  2. Olfactory bulb - Wikipedia

    en.wikipedia.org/wiki/Olfactory_bulb

    The accessory olfactory bulb resides on the dorsal-posterior region of the main olfactory bulb and forms a parallel pathway. Destruction of the olfactory bulb results in ipsilateral anosmia, while irritative lesions of the uncus can result in olfactory and gustatory hallucinations. Flow of olfactory information from receptors to glomeruli layer

  3. Glomerulus (olfaction) - Wikipedia

    en.wikipedia.org/wiki/Glomerulus_(olfaction)

    These ORNs then project their axons to the olfactory bulb. In the olfactory bulb, the ORNs synapse with termination in the glomeruli. [6] Each glomerulus receives input from olfactory receptor neurons expressing only one type of olfactory receptor. The glomerular activation patterns within the olfactory bulb are thought to represent the quality ...

  4. Olfactory epithelium - Wikipedia

    en.wikipedia.org/wiki/Olfactory_epithelium

    The olfactory epithelium contains olfactory sensory neurons, whose axons innervate the olfactory bulb. In order for olfactory sensory neurons to function properly, they must express odorant receptors and the proper transduction proteins on non-motile cilia that extend from the dendritic knob in addition to projecting their axons to the ...

  5. Sense of smell - Wikipedia

    en.wikipedia.org/wiki/Sense_of_smell

    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.

  6. Brain - Wikipedia

    en.wikipedia.org/wiki/Brain

    The olfactory bulb is a special structure that processes olfactory sensory signals and sends its output to the olfactory part of the pallium. It is a major brain component in many vertebrates, but is greatly reduced in humans and other primates (whose senses are dominated by information acquired by sight rather than smell).

  7. Granule cell - Wikipedia

    en.wikipedia.org/wiki/Granule_cell

    This allows the granule cells to regulate the processing of the sensory input in the olfactory bulb. [21] The olfactory bulb transmits smell information from the nose to the brain, and is thus necessary for a proper sense of smell. Granule cells in the olfactory bulb have also been found to be important in forming memories linked with scents. [22]

  8. Mitral cell - Wikipedia

    en.wikipedia.org/wiki/Mitral_cell

    Mitral cells are a neuronal cell type in the mammalian olfactory bulb, distinguished by the position of their somata located in an orderly row in the mitral cell layer of the bulb. [4] They typically have a single primary dendrite, which they project into a single glomerulus in the glomerular layer, and a few lateral dendrites that project ...

  9. Olfactory glands - Wikipedia

    en.wikipedia.org/wiki/Olfactory_glands

    Olfactory glands, also known as Bowman's glands, are a type of nasal gland situated in the part of the olfactory mucosa beneath the olfactory epithelium, that is the lamina propria, a connective tissue also containing fibroblasts, blood vessels and bundles of fine axons from the olfactory neurons.
