Retronasal Odor Perception Requires Taste Cortex, but Orthonasal Does Not
Processing of Intraoral Olfactory and Gustatory Signals in the Gustatory Cortex of Awake Rats
TLDR
This study relied on multielectrode recordings to investigate how single GC neurons respond to intraorally delivered tastants and tasteless odorants dissolved in water and whether/how these two modalities converge in the same neurons and found that neurons in gustatory cortex can respond either exclusively to taste, exclusively to odorants, or to both (bimodal).
Chemosensory Convergence on Primary Olfactory Cortex
Food perception and preference formation relies on the ability to combine information from both the taste and olfactory systems. Accordingly, psychophysical investigations in humans and behavioral
Cortical Hub for Flavor Sensation in Rodents
TLDR
The emerging view pertaining to the multimodal processing of food and beverages is that the piriform, gustatory, and somatosensory cortical regions do not function solely as independent areas, but act as an intraoral cortical hub, simultaneously receiving and processing multimodals sensory information from the mouth to produce the rich and complex flavor experience that guides consummatory behavior.
Retronasal perception of odors
The Feasibility of Gelatin-Based Retronasal Stimuli to Assess Olfactory Perception
TLDR
The data demonstrate the feasibility of using solid-state gustatory stimuli to assess retronasal perception using gelatin-based stimuli delivered orally, and estimate vanillin thresholds for five healthy participants sampling small vanillin flavored gels.
Forthcoming in Sensory Individuals edited by Aleksandra Mroczko-Wąsowicz and Rick Grush. OUP Smelling Odors and Tasting Flavors: distinguishing orthonasal smell from retronasal olfaction1
TLDR
The account of orthonasal smell developed in the Molecular Structure Theory of smell can be expanded for retronasal olfaction to ensure that the perceptible objects the authors refer to as smells and individuated on the basis of their olfactory qualities are only relative to orthonAsal Olfaction.
Variability in Retronasal Odor Identification Among Patients With Chronic Rhinosinusitis
TLDR
Understanding preserved retronasal neural stimuli may allow providers to improve eating-related quality of life in patients with chronic rhinosinusitis; however, patients with anosmia can still identify certain retron asal odors more often than expected.
Olfactory Development, Part 1: Function, From Fetal Perception to Adult Wine-Tasting
TLDR
Diverse malformations of the olfactory bulb can be diagnosed by clinical examination, imaging, and neuropathology, especially in patients with brainmalformations, endocrinopathies, chromosomopathies and genetic/metabolic diseases.

Sniffing and smelling: separate subsystems in the human olfactory cortex
TLDR
It is found that sniffing, whether odorant is present or absent, induces activation primarily in the piriform cortex of the temporal lobe and in the medial and posterior orbito-frontal gyri of the frontal lobe.
Inspiratory phase‐locked alpha oscillation in human olfaction: source generators estimated by a dipole tracing method
TLDR
It is suggested that the inspiratory phase‐locked alpha oscillation (I‐α) in this study originated from the olfactory cortex in the forebrain and was phase‐lock to inspiration.
Gustatory Neural Responses in the Medial Orbitofrontal Cortex of the Old World Monkey
TLDR
An area centered in Brodmann's area 13m of the medial OFC (mOFC) where taste neurons are more concentrated appears to comprise a major gustatory relay that lies anatomically and functionally between the anterior insula and the clOFC.
Changes in brain activity related to eating chocolate: from pleasure to aversion.
TLDR
The hypothesis that there are two separate motivational systems: one orchestrating approach and another avoidance behaviours is supported, suggesting that the reward value of food is represented here.

TLDR
Olfactory neurons in the primate orbitofrontal cortex decrease their responses to a food eaten to satiety, but remain responsive to other foods, thus contributing to a mechanism for olfactory sensory-specific satiety.

TLDR
It is suggested that the orbitofrontal cortex may act as a region for convergence of multiple sensory modalities including chemosensation, and may be the first cortical area of convergence for these three modalities in primates.
