Neurodiversity means accepting those whose various nervous system components behave as generally expected (neurotypical), as well as those whose nervous systems don't (autism, migraines, scotopic sensitivity, sensory hyperacuity, parkinson's, ALS, etc.).
One of the challenges in building an effective team and a useful network of people to work with is to reach out widely enough to reach some people who have a diversity of background and experience. Seek representation from all corners including people from large and small cities, from a variety of ethnic and racial backgrounds, and with diverse religious, cultural, and economic backgrounds.
A parallel set of diversity-seeking looks to build connections with people who have diverse ways of perceiving the world. The neurotypical view of the world is best balanced with views from people who don't have nervous systems and sensory systems that perceive the world or act on those perceptions in the same way.
Neurodiversity is a word with some specific meaning within a community of people with autism-spectrum disorders, a community which I know only at the edges and can't count myself a core part of. In some ways I can only hope to approximate that perspective, e.g. in the occasional bits of assisted synesthesia that I try to sneak into my writing. If you are living in a neurotypical world, the insight from someone with diverse sensory perception can trigger the great weird ideas that you find when worlds that were once foreign to each other gain a bridge that helps pull good thoughts from one side to the other. Or, perhaps, I'm a neurodiverse individual in this collection, and you are neurotypical by comparison; it's so hard to tell sometimes.
