The axons of the olfactory, vomeronasal, and terminal nerves, also NCAM\u2010immunoreactive, grow into the cellular aggregate, which as development proceeds, becomes continuous with the rostral tip of the forebrain. The lateral and more rostral part of the cellular aggregate receives the ingrowing axons of the olfactory nerves and becomes the olfactory nerve layer of the olfactory bulb. The medial, more caudal part receives the central processes of the vomeronasal and terminal nerves. The vomeronasal nerve ends in the accessory olfactory bulb. The central processes of the terminal nerve end in the medial forebrain. Luteinizing hormone\u2010releasing hormone (LHRH)\u2010immunoreactive neurons, like the vomeronasal and terminal nerves, originate from the medial part of the olfactory pit. These LHRH cells migrate into the brain along and within a scaffolding formed by the NCAM\u2010immunoreactive axons of the vomeronasal and terminal nerves, and they are never seen independent of this NCAM scaffold as they cross the nasal lamina propria.<\/jats:p><jats:p>The results suggest that: (1) NCAM is likely to be necessary for scaffold formation, and (2) the scaffold may be essential for the subsequent migration of LHRH neurons into the brain. Because they aggregate, migrating LHRH\u2010immunoreactive neurons, on which we did not detect NCAM immunoreactivity, may interact via other cell adhesion molecules (CAM). Inasmuch as the interaction between the LHRH\u2010immunoreactive neurons and the NCAM\u2010immunoreactive scaffold is heterotypic, the possibility of a heterophilic (NCAM to other CAM) interaction is not ruled out. These findings focus our attention on the functional role of NCAM in this migratory system. \u00a9 1992 Wiley\u2010Liss, Inc.<\/jats:p>","DOI":"10.1002\/cne.903210102","type":"journal-article","created":{"date-parts":[[2005,1,1]],"date-time":"2005-01-01T23:02:47Z","timestamp":1104620567000},"page":"1-18","source":"Crossref","is-referenced-by-count":113,"title":["Immunocytochemical demonstration of neural cell adhesion molecule (NCAM) along the migration route of luteinizing hormone\u2010releasing hormone (LHRH) neurons in mice"],"prefix":"10.1002","volume":"321","author":[{"given":"Marlene","family":"Schwanzel\u2010Fukuda","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.","family":"Abraham","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K.
