Olfactory stimulation was provided to the subjects with different aromatic air samples with a 5-second rest period, followed by a 20-second olfactory stimulus period. It was concluded that the odor of lemon, traditionally thought to be stimulative, had the effect of activating anticipation or attention process.
A fragrance wheel also known as aroma wheel, fragrance circle, perfume wheel or smell wheel, is a circular diagram showing the inferred relationships among olfactory groups based upon similarities and differences in their odor. [1] The groups bordering one another are implied to share common olfactory characteristics.
The olfactory epithelium is a specialized epithelial tissue inside the nasal cavity that is involved in smell. In humans, it measures 5 cm 2 (0.78 sq in) [1] and lies on the roof of the nasal cavity about 7 cm (2.8 in) above and behind the nostrils. [2] The olfactory epithelium is the part of the olfactory system directly responsible for ...
The olfactory system, or sense of smell, is the sensory system used for olfaction (i.e., smelling). Olfaction is one of the special senses directly associated with specific organs.
The olfactory system is the pathway between the nose and the brain. The system detects smell by processing the tiny odor molecules that waft off of various objects, such as baking bread or a ...
The olfactory nerve zone is composed of preterminals and terminals of the olfactory nerve and is where the olfactory receptor cells make synapses on their targets. [2] The non-olfactory nerve zone is composed of the dendritic processes of intrinsic neurons and is where dendrodendritic interactions between intrinsic neurons occur. [2]
The three-layered olfactory cortex, containing pyramidal cells is the next benchmark on the smell pathway. One pyramidal cell receives information from a multiplicity of mitral cells from the olfactory bulb, making the previously organized glomerular pattern distributed in the olfactory cortex.
Researchers of this study note that the olfactory pathway from the neurons in the nose to the brain could allow certain substances into the brain. For this study, researchers examined the ...
