OOPS, the Ontology for Odor Perceptual Space: from molecular composition to sensory attributes of odor objects [PDF]
, 2022 When creating a flavor to elicit a specific odor object characterized by odor sensory attributes (OSA), expert perfumers or flavorists use mental combinations of odor qualities (OQ) such as Fruity, Green, Smoky.

Categorical Dimensions of Human Odor Descriptor Space Revealed by Non-Negative Matrix Factorization [PDF]
, 2013 In contrast to most other sensory modalities, the basic perceptual dimensions of olfaction remain unclear. Here, we use non-negative matrix factorization (NMF) – a dimensionality reduction technique – to uncover structure in a panel of odor profiles ...

Topological reorganization of odor representations in the olfactory bulb. [PDF]
, 2007 Odors are initially represented in the olfactory bulb (OB) by patterns of sensory input across the array of glomeruli. Although activated glomeruli are often widely distributed, glomeruli responding to stimuli sharing molecular features tend to be ...

Dopaminergic modulation of odor responses by local interneurons in the olfactory bulb [PDF]
, 2011 The olfactory bulb is one of the few regions in the brain where dopamine is provided locally by an intrinsic population of GABAergic interneurons but their role in processing of sensory information remains ambiguous.
