Connexon-Connexon mediated adhesion domains. In addition to forming functional intercellular channels, docking of compatible connexons between radial glia (yellow) and NPCs (gold) directs migration of NPCs Docking and undocking enables the “rolling” of NPCs along their radial glial guides to their final location before terminal differentiation. Adhesion can be channel-independent without requiring exchange of small molecules or functional channel opening
