Nosework, also known as scent work or scent detection, is a dog sport created to emulate tasks performed by professional detection dog. In the sport, one dog and one handler form a team where the dog must find a hidden target odor , often ignoring distractions such as food or toys, and alert the handler once the target odor is found.
Written between 1835 and 1836, "The Nose" tells the story of a St. Petersburg official whose nose leaves his face and develops a life of its own. "The Nose" was originally published in The Contemporary, a literary journal owned by Alexander Pushkin. [2] The use of a nose as the main source of conflict in the story could have been due to Gogol's ...
How sounds make their way from the source to the human brain. An ear is the organ that enables hearing and (in mammals) body balance using the vestibular system. In mammals, the ear is usually described as having three parts: the outer ear, the middle ear and the inner ear. The outer ear consists of the pinna and the ear canal.
This suggests an innate component of odorant pleasantness that is tightly linked to molecular structure [1] An electronic nose is an electronic sensing device intended to detect odors or flavors. The expression "electronic sensing" refers to the capability of reproducing human senses using sensor arrays and pattern recognition systems.
Olfactory receptors ( ORs ), also known as odorant receptors, are chemoreceptors expressed in the cell membranes of olfactory receptor neurons and are responsible for the detection of odorants (for example, compounds that have an odor) which give rise to the sense of smell. Activated olfactory receptors trigger nerve impulses which transmit ...
The human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion (the tongue, salivary glands, pancreas, liver, and gallbladder ). Digestion involves the breakdown of food into smaller and smaller components, until they can be absorbed and assimilated into the body. The process of digestion has three ...
Odor detection value. Odor threshold value (OTV) (also aroma threshold value (ATV), Flavor threshold) is defined as the most minimal concentration of a substance that can be detected by a human nose. Some substances can be detected when their concentration is only few milligrams per 1000 tonnes, which is less than a drop in an Olympic swimming ...
The diving reflex, also known as the diving response and mammalian diving reflex, is a set of physiological responses to immersion that overrides the basic homeostatic reflexes, and is found in all air-breathing vertebrates studied to date. [1] [2] [3] It optimizes respiration by preferentially distributing oxygen stores to the heart and brain ...
