Summary
Odor hedonic perception, the pleasantness of smells, varies greatly due to stimulus, individual, and context factors. This review details these influences on olfactory perception and behavior.
Area of Science:
- Neuroscience
- Sensory Science
- Psychology
Background:
- Odor hedonic perception is a primary dimension of olfaction.
- It is highly variable, influenced by multiple factors.
- A comprehensive review on this variability is lacking.
Purpose of the Study:
- To comprehensively review factors influencing odor hedonic perception variability.
- To detail stimulus, individual, and context-related influences.
- To explore brain processing and behavioral links.
Main Methods:
- Literature review and synthesis.
- Categorization of variability factors.
- Discussion of neurobiological and behavioral aspects.
Main Results:
- Identified stimulus properties (concentration, physicochemical traits) as key factors.
- Detailed individual differences (sex, age, physiological state).
- Highlighted contextual influences (pathway, exposure, verbal cues, cross-modal, contrast, culture).
Conclusions:
- Odor hedonic perception variability is multifactorial.
- Stimulus, individual, and context significantly shape olfactory pleasantness.
- Further research is needed on brain processing and behavioral outcomes.

The sense of smell is achieved through the activities of the olfactory system. It starts when an airborne odorant enters the nasal cavity and reaches olfactory epithelium (OE). The OE is protected by a thin layer of mucus, which also serves the purpose of dissolving more complex compounds into simpler chemical odorants. The size of the OE and the density of sensory neurons varies among species; in humans, the OE is only about 9-10 cm2.

Humans detect odors with the help of specialized cells located in the upper part of the nasal cavity, called olfactory receptor neurons (ORNs). ORNs possess hair-like structures called cilia, which are receptive to sensations from the inhaled air. When an odorant molecule binds to a specific receptor on the cell of the cilia, it leads to a series of events that ultimately cause the ORN to send electrical signals to the olfactory bulb in the brain through the olfactory nerves.

Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...

9.2K
The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...

Gustation is a chemical sense that, along with olfaction (smell), contributes to our perception of taste. It starts with the activation of receptors by chemical compounds (tastants) dissolved in the saliva. The saliva and filiform papillae on the tongue distribute the tastants and increase their exposure to the taste receptors.
