An odorant is a physiochemical molecule that binds to a specific receptor protein. [1] In mammals, each olfactory receptor protein has one type of molecule that it responds to, known as the one-olfactory-one-neuron rule, and approximately one thousand kinds of which have been identified. [2]
Sensory information is stored in sensory memory just long enough to be transferred to short-term memory. [1] Humans have five traditional senses: sight, hearing, taste, smell, touch. Sensory memory (SM) allows individuals to retain impressions of sensory information after the original stimulus has ceased. [2]
The Lady and the Unicorn, a Flemish tapestry depicting the sense of smell, 1484–1500. Musée national du Moyen Âge, Paris..

Memory is one of the most crucial aspects of our health and human identity. Through memory, we create our individuality, our specific relationships with the world we inhabit, and we learn to stay ...
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] Nevertheless, humans also communicate via odorants and pheromones, exerting both subconscious and conscious (artificial) scents. [citation needed]
This multisensory integration was necessary for early humans in order to ensure that they were receiving proper nutrition from their food, and also to make sure that they were not consuming poisonous materials. [citation needed] There are several other sensory integrations that developed early on in the human evolutionary time line. The ...

The primary gustatory cortex (GC) is a brain structure responsible for the perception of taste.It consists of two substructures: the anterior insula on the insular lobe and the frontal operculum on the inferior frontal gyrus of the frontal lobe. [1]
