Neuromere

Neuromeres are morphologically or molecularly defined transient segments of the early developing brain. Rhombomeres are such segments that make up the rhombencephalon or hindbrain. More controversially, some argue that there exist early developmental segments that give rise to structures of the midbrain (mesomeres) and forebrain (prosomeres).

Neurogenesis

General neural development/ neurulation/neurula	Notochord · Neuroectoderm · Neural plate (Neural fold, Neural groove)

Neural crest	Cranial neural crest (Cardiac neural crest complex) · Truncal neural crest

Neural tube	Rostral neuropore Neuromere/Rhombomere Cephalic flexure · Pontine flexure Alar plate (sensory) · Basal plate (motor) Glioblast · Neuroblast Germinal matrix

Eye development

Neural tube: Optic vesicle · Optic stalk · Optic cup

Surface ectoderm: Lens placode

Auditory development

Otic placode (Otic pit, Otic vesicle)

note: NS is mostly ectoderm, but mesoderm is precursor for epineurium, perineurium, and endoneurium
