how is the brain able to give us images when we are imagining something?
In: Biology
Probably how it can sense pain from an amputated limb. What actually matters for us to feel something is the representation of various experiences like pain, excitement, in our cortex. And stimulating those very areas tends to do the same job of excitement or pain. Similarly, areas related to memory and learning when excited, emulate a visual experience. For imagining new things, probably all the experience in the memory is used to form a certain scenario. There’s a limitation, for example, you can’t imagine being in the deep sea. If you do, it won’t be accurate and would be something you just fed yourself as reality. So our brain uses whatever it has learned and experienced, and emulates scenarios.
