olfaction definition psychology

The gustatory system is used for taste discrimination, which tells the difference between foods using the taste receptors located on our tongues. (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. mental flexibility and set-shifting on a temporally contiguous trail-making test), these findings were suggested to occur independently of global declines in alertness. Psychology Definition of GUSTATION: Describes the sense of taste. 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. AP Psychology - Kinesthetic & Vesibular - Chapter 3 13 Terms. January « 2009 « California Life: Better Than Happy Hour. 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. 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). L.L. Similarly, when humans try to imagine an odor, they spontaneously sniff (Bensafi, M. et al., 2003b), and if this spontaneous sniffing is prevented, the vividness of their olfactory imagery is reduced (Bensafi, M. et al., 2005). The main olfactory organ detects light, airborne molecules and projects to the main olfactory bulb, which in turn projects as a superficial sheet over portions of the telencephalon. See also: Olfactory Bulb. n. The act or faculty of tasting. Copyright © 2021 Elsevier B.V. or its licensors or contributors. Finally, Maurage et al. Does the sense of smell involve the perception of odor objects? For example, dogs have about 100 times more olfactory receptor cells compared to humans. AP PSYCH SMELL 17 Terms. Psychology. Killgore, in Progress in Brain Research, 2010. Autism Spectrum Disorder (ASD) is a developmental disorder that involves impairments in social interaction and communication, challenges with … Olfaction is mediated by a vast variety of odorants that are inhaled into the nose. Caprio, J., 1977; Goh, Y. and Tamura, T., 1980; Kohbara, J. There is a solid rationale not to circumvent the specificities of olfaction and other forms of chemoreception when it comes to a comprehensive theory of the senses. ADVERTISEMENTS: In turn the brain will interpret these sensations. To understand the molecular feature maps in the olfactory bulb, it is important to summarize the knowledge of molecular features of odorants. 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, 2006). Working of Sensory System 2. It has been argued that compared to other animals, humans depend less on olfactory functions and more on other senses such as vision and hearing (Jacobs, 2009). When you receive a beautiful bouquet of roses, for example, chemical compounds from the flowers travel through the air and hit your nose.
