Olfaction is a very important aspect in sexual reproduction throughout evolution because it triggers mating behaviour in many species. [26] Pheromones as olfactory chemical signals allow for members of the same species to perceive when other members are ready for reproduction. [27]
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.. Early scientific study of the sense of smell includes the extensive doctoral dissertation of Eleanor Gamble, published in 1898, which compared olfactory to other stimulus modalities, and implied that smell had a lower intensity discrimination.
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]

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]
GLP-1 drugs like Ozempic and Wegovy may affect your sense of taste and the way your brain responds to sweet foods.
The neocortex is greatly enlarged in humans and plays a central role for the cognitive abilities that make us human: language, imagination, memory, emotion, etc.” — Franz Xaver Mittermaier
