, the next day I am usually feel much better placed to propose a solution.
- I tell myself I need to remember to get milk before going home, or similarly I tell myself that I have to remember to talk to a certain person about a certain topic. Later on, often hours later, I spontaneously remember to do it (hopefully, anyway…it doesn’t always happen).
With HTM, neurons are activated up and down the layers of columns, with the representations becoming more invariant further up the hierarchy. But to borrow a Comp Sci term, are there many “threads” of neuron activation? And if so:
- How many could there be at any one time?
- Is there a “main” one, or what is it that would make one of them feel “active” in our attention?
- How do they interact or interrupt each other?
- Would they all generally involve the full hierarchy? It doesn’t seem to make sense that the lower levels would be involved in these sorts of tasks, so does that mean the activations become predominately Distal for some period until a downward path is available?
I have a feeling that perhaps I’m making a too simplistic connection between the basic HTM theory and the topic of attention.
