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.
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 olfactory system, is the sensory system used for the sense of smell (olfaction). Olfaction is one of the special senses directly associated with specific organs. Most mammals and reptiles have a main olfactory system and an accessory olfactory system. The main olfactory system detects airborne substances, while the accessory system senses ...
Auditory imagery pertains to sounds, noises, music, or the sense of hearing. (This kind of imagery may come in the form of onomatopoeia). Olfactory imagery pertains to odors, aromas, scents, or the sense of smell. Gustatory imagery pertains to flavors or the sense of taste. Tactile imagery pertains to physical textures or the sense of touch.
Olfactory imagery research shows activation in the anterior piriform cortex and the posterior piriform cortex; experts in olfactory imagery have larger gray matter associated to olfactory areas. [37] Tactile imagery is found to occur in the dorsolateral prefrontal area, inferior frontal gyrus, frontal gyrus, insula, precentral gyrus, and the ...
Mary Cheves West Perky (1874–1940) was an American psychologist and one of the twenty-one female students who studied under Edward B. Titchener at Cornell University.She received a Ph.D. in 1910 for her groundbreaking work on visual, auditory, and olfactory imagery.
Olfactory artwork by Peter De Cupere. Olfactory art is an art form that uses scents as a medium. Olfactory art includes perfume as well as other applications of scent. The art form has been a recognized genre since at least 1980. [1] Marcel Duchamp was one of the first artists who pioneered with using scents in art. [2]
Unique to the olfactory and gustatory systems, at least in mammals, is the implementation of both peripheral and central mechanisms of action. [ clarification needed ] The peripheral mechanisms involve olfactory receptor neurons which transduce a chemical signal along the olfactory nerve , which terminates in the olfactory bulb .
