1878 Amer. Naturalist 12 811 Our author considers the body-segment of a vertebrate not as a single organ, but as the combination of a neuromere arising from the ectoderm with the scleromere and myomere arising from the mesoderm.

1897 Nat. Sci. Feb. 114 That..branch of morphology which deals with the nerve-segments of the head (cerebral neuromeres).

1947 A. D. Imms Outl. Entomol. (ed. 3) ii. 29 The first ventral nerve centre is the suboesophageal ganglion..formed by the fusion of the 4th to 6th neuromeres or ganglia of the mandibular, maxillary, and labial segments.

1989 Nature 2 Feb. 424/1 It is possible that segmentation is also an important pattern-forming process within the neural epithelium, where transient periodic swellings, neuromeres, have long been recognized.

1898 Amer. Naturalist 32 588 The two primary vesicles, fore-brain and mid-brain, are each of neuromeric value.

1933 Q. Rev. Biol. 8 250 Although embryology appears to indicate that the central nervous system has not had a segmental or neuromeric origin, a form somewhat simulating segmentation has been at least secondarily assumed.

2000 Mechanisms Devel. 90 105 We identified a series of eight transverse diencephalic domains suggestive of neuromeric subdivisions within the rostral brain.

† neuromerous adj. Obsolete rare Apparently only attested in dictionaries or glossaries.
