Abstract:
Feeding can be regulated by a variety of external sensory stimuli such as olfaction and gustation, as well as by systemic internal signals of feeding status and metabolic needs. Faced with a major health epidemic in eating-related conditions, such as obesity and diabetes, there is an ever increasing need to dissect and understand the complex regulatory network underlying the multiple aspects of feeding behavior. In this minireview, we highlight the use of Drosophila in studying the neural circuits that control the feeding behavior in response to external and internal signals. In particular, we

Abstract:
Olfaction in mammals is a dynamic process driven by the inhalation of air through the nasal cavity. Inhalation determines the temporal structure of sensory neuron responses and shapes the neural dynamics underlying central olfactory processing. Inhalation-linked bursts of activity among olfactory bulb (OB) output neurons [mitral/tufted cells (MCs)] are temporally transformed relative to those of sensory neurons. We investigated how OB circuits shape inhalation-driven dynamics in MCs using a modeling approach that was highly constrained by experimental results. First, we constructed models of c

Olfaction is an important neural system for survival and fundamental behaviors such as predator avoidance, food finding, memory formation, reproduction, and social communication. However, the neural circuits and pathways associated with the olfactory system in various behaviors are not fully understood. Recent advances in optogenetics, high-resolution in vivo imaging, and reconstructions of neuronal circuits have created new opportunities to understand such neural circuits. Here, we generated a transgenic zebrafish to manipulate olfactory signal optically, expressing the Channelrhodopsin (ChR2

Olfaction and satiety status influence each other: cues from the olfactory system modulate eating behavior, and satiety affects olfactory abilities. However, the neural mechanisms governing the interactions between olfaction and satiety are unknown. Here, we investigate how an animal’s nutritional state modulates neural activity and odor representation in the mitral/tufted cells of the olfactory bulb, a key olfactory center that plays important roles in odor processing and representation. At the single-cell level, we found that the spontaneous firing rate of mitral/tufted cells and the number

Abstract With less than a million neurons, the western honeybee Apis mellifera is capable of complex olfactory behaviors and provides an ideal model for investigating the neurophysiology of the olfactory circuit and the basis of olfactory perception and learning.

Abstract:
All an animal can do to infer the state of its environment is to observe the sensory-evoked activity of its own neurons. These inferences about the presence, quality, or similarity of objects are probabilistic and inform behavioral decisions that are often made in close to real time. Neural systems employ several strategies to facilitate sensory discrimination: Biophysical mechanisms separate the neuronal response distributions in coding space, compress their variances, and combine information from sequential observations. We review how these strategies are implemented in the olfactory system

Abstract:
Animals rely on olfaction to find food, attract mates, and avoid predators. To support these behaviors, they must be able to identify odors across different odorant concentrations. The neural circuit operations that implement this concentration invariance remain unclear. We found that despite concentration-dependence in the olfactory bulb (OB), representations of odor identity were preserved downstream, in the piriform cortex (PCx). The OB cells responding earliest after inhalation drove robust responses in sparse subsets of PCx neurons. Recurrent collateral connections broadcast their activat

Olfaction has a direct influence on behavior and cognitive processes. There are different neuromodulatory systems in olfactory circuits that control the sensory information flowing through the rest of the brain. The presence of the cannabinoid type-1 (CB1) receptor, (the main cannabinoid receptor in the brain), has been shown for more than 20 years in different brain olfactory areas. However, only over the last decade have we started to know the specific cellular mechanisms that link cannabinoid signaling to olfactory processing and the control of behavior.

Abstract This chapter provides a comprehensive overview linking the sense of smell to the field of emotion. The authors focus on the evolution of the olfactory system and its anatomical pathways, including overlapping structures with emotional processing circuits. The chapter proceeds with a detailed analysis of the functional relationship between olfaction and emotion based on the following topics: odors and leading emotional reactions; odors as chemosignals within social communication (focusing on a definition of chemosignals; chemosignals and emotional contagion; and chemosignals within intimate relationships); and odors as a basis for multisensory integration in the context of emotional processing. Throughout the chapter, the authors present a broad range of experimental studies including behavioral and neuroimaging investigations, as well as implications of research on patients with olfactory deficits.

Abstract:
Abstract The chemical senses—taste and smell—are the oldest animal senses. They are characterized by a multidimensional and diverse stimulus space, consisting of many molecules that cannot be classified along any narrow set of dimensions. In the case of the olfactory system, animals detect low molecular weight volatile chemicals (i.e. odorants) with the help of specialized olfactory sensory neurons that express one or a few ligand-binding odorant receptor proteins. Animals cope with the problem of recognizing an extremely large number of different odorants by programming a very large number of functionally different olfactory neurons. Odours activate these neurons and generate characteristic activity patterns across the neuron population, which are relayed to second-order olfactory neurons. The entire available raw information about the animal’s olfactory environment is present in these patterns; however, olfactory information is further processed before it is relayed to higher-order brain centres. Drosophila melanogaster provides an attractive model organism for studying olfaction, as it allows genetic, molecular, and physiological analyses. In recent years, immense progress has been achieved in understanding the olfactory neuronal circuits that underlie the coding and processing of odours in Drosophila. Here, the chapter reviews our present state of knowledge regarding the anatomical architecture of the fly’s olfactory system as well as giving recent insights into the coding strategies of the different neuronal populations involved.
