How does perception exit neural activity to observe a brain and conceive of neural activity? — Constance
Through self reflection. The brain has the ability to focus on, conjure up, root around in its storage (memories) for large swathes of beliefs, concepts, sensations and ideas that it holds, in essence compartmentalise some of itself, review that info, make new associations (novel perspectives/insights) and in doing so condense that into some more refined conclusions.
The whole brain cannot self reflect on the whole brain as there is no neural networks available to make computations while the others remain static and observed. It can only compartmentalise portions of itself but I suspect these portions can be quite large. Mathematically it doesn't take many neurons to exponentially increase their computational ability. Like factorials in maths.
10 factorial (all the possible arrangements/connections between just 10 neurons) is around 3,628,000 anatomical arrangements. And that's assuming they can just make one connection with one other neuron that isn't already connected to another in the set at a time! When in reality they can connect many branches/synapses with one another - up to 15,000 - dozens of which can be just between two neighbouring neurons.
The "focus of attention" is just that - a focus/focal point, that part of your conscious awareness that can meander through the matrix of collected information and compare it with other stuff. What we aren't actively focusing on at any given time is the subconscious - all those things you "didn't realise you knew" until prompted by a specific trigger or cue that directs you to the memory in question. Like nostalgia for example when you smell something that suddenly reminds you of your grandmother's cooking as a child.
Not only can neural networks process themselves in this way (self reflect). But they can also look outwards to learn about/ secure its own identity by associating with what's around it. Knowing the self by knowing what it isn't (the external world). Observation of exterior incoming data (the external world) is just as important as the reviewing and modulation of internal data (the mind/internal world).
Because in discerning similarities and differences between us and other things (people, animals, beliefs, cultures, customs, classifications: living, dead, animal, plant etc) we are gathering information and making associations between them within our mind (our own neural network).
When we can relate with another for example - by referencing their trauma to a similar trauma that we have already stored away, or if their behaviour and opinions towards the trauma are in line with what we would expect them to say, because its what we ourselves would say, then that's empathy. That is how empathy as a concept can be associated with neural processes - comparison of data and rejection/acceptance of the "likeness" of their data with ours.
We naturally tend to empathise more with loved ones and friends because they are similar to us. We have experienced eachother and enjoy that experience and feel connected to them. They are relatable. It's much harder to empathise with things we have never experienced - strangers, and unfamiliar/strange situations and events that we can't approach with the memories and experiences we have available to us to compare.
