| neurobiotactic movement | The streaming of nerve cells toward the area from which they receive the most stimuli. (05 Mar 2000) |
| neurobiotaxis | The theory that nerve cell bodies may move toward, or their axons may grow toward, the area from which they receive the most stimuli. Origin: G. Neuron, nerve + bios, life + taxis, arrangement (05 Mar 2000) |
| neuroblast | <embryology> Cells arising by division of precursor cells in neural ectoderm (neurectoderm) that subsequently differentiate to become neurons. (16 Dec 1997) |
| neuroblastoma | <oncology, tumour> Malignant tumour derived from primitive ganglion cells. Mainly a tumour of childhood. Commonest sites are adrenal medulla and retroperitoneal tissue. The cells may partially differentiate into cells having the appearance of immature neurons. The tumour shows a consistent deletion of the 1p36 region which is considered the site of the neuroblastoma I gene. Loss of the 1p36 region also correlates with amplification for the N-myc oncogene, particularly in later stages of the disease. Amplification of N-myc with DNA triploidy is associated with poor survival. Hereditary forms of the condition are rare and in such patients there is no risk for other cancers, which suggests a specificity of the antioncogene for neural tissues. (16 Dec 1997) |
| neuroborreliosis | Infla mmation or disease caused by infection of the central nervous system by a member of the genus Borrelia. It is frequently a late stage in the disease process, particularly in immunosuppressed individuals, such as those suffering from AIDS. (05 Mar 2000) |
