(hp1, hp2: hypothalamus prosomeren thumb|400px|Schemata illustrating embryonic (a) and adult (b) location and abbreviations for neuromeres within the prosomeric model. thumb| Diagram of early embryonic brain formation Neuromeres are distinct groups of neural crest cells, forming segments in the neural tube of the early embryonic development of the brain. There are three classes of neuromeres in the central nervous system – prosomeres (for the prosencephalon), mesomeres (for the mesencephalon) and rhombomeres (for the rhombencephalon) that will develop the forebrain, midbrain, and hindbrain respectively.
Neuromeres can then be divided up so that each segment is carrying different and unique genetic traits, expressing different features in development.
