"Smell", from Allegory of the Senses by Jan Brueghel the Elder, Museo del Prado. An odor (American English) or odour (Commonwealth English; see spelling differences) is a smell or a scent caused by one or more volatilized chemical compounds generally found in low concentrations that humans and many animals can perceive via their olfactory system.
Odour is sensory stimulation of the olfactory membrane of the nose [1] by a group of molecules. [2] Certain body odours are connected to human sexual attraction. [3] [4] Humans can make use of body odour subconsciously to identify whether a potential mate will pass on favourable traits to their offspring.
In an odor recognition test participants are asked whether or not they recognize an odor. More specifically, a participant is subjected to a certain olfactory-related stimulus, and after a delay period is asked to decide if a probe (a stimulus that could or could not be the same as the initial stimulus) is the same as the one he/she initially ...
The Lady and the Unicorn, a Flemish tapestry depicting the sense of smell, 1484–1500. Musée national du Moyen Âge, Paris.. Early scientific study of the sense of smell includes the extensive doctoral dissertation of Eleanor Gamble, published in 1898, which compared olfactory to other stimulus modalities, and implied that smell had a lower intensity discrimination.
The anterior olfactory nucleus is the memory hub for smell. [24] When different odor objects or components are mixed, humans and other mammals sniffing the mixture (presented by, e.g., a sniff bottle) are often unable to identify the components in the mixture even though they can recognize each individual component presented alone.

In the latter cases, the belief arises via misinterpretation of the behavior of others or with the rationale that a disorder of smell which prevents self detection of the odor (i.e. anosmia) exists. In the cases where the non-existent odor can be detected, this is usually considered as phantosmia (olfactory hallucination).
With the heat kicking in, body odor has been on many people’s minds. Dermatologist Heather Kornmehl posted an Instagram video earlier this month explaining how “the potential for stinky ...
For example, the smell of a particular perfume might remind someone of a loved one, or the scent of freshly baked cookies could evoke childhood memories. Without the sense of smell, individuals with congenital anosmia may miss out on these powerful sensory experiences that enhance and enrich one's emotional lives and memories. [24] [25] [26] [27]
