How do sensory neurons share information in the brain?
Generally what happens is that incoming information goes to the main center in the brain where that kind of information is processed: visual, for example, goes to the occipetal lobes, hearing goes to a temporo-parietal area, touch to the sensory strip of the parietal lobes, and so forth. Once the info gets there and is processed then, it would be sent out to other areas of the brain that further process it, parti- cularly the limbic system where the info is checked against memory (what’s new and what’sold in this info?) and for danger (is this a threat to survival of any kind?). All parts of the brain are con- nected to all other parts, and the information can be exchanged back and forth indefinitely. So I think the answer to your question is that the incoming nerves themselves are not connec- ted to the whole brain but to some some specific “module” which is directly connected to several others, which are directly con- nected to several others, and so on.
