Lately, I (as someone with no experience or prior knowledge in the topic) have been thinking about...thinking. The part that intrigues me the most is memory. As a computer-y type person, I tend to think in logic and organized systems of bytes, but I understand this way of thinking about the brain is incorrect.
From what I can half-understand half-guess from the limited information I can find online, the brain is made up of neurons which build up memories in their interactions through synapses, which send chemicals to each other.
In order to visualize, say, a thumbtack, I would need a lot of information. I think trying to recall an image of a thumbtack would send a "trigger" to a neuron, telling it to pass it on to other neurons, building up an image from these chemicals. I think I've read these chemicals are also what causes emotions (dopamine especially being the one that comes to mind), but I could be mixing things up.
So when thinking about a thumbtack, those neurons would connect in a pattern, to ensure I get all the right signals to envision one. This makes a lot of a sense to me, and explains things like forgetting and the ability to imagine and visualize inexactly with ease, but not remember exact values or images.
Could anyone provide any insight into whether my somewhat informed guesses are correct, or to any more accurate explanations of what is currently known? Thanks!
