How does buddhism describe what exactly, or where exactly, or how exactly, consciousness exists?

As a computer scientist interested in the origin of the universe and the mind, I finally have found some ancient stuff of the type of substance and depth I am looking for, the [Abhidhamma](http://www.abhidhamma.com/Vibhanga_Scan.pdf) . The first part of the Vibhanga (one of the sections of the Abhidhamma) talks about "aggregates" or "heaps" or "groups", [Skandha](https://en.wikipedia.org/wiki/Skandha) . This to me seems like it is near the foundation of what a computational model of consciousness would need to consider, as consciousness is one of the types of heaps or skandha. My question at this point in learning about this is, how exactly is consciousness structured in this model? _Where_ does consciousness exist exactly. As a human being, I _feel_ my body, but my conscious awareness feels like it is in the center of my brain, literally at a pin point. I can understand and model how a consciousness can use sensory organs to perceive information, but I don't understand how the consciousness itself can form. If everything is information in the end, or bundles of flowing information like these heaps/skandha, how does it aggregate and flow in a bundle in such a way to generate consciousness which you can feel? I can even go so far as to imagine something like a biological cell with its complicated machinery going so far as to gain control over its environment, so that as a machine it is so complex and highly functional that it acts like a conscious being. This isn't too hard to imagine. But what is hard to imagine is how the consciousness is _stored_, or _where it is_! How can I perceive and feel the perception is in the center of my brain? What does skandha and the Abhidhamma have to say about this, it's structure?
