	Olfaction - SourceryForge
		Olfaction, the sense of smell, is the detection of chemicals dissolved in air (or, by animals that breathe water, in water).
		As an exception among birds, olfaction is important in the tubenoses.
		In many species olfaction is highly tuned to pheromones; a male silkworm moth, for example, can smell a single molecule of bombykol.

	Olfaction - Wikipedia, the free encyclopedia
		Olfaction (the sense of smell) is the detection of chemicals dissolved in air.
		Olfaction is one of the five senses originally described by Aristotle.
		In many species, olfaction is highly tuned to pheromones; a male silkworm moth, for example, can sense a single molecule of bombykol.

	Olfaction and the Brain - Cambridge University Press
		Olfaction and its relation to mental health is an area of growing interest, evidenced by the 2004 Nobel Prize in Physiology or Medicine being awarded for discoveries relating to odorant receptors and the organization of the olfactory system.

	olfaction scientific topics
		Olfaction peculiarity lies in the necessity for the sensory cell to select the appropriate odorant (or pheromone), sometimes in very low abundance, among a complex mixture of molecules.
		Odorant detection is performed by sensory neurons in the olfactory epithelium located in the upper part of the nasal cavity, directly connected with the brain olfactory bulbs.
		These molecular events are involved in the first step of olfactory sensing, upstream the biochemical cascade that provokes the nervous influx, which results in a conscious recognition (odor) associated with the odorant.

	Olfaction and Memory
		Olfaction is the sensory modality that is physically closest to the limbic system, of which the hippocampus and amygdala are a part, and which is responsible for emotions and memory.
		For example, storage and decay processes, characteristics of memory processes, are not yet understood with respect to olfaction (1996).
		Olfaction therefore plays a part in an integrated system for recovering caches and finding hidden food.

	SMELL
		Also found in the nasal mucosa is a pigmented-type of epithelial cell: the depth of colour is often correlated with olfactory sensitivity, being light yellow in humans and dark yellow or brown in dogs.
		One possible explanation is that because olfactory centres (primary olfactory cortex, entorhinal cortex) are next door to regions where seizures begin in temporal lobe epilepsy, activity generated in these areas by the presentation of a smell prevents the spread of the synchronous activity from the epileptic focus.

	Olfaction in Courtship
		If no differences in behavior occurred, we could conclude either that female olfaction is not essential for normal courtship behavior or that other chemoreceptors compensate for the loss of olfaction.
		This indicates that male olfaction is not necessary for the normal sequence of lobster courtship behavior.
		The absence of male-male agonistic encounters suggests that male olfaction is involved in male dominance.

		Olfaction is less developed in humans than in other mammals such as rodents.
		The thalamic connections are thought to serve as a conscious mechanism for odor perception, while the amygdala and the entorhinal area are limbic system components and may be involved in the affective components of olfaction.
		Investigations of regional cerebral blood flow have demonstrated a significant increase in the amygdaloid nucleus with the introduction of a highly aversive odorant stimulus, and this has been associated with subjective perceived aversiveness.

	Avian Olfaction
		Bang's research sparked a wave of olfaction research that has broadened the horizons of the understanding of how birds smell.
		While much progress has been made in the last few decades in the study of avian olfaction, there is still much more to find out.
		Olfaction in species with less developed olfactory neuroanatomy, homing, migration, potential odorants, and the role of pheromones are but a few areas that would benefit from further research.

	Olfaction - A Review
		Smell (or Olfaction) allows vertebrates and other organisms with olfactory receptors to identify food, mates, predators, and provides both sensual pleasure (the odor of flowers and perfume) as well as warnings of danger (e.g., spoiled food, chemical dangers).
		This paper will explore the current status our understanding of olfaction and provide in some detail the possible molecular interactions that specify odorant signaling.
		Odorants are volatile chemical compounds that are carried by inhaled air to the Regio olfactoria (olfactory epithelium) located in the roof of the two nasal cavities of the human nose, just below and between the eyes.

		However, the detection and processing of odor by the body is not well understood.
		Despite the importance of olfaction (sense of smell) to our daily lives, the chemical aspect to olfaction was not given much attention by the scientific community until the 1980's.
		There is a variety of theories proposed to explain olfaction, but there is no general agreement.

	The Vivid World of Odors
		In A Natural History of the Senses, poet Diane Ackerman notes that it is almost impossible to explain how something smells to someone who hasn't smelled it.
		Nor can odors be measured on the kind of linear scale that scientists use to measure the wavelength of light or the frequency of sounds.
		"It would be nice if one smell corresponded to a short wavelength and another to a long wavelength, such as rose versus skunk, and you could place every smell on this linear scale," says Randall Reed, an HHMI investigator at the Johns Hopkins University School of Medicine who has long been interested in olfaction.

	Olfaction (Site not responding. Last check: 2007-10-20)
		The senses of olfaction (smell) and taste are very closely associated.
		The receptors of both senses are chemoreceptors and, thus, are able to detect the presence of a chemical once the chemical has gone into solution in the liquid coating of the receptors' cell membranes.
