An analysis of the processing of olfactory information in the human body

The integration of gustatory and olfactory information is essential to the perception of flavor human neuroimaging experiments have pointed to the gustatory cortex (gc) as one of the areas involved in mediating flavor perception although gc's involvement in encoding the chemical identity and . Highly developed olfactory system to detect environmental information relevant for survival a dog's sense of smell is many orders of magnitude more sensitive than a human's. Altered olfactory processing of stress-related body odors and artificial odors in patients with panic disorder the data analysis was (2009) the neuronal .

The functional analysis of ectopic ors in the cardiovascular system is of particular interest because they have an enormous potential to operate as the main carrier of endogenously and exogenously derived odorants throughout the entire human body. Intuitive eating is inversely associated with body weight status in the general population-based nutrinet-santé study taste and olfactory processing in the . Olfactory stimuli even at levels below conscious perception, (4-7) behavioral, anatomical, and neurofunctional evidence exists supporting the likelihood of an innate olfactory-visual functional connection in the human brain (8-43). Human neural substrate specific for olfactory naming as revealed by the cross-task contrast analysis the left cuneus is shown the slice is displayed according to radiological convention.

All olfactory signals meet in the olfactory bulb where the information is distributed to two of the human body the second major information pathway is to the . Functions of cells and human body 3 taste and smell according to some authors there are two neuronal pools for processing the olfactory information: 1 . Next, we hypothesised that if cyclic changes in olfactory processing are odor-specific and tuned to biologically relevant odors, we should find changes in detection thresholds only for odorants found in body odor, or for those that are perceptually similar to it. As mentioned in the previous description of the olfactory process, the information captured by the sense of smell goes from the olfactory bulb to other structures of the limbic system the limbic system is a network of connected structures near the middle of the brain linked within the central nervous system.

This side view of the human head shows the olfactory bulb located immediately above the olfactory receptor cells in the olfactory epithelium lining the upper nasal passages the pair of olfactory bulbs is located just below the large frontal lobes of the brain. Human sensory reception: human sensory reception, means by which humans react to changes in external and internal environments ancient philosophers called the human senses “the windows of the soul,” and aristotle described at least five senses—sight, hearing, smell, taste, and touch. An additionally performed whole brain analysis did not show activation differences in areas other than those related to olfactory processing discussion the present results obtained in a large sample indicate that handedness plays no major role in the passive processing of olfactory information.

We showed how cognitive, semantic information modulates olfactory representations in the brain by providing a visual word descriptor, “cheddar cheese” or “body odor,” during the delivery of a test odor (isovaleric acid with cheddar cheese flavor) and also during the delivery of clean air. In patients with nasal polyposis, the differences between orthonasal and retronasal function may be related to the growth pattern of the polyps, which changes the orthonasal access of odorants to the olfactory cleft. Between the olfactory environment, simulated in terms of different odor concentrations, and a sub-population of intrinsic mushroom body neurons (kenyon cells) was calculated to quantify the efficiency of information transmission.

Given this diffuse nature of the information processed by the ob, it is conceivable that the larger the number of these neurons in the olfactory bulb, the more capable it becomes for processing more information to be analyzed by the piriform cortex, cortical amygdala, and other ob targets. The olfactory bulb (ob) is the first site for the processing of olfactory information in the brain and its deregulation is associated with neurodegenerative disorders although different efforts have been made to characterize the human brain proteome in depth, the protein composition of the human ob remains largely unexplored. The olfactory cortex receives signals from the olfactory bulb for processing and identifying odors in all, limbic system structures take information perceived from the five senses, as well as other sensory information (temperature, balance, pain, etc) to make sense of the world around us. In sum, biologically oriented olfactory processing may occur from the beginning of the cortical relay (in the apc), steering downstream analysis to convey motivational and affective information grounded in a given internal state (eg, anxious state).
