The Role of Cortical Displays in Brain Development

I always thought in my ignorance that cortical displays here was a migration problem rather like of course periventricular nodular heterotopia and band heterotopia are migrations. I sort of half expected this paper to come in with a whole load about the embryology of the brain development and it's not mentioned. It does seem it's mainly a genetic thing and if there is any migration then that's very very genetically determined and locally determined so there's a lot to learn about this. As there is about coding. So the next thing is how is outpatient neurology diagnostic coding for people who have focal onset epilepsy.
