Does every nerve ending send information to the brain separately? Is there a nerve path (I don't know their scientific name) from every nerve ending to the brain; or are they sent to brain from the same paths in the dorsal root ganglion? If not, how can we determine the (almost) exact location of pain in our hand?
I am not very familiar with the biology except the lessons I had taken in the high school. So please try to use daily language explaining this.
