Machine olfaction is the automated simulation of the sense of smell. An emerging application in modern engineering, it involves the use of robots or other automated systems to analyze air-borne chemicals. Such an apparatus is often called an electronic nose or e-nose.
In a single sniff, the human sense of smell can distinguish odors within a fraction of a second, working at a level of sensitivity that is “on par” with how our brains perceive color ...
The olfactory bulb transmits smell information from the nose to the brain, and is thus necessary for a proper sense of smell. As a neural circuit, the glomerular layer receives direct input from afferent nerves, made up of the axons from approximately ten million olfactory receptor neurons in the olfactory mucosa, a region of the nasal cavity.
Olfactic communication is a channel of nonverbal communication referring to the various ways people and animals communicate and engage in social interaction through their sense of smell. Our human olfactory sense is one of the most phylogenetically primitive [1] and emotionally intimate [2] of the five senses; the sensation of smell is thought ...
The role of smell has long been viewed as secondary to the importance of auditory, tactile, and visual senses. [23] Humans do not rely on olfaction for survival to the same extent as other species. Instead, smell plays a heavier role in aesthetic food perception and gathering information on the surroundings. [1]
The olfactory system, is the sensory system used for the sense of smell (olfaction). Olfaction is one of the special senses directly associated with specific organs. Most mammals and reptiles have a main olfactory system and an accessory olfactory system. The main olfactory system detects airborne substances, while the accessory system senses ...
Stimuli transmitted to the limbic system cannot be consciously blocked, so all olfactory stimuli influence our emotions. [10] Smell has not been studied in as much depth as vision and hearing. The brain is able to process small differences in smell and the sense of smell may last longer in the aging process than sight and hearing. [11]
A terrifying escalator accident caught on camera at Repubblica metro station in Rome, Italy, injured about two dozen people on Tuesday. Horrifying video shows crowded escalator speed out of ...
