I have what I feel is a novel and potentially helpful observation in the field of neuroscience, which connects it to another field, but it is just that - an observation. If this needs to become publishable, do I need to develop an entire theory around it (which is difficult, given that neuroscience isn't dealing with the relatively "simpler" objects that we see in physics or mathematics). The other alternative is to gather as much evidence from prior studies as possible that point to the observation being valid.
How does someone who is theoretically inclined go about this?
