Olfaction, or as it is more commonly known, the sense of smell, is of great importance for species survival in terms of both reproduction and food selection, especially when taken together with the sense of taste (gustation). The information on this page is not intended to be a substitution for diagnosis, treatment, or informed professional advice. The basic mechanism of olfaction may seem straightforward. In terrestrial vertebrates, odorants are volatile chemicals of various classes (aliphatic, cyclic, aromatic, etc.). During the past 6 years, different studies on the evolution of the OR genes in mammals have pointed out the reduction of the functional fraction of the OR gene repertoire during primate evolution leading to a restricted set of functional OR genes in humans (see Evolution of Vertebrate Olfactory Subsystems). A number of reviews have been published on the principles of olfaction (Moulton, 1967; Keverne, 1999; Krieger and Breer, 1999; Laurent, 1999; Mombaerts, 1999, 2001a, 2004a; Mori et al., 1999; Firestein, 2001; Gaillard et al., 2004a). Maslow Psychology And Olfaction Psychology Definition is best in online store. Adult mysticetes, while possessing a vastly reduced olfactory system, have maintained small olfactory bulbs, a thin olfactory peduncle, and an olfactory tubercle (Oelschlager and Oelschlager, 2002). Does the sense of smell involve the perception of odor objects? See also: Olfactory Bulb. Wilson, in Encyclopedia of Neuroscience, 2009. Term. In: Kaas JH (ed.) EDWARD GOLDSON, ... DESMOND P. KELLY, in Developmental-Behavioral Pediatrics, 2008. In summary, auditory, visual, and somatosensory information is relayed through separate parts of the thalamus and reaches the sensory cortex and lateral amygdala through separate, parallel pathways. It is at the threshold between the external and internal worlds. The Psychology of Olfaction: A Theoretical Framework with Research and Clinical Implications. Olfaction definition is - the sense of smell. The olfaction- Hyposmia refers to diminished functioning that may be specific to a particular odorous compound (also referred to as specific anosmia). January « 2009 « California Life: Better Than Happy Hour. Taste, on the other hand, is also associated with food-related behaviors, but those that are more of a reflexive nature, such as ingestion, biting, and swallowing of food; for catfishes, taste also participates directly in the localization of the food source (Hara, T. J., 1993; Sorensen, P. W. and Caprio, J., 1998). Traumatic injury can include shearing of the olfactory nerves, hemorrhage into the olfactory bulb, and fractures of the cribriform plate, but their exact effect on chemosensation is unclear. Finally, Maurage et al. Olfaction is a particularly interesting sensory-perceptual modality, as it is the only sense that initially bypasses thalamic input and may provide a direct assessment of the functional integrity of the orbitofrontal cortex, a brain region that appears to be particularly affected by sleep deprivation (Thomas et al., 2000) and is critical to a number of emotional and cognitive processes (Killgore and McBride, … Oxford: Academic Press. It is important not only for the detection of odors, but also for the enjoyment of food, since flavor is a blend of taste and smell. Medicationsm including opiates and antibiotics such as doxycycline, and anesthetics, including tetracaine, can inhibit smell. You should not take any action or avoid taking any action without consulting with a qualified mental health professional. A frequently reported finding in age-related sensory impairment is that olfaction shows consistent and uniform decline with age. Recent Examples on the Web Fortunately, Dávalos’ former Ph.D. student Laurel Yohe is a leading researcher in bat olfaction. mental flexibility and set-shifting on a temporally contiguous trail-making test), these findings were suggested to occur independently of global declines in alertness. Olfaction, the sense of odor (smell), is the detection of chemicals dissolved in air (or in water, by animals that live under water). What does olfaction mean? When you receive a beautiful bouquet of roses, for example, chemical compounds from the flowers travel through the air and hit your nose. ADVERTISEMENTS: Perception: Meaning, Definition, Principles and Factors Affecting in Perception! A. and Caprio, J., 2004), and the feeding behaviors controlled by the two are not identical but are overlapping. Definition. Studies using smell for attractiveness ratings show that men and women are susceptible to pheromones and rate the opposite sex as more or less attractive depending on their hormonal state and the hormonal state of the opposite sex (Mostafa, Khouly, & Hassan, 2012).

Comparison of the sensory pathways through the thalamus to the cortical and amygdalar targets in mammals. The importance of the sense of smell and taste is generally underappreciated in everyday society. Joanne_S6. Killgore, in Progress in Brain Research, 2010. Kringelbach, in Brain Mapping, 2015. Olfaction has many purposes, including detecting hazards, pheromones, and plays a role in taste. Often the existence of mental imagery is demonstrated by asking one’s reader to volitionally generate a visual object, such as closing ones eyes and imagining an apple. lisa6394. 2015. Smell (Olfaction) The other special sense responsive to chemical stimuli is the sense of the smell, or olfaction. Olfaction, Taste, and Cognition. ‘Like olfaction, the sense of taste is a chemical sense.’ ‘While the mechanisms of salmonid homing are not completely understood, it is known that adult salmon continuously utilize two of their primary sensory systems, olfaction and vision, during homing.’ The authors of this volume have collected and evaluated the comparative anatomy, electron microscopy, electrophysiology, genetics, psychology, chemistry, and biophysics of the olfactory system and then indicated their roles in animal behavior. Olfaction has been completely lost in adult odontocetes. We have more information about Detail, Specification, Customer Reviews and Comparison Price. olfaction: [ smel ] the sense that enables one to perceive odors; it depends on the stimulation of sense organs in the nose by small particles carried in inhaled air. Everyday different stimuli around us will be stimulating our sense organs. Joanne_S6. Define gustation. People who lose a minor sense such as olfaction (smelling) or gustation (tasting) are quite dis­turbed by their handicap. Thalamic nuclei relay auditory, visual, and somatosensory information to the striatum and lateral amygdalar nucleus, as well as to the sensory cortical areas (Figure 4). Odorants are small volatile compounds with molecular mass less than 300 Da. This is how your paper can get an A! Researchers discover how mosquito brains work to hone in on a target The findings provide proof of principle for an approach that has the potential to be of broad utility for a range of clinical conditions causing loss of olfaction . Many advances have been made in the past fifty years in the study of olfaction, probab… One category is a polar functional group that contains an oxygen, a nitrogen, or a sulfur atom. However, the chemical specificity and the specific functions of the two chemosensory systems to these compounds can be quite distinct (Caprio, J., 1977; Goh, Y. and Tamura, T., 1980; Kohbara, J. et al., 1992; Nikonov, A. The olfactory receptor neurons are incorporated into a limited region of the nasal epithelium in the superior nasal cavity. Psychologists study olfaction to learn how people process information through smell and how odors affect their behavior. Olfaction, or the sense of smell, is the process of creating the perception of smell. This article outlines the human olfactory system and pathways from the olfactory epithelium to the olfactory cortices. Add flashcard Cite Random These criteria, derived from theories of vision, have been applied to olfaction in recent philosophical debates about psychology. Psychology Definition of OLFACTION: noun. OTHER SETS BY THIS CREATOR. Olfaction is mediated by a vast variety of odorants that are inhaled into the nose. Mothers are able to recognize the smell of their newborn babies (and vice versa) after prior exposure of as little as 1 h (Porter, 1998). It is essential for survival by permitting the location of food, mates, and predators, although in humans, olfaction is often viewed as an esthetic sense capable of triggering emotion and memory. Olfaction, or smell, occurs when chemicals stimulate olfactory receptors high in the nasal cavity. New York: Cambridge University Press. Smell (Olfaction) Olfactory receptor cells are located in a mucous membrane at the top of the nose. I will call in short term as Maslow Psychology And Olfaction Psychology Definition For people who are searching for Maslow Psychology And Olfaction Psychology Definition review. Derby, in The Senses: A Comprehensive Reference, 2008. These observations led to the hypothesis that the size of the functional OR repertoire reflects the olfactory needs and hence the olfactory capacity/ability of an organism. Bruce, M.R. Throughout human evolution, our sense of smell has been a key to our survival. D.A. Olfaction is a strongly evaluative sense in which perception and judgment are deeply entangled. Joanne_S6. Olfaction. (article twenty-third) point to the role of olfaction in the establishment of alcohol dependence. In most studies, discerning whether loss in olfaction is due to aging per se or to factors extrinsic to the aging process (e.g., smoking, chemical exposure, head injury) is difficult. Olfaction is detected in the main olfactory organ and the vomeronasal organ, although many aquatic mammals and humans lack a vomeronasal organ. ‎ABSTRACT This review centers on sensation and perception literature regarding olfaction as relevant to forensic examination from the perspective of rules of evidence, differential psychology, and psychophysics. Olfaction in catfishes, however, is essential for the discrimination of different amino acid stimuli in a learning paradigm (Valentinčič, T. et al., 1994; 2000b; Valentinčič, T., 2004). Modified from Bruce LL and Neary TJ (1995) The limbic system of tetrapods: A comparative analysis of cortical and amygdalar populations. Although lower animals have a more highly developed olfactory system, this chemical sense persists in humans. Joanne_S6. This region is referred to as the olfactory epithelium and contains bipolar sensory neurons with dendrites extending from the apical surface of the epithelium into the mucus lining the nasal cavity.

AP PSYCH SMELL 17 Terms. Search Funded PhD Projects, Programs & Scholarships in Psychology, olfaction. Ascending through the cribriform plate of the ethmoid bone, the olfactory nerve terminates in the olfactory bulb at the base of the frontal lobe. Olfaction and Gustation. The vomeronasal organ detects heavy odor molecules and projects to the accessory olfactory bulb, which in turn projects to most of the medial amygdala and the posterior medial cortical amygdala. AP Psychology - Kinesthetic & Vesibular - Chapter 3 13 Terms. These observations combined with the fact that olfactory neurons project directly to the amygdala and hippocampus without a thalamic relay suggests a prominent role for olfaction in mediating hedonic experience. (d) Frog: Ac, accumbens; D, diagonal band nucleus; DP, dorsal pallium; Ea, anterior entopeduncular nucleus; LP, lateral pallium; LPv, ventral part of lateral pallium; LS, lateral septum; MA, medial amygdala; MP, medial pallium; POa, anterior preoptic area; St, striatum; StC, caudal striatum; StD, dorsal striatum. The sense of olfaction is complex. There are also many other involvements of olfaction in animal behavior, not the least being communication. However, they are not really minor. These findings were replicated in a second independent sample following 52 h of sleep deprivation (McBride et al., 2006). Olfaction is involved in the detection and search for food and is uniquely implicated in the detection of pheromones and other chemicals that provide information concerning sex, social interactions, alarm, and homing. In women, the olfaction sense is … Interestingly, both cetaceans and primates (albeit less extensively) underwent a reduction of olfaction during their evolution. The other special sense responsive to chemical stimuli is the sense of the smell, or olfaction. This material may not be reprinted or copied for any reason without the express written consent of AlleyDog.com. RegalTutors TEACHER. This is primarily based on experimental work in other animals and in particular using new evidence from functional imaging studies in humans. Moreover, the somatosensory stimulation associated with airflow in the nose is represented by neural activity in both human olfactory bulb (Hughes, J. R. et al., 1969) and olfactory cortex (Sobel, N. et al., 1998), and it is necessary for olfactory perception. However, anosmic rainbow trout are incapable of initiating feeding in response to these chemical cues, in spite of a fully functioning taste system (Valentinčič, T. and Caprio, J., 1997). Odor perception is influenced by many factors unique to each individual as well as external environmental factors. However, in most psychophysical studies, preventing sniffing significantly alters the behavior under investigation. RegalTutors TEACHER. AP Psychology - Kinesthetic & Vesibular - Chapter 3 13 Terms. Odor can reach these receptors from the nostrils during inhalation and from the back of the nasopharynx during chewing and swallowing (which probably explains the close links between taste and smell). natalienn7. Types of Sensations 3. 125–156. The olfaction is physiologically quite similar to the gestation system because of the use of the chemoreceptors which play a key role in discerning the information about the substances.
