✦ Synopsis
In adult Xenopus, the nasal cavity sioned side, reduction of the region of the glomerular is divided into separate middle (MC) and principal layer of the olfactory bulb receiving MC afferents (PC) cavities; the former is used to smell water-borne odorants, the latter air-borne odorants. Recent work ranged from 70% to 95%. PC afferents did not occupy has shown that olfactory neurons of each cavity exregions of the olfactory bulb deprived of MC afferents. press a distinct subclass of odorant receptors. More-These results support a model in which intrinsic cues over, MC and PC axons project to distinct regions of in the olfactory bulb control the projection pattern the olfactory bulb. To examine the developmental baattained by ingrowing olfactory axons. ᭧ 1997 John sis for this specificity in the olfactory projection, we
