3. Anatomy of the mammalian olfactory system 3.1. Olfactory epithelium; a sheet of olfactory
sensory neurons 3.2. Olfactory bulb; the first relay station in the central olfactory system 4 …

In mammals, olfactory sensory perception is mediated by two anatomically and functionally
distinct sensory organs: the main olfactory epithelium (MOE) and the vomeronasal organ …

Using their senses of taste and smell, animals recognize a wide variety of chemicals. The
nematode C. elegans has only fourteen types of chemosensory neurons, but it responds to …

Neurexins, a family of cell surface proteins specific to brain, are transcribed from two
promoters in three genes, resulting in three a-and three I~-neurexins. In situ hybridization …

The ability of mammals to discriminate thousands of structurally diverse odorants appears to
derive from the existence of a multigene family that encodes∼ 1000 different odorant …

AN important feature of natural killer (NK) cell activity is the lysis of cells that have
extinguished expression of some or all class I major histocompatibility (MHC) molecules1-7 …

In mammals, odors are detected by-1000 different types of odorant receptors (ORs), each
expressed by a fraction of neurons in the olfactory epithelium. Neurons expressing a given …

A systematic analysis of parthenogenetic (PG) cell fate within the central nervous system
(CNS) was made throughout fetal development and neonatal and adult life. Chimeras were …

The detection and discrimination of odorants in mammals is thought to be mediated by a
family of lOO-1000 seven transmembrane domain receptor proteins, although none of these …

Recent work on the mammalian olfactory system shows that sensory neurons expressing the
same type of odor receptor converge their axons onto one or a few glomeruli. This nearly …
