Dr. Maria Veldhuizen conducted a seminar at UMRAM\/Aysel Sabuncu Research Center on March 6, 2019.<\/p>\n\n\n\n
Maria Veldhuizen was trained as a psychophysicist in\ntaste, smell and flavor perception, both during her PhD with Dr. Jan Kroeze at\nUtrecht University in the Netherlands and post-doctoral fellowship with Dr. <\/p>\n\n\n\n
Lawrence Marks at The John B. Pierce Laboratory and Yale School of Medicine in New Haven, Connecticut, USA. Since joining Dr. Dana Small’s lab in 2006, in the department of Psychiatry at Yale School of Medicine , she has combined these skills with neuroimaging of chemosensory perception in humans using fMRI and advanced computational techniques such as network modeling and pattern analysis. She is interested in gustatory encoding, integration of taste and smell, and development of flavor preferences. One focus has been on how the human brain achieves attention to taste and how taste cortex interacts with other cortical areas under attention. She has also worked on the neural commonalities of sweet taste and sweet odors. Lastly she is specifically interested in understanding how the appreciation of a flavor develops by association with calories and interactions with metabolism in humans. Her future ambitions include employing non-invasive neuro-modulation as an intervention in obesity and writing a children’s book on taste and smell perception.<\/p>\n\n\n\n
Here her talk’s abstract:<\/p>\n\n\n\n
Food cues previously paired with calories become liked\nand facilitate the identification of reliable energy sources. Post-ingestive\nsignals related to nutrient metabolism are thought to be the primary drivers of\nthis reinforcement, however, the identity of the physiological signals\nregulating this remain elusive. In a series of neuroimaging and indirect\ncalorimetry human studies, we examine the relative roles of caloric load and\nperceived sweetness in driving metabolic, perceptual, gastric and brain\nresponses to sugared beverages. We demonstrate a non-linear association between\ncaloric load, metabolic response, and reinforcement potency, which is driven in\npart by the extent to which sweetness is proportional to caloric load. Altered\nmetabolism may lead to weight-gain over time. Thus these results suggest we\nneed to carefully consider the desirability of adjusting the fidelity between\nsweetness and calories in beverages.<\/p>\n","protected":false},"excerpt":{"rendered":"
