  2. Olfactory bulb - Wikipedia

    en.wikipedia.org/wiki/Olfactory_bulb

    The olfactory bulb (Latin: bulbus olfactorius) is a neural structure of the vertebrate forebrain involved in olfaction, the sense of smell. It sends olfactory information to be further processed in the amygdala, the orbitofrontal cortex (OFC) and the hippocampus where it plays a role in emotion, memory and learning.

  3. Olfactory system - Wikipedia

    en.wikipedia.org/wiki/Olfactory_system

    Allomones include flower scents, natural herbicides, and natural toxic plant chemicals. The info for these processes comes from the vomeronasal organ indirectly via the olfactory bulb. [16] The main olfactory bulb's pulses in the amygdala are used to pair odors to names and recognize odor to odor differences. [17] [18]

  4. 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 ...

    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 brain’s ability to link smells with memories is deeply rooted in science. Dr Ameen-Ali explains that our brain’s “olfactory bulb” translates a scent as a kind of information, which is ...

    Connecting the olfactory bulb and the nasal cavity is the olfactory nerve. Some researchers worry the olfactory pathway may also be an entry point for microplastics getting into the brain, beyond ...

  8. Evolution of olfaction - Wikipedia

    en.wikipedia.org/wiki/Evolution_of_olfaction

    The main olfactory sense is derived from the more ancient neural system, broadly present across insects and mammals. [23] This system is specialized to detect volatile, airborne molecules. The accessory olfactory system is the more recently evolved structure, first appearing in the common ancestor of modern amniotes and amphibians.

  9. Olfactory nerve - Wikipedia

    en.wikipedia.org/wiki/Olfactory_nerve

    The specialized olfactory receptor neurons of the olfactory nerve are located in the olfactory mucosa of the upper parts of the nasal cavity.The olfactory nerves consist of a collection of many sensory nerve fibers that extend from the olfactory epithelium to the olfactory bulb, passing through the many openings of the cribriform plate, a sieve-like structure of the ethmoid bone.
