SYMPOSIUM
CELL TYPES IN TASTE BUDS AND TENTACLES
Chair/Organizer: Thomas Finger, Sue Kinnamon

This symposium will discuss the current thinking about the diversity of cells within taste buds and octopus suckers. While octopus suckers may seem an odd juxtaposition, (why not drosophila?), both taste buds and sucker taste receptor cells share the property of being specialized epithelial cells rather than being neurons as in arthropod taste organs. Both suckers and taste buds share the property of possessing different morphological types of receptor cells that correlate with functional properties. Vertebrate taste buds are classically described as possessing 3 types of elongate taste cells yet recent studies suggest additional cell types exist and raise the question of how to define cell types in any chemoreceptor system.

SATIETY-BASED MODULATION OF CHEMOSENSORY PROCESSING ACROSS ORGANISMS
Chair/Organizer: Thorsten Kahnt, Laura Shanahan

It is well-appreciated that chemosensory perception and feeding behaviors are modulated by satiety, metabolic state, and body weight via central and peripheral brain mechanisms. The goal of this symposium is to bring together researchers who are seeking to understand these complex interactions at complementary levels through their groundbreaking work in organisms ranging from invertebrates to primates. Dennis Mathew will present data on how anorectic peptides modulate the function of olfactory neurons across satiety states in Drosophila larvae, and how dysregulation of peripheral mechanisms influences feeding behavior and animal physiology. Matthew Gardner will present data on how satiety-related changes in choice behavior depend on baseline preferences in rats, and the role of orbitofrontal cortex in mediating this relationship. Maia Pujara will discuss findings on how interactions between orbitofrontal cortex and amygdala bias behavior when food palatability changes in nonhuman primates. Finally, Laura Shanahan will present work on how satiety influences perceptual decision-making and neural responses to food odors in human olfactory cortices. Together, these speakers will provide an overview of recent research on how satiety impacts chemosensory behavior in different species and the neural mechanisms driving satiety-dependent changes. By exploring this topic from a cross-species perspective, the symposium will highlight parallels in chemosensory processing across organisms, from simple to complex. Delving into the fascinating relationship between satiety and chemosensation is critical and timely given the profound impacts of the chemical senses on food intake and obesity.

SYMPOSIUM
MAX MOZELL: THE WORK LIVES ON
Chair/Organizer: Theresa White

Max Mozell, one of AChemS’ founders, passed away in March of 2020. Max's life in research was dominated by the study of olfactory perception and the effects of its loss on the patients with olfactory loss that he saw at the Smell and Taste Disorders Clinic at SUNY Upstate Medical University in Syracuse. This symposium is meant to honor his contributions to chemosensory research by looking at the latest developments in our understanding of the events in the nasal cavity. One of the things that Max would often say is that although many mysteries remain in understanding olfactory perception, at least one aspect is clear: if molecules from odorous substances can’t reach the olfactory receptors, there can be no perception. The airflow to deliver the molecules and the way that the molecules interact with the nasal mucosa are therefore central to the olfactory perceptual process. Changes in either the number of molecules or their distribution (and sorption) on the mucosa then alters incoming olfactory information, possibly resulting in dysosmia. This symposium will focus on recent findings in the peripheral olfactory system involving sniffing behavior, odor sorption, and molecular biology, as well as their application to clinical chemosensory disorders.

NON-WEIRD HUMAN CHEMOSENSORY SCIENCE
Chair/Organizer: Maria Velduizen, Valentina Parma

As chemosensory scientists, we are called to uncover and solve as a community open problems related to the chemical senses. Such problem-solving is inextricably intertwined with the societies we live in, and the chemical senses may be the senses that are most acutely affected by culture, environment, social race and geography. As a result, chemosensory knowledge is biased towards Western, educated, industrialized, rich and democratic (WEIRD) populations and research areas. It is a missed opportunity to not conduct more inclusive and collaborative research to solve complex chemosensory problems which often progress thanks to diverse perspectives, and the accumulation of big-data. In this symposium we propose themes in the literature, methodologies and approaches that provide advancements in chemosensory science that can be widely and cross-culturally applicable. How can we use olfactory testing flexibly, for example for screening during a pandemic? How does culture shape odor awareness and, more in general our (chemo)sensory perception? How can we link basic scientific chemosensory discoveries to the lived experience of patients, in ways that makes patients feel heard and reinforces confidence in science?
