Odor signals received by odorant receptors (ORs) expressed by olfactory sensory neurons
(OSNs) in the olfactory epithelium (OE) are represented as an odor map in the olfactory bulb …

Sensory information is transmitted to the brain where it must be processed to translate
stimulus features into appropriate behavioural output. In the olfactory system, distributed …

Constitutive heterochromatin is traditionally viewed as the static form of heterochromatin that
silences pericentromeric and telomeric repeats in a cell cycle-and differentiation …

In the piriform cortex, individual odorants activate a unique ensemble of neurons that are
distributed without discernable spatial order. Piriform neurons receive convergent excitatory …

Each olfactory sensory neuron (OSN) in mouse chooses one of 1,200 odorant receptor (OR)
genes for expression. OR genes are chosen for expression by greatly varying numbers of …

The olfactory receptor (OR) genes are the largest mammalian gene family and are
expressed in a monogenic and monoallelic fashion in olfactory neurons. Using a high …

Background Parent-of-origin-dependent expression of alleles, imprinting, has been
suggested to impact a substantial proportion of mammalian genes. Its discovery requires …

Odorant receptor (OR) genes constitute with 1200 members the largest gene family in the
mouse genome. A mature olfactory sensory neuron (OSN) is thought to express just one OR …

Background Mitral and tufted cells are the projection neurons in the olfactory bulb,
conveying odour information to various regions of the olfactory cortex. In spite of their …

The olfactory system presents a practical model for investigating basic mechanisms involved
in patterning connections between peripheral sensory neurons and central targets. Our …
