  2. Gustatory cortex - Wikipedia

    en.wikipedia.org/wiki/Gustatory_cortex

    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]

  3. Taste - Wikipedia

    en.wikipedia.org/wiki/Taste

    The diagram depicts the signal transduction pathway of the sour or salty taste. Object A is a taste bud, object B is a taste receptor cell within object A, and object C is the neuron attached to object B. I. Part I is the reception of hydrogen ions or sodium ions. 1. If the taste is sour, H + ions, from acidic substances, pass through H ...

  4. Gustatory nucleus - Wikipedia

    en.wikipedia.org/wiki/Gustatory_nucleus

    In both humans and rats, taste sensitivity changes with body weight, especially sweet and fat taste qualities that signal high energy availability. The nucleus tractus solitarii (NTS), which includes the gustatory nucleus, has neurons that express many different receptors that inform organisms of their internal state and are involved in the ...

  5. Sensory nervous system - Wikipedia

    en.wikipedia.org/wiki/Sensory_nervous_system

    A sensory system consists of sensory neurons (including the sensory receptor cells), neural pathways, and parts of the brain involved in sensory perception and interoception. Commonly recognized sensory systems are those for vision, hearing, touch, taste, smell, balance and visceral sensation.

  6. Taste receptor - Wikipedia

    en.wikipedia.org/wiki/Taste_receptor

    The diagram above depicts the signal transduction pathway of the sweet taste. Object A is a taste bud, object B is one taste cell of the taste bud, and object C is the neuron attached to the taste cell. I. Part I shows the reception of a molecule. 1. Sugar, the first messenger, binds to a protein receptor on the cell membrane. II.

  7. Solitary nucleus - Wikipedia

    en.wikipedia.org/wiki/Solitary_nucleus

    The solitary nucleus receives general visceral and special visceral inputs from the facial nerve (CN VII), glossopharyngeal nerve (CN IX) and vagus nerve (CN X); it receives and relays stimuli related to taste and visceral sensation. It sends outputs to various parts of the brain, such as the hypothalamus, thalamus, and reticular formation ...

  8. Sense of smell - Wikipedia

    en.wikipedia.org/wiki/Sense_of_smell

    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.

  9. Primary sensory areas - Wikipedia

    en.wikipedia.org/wiki/Primary_sensory_areas

    Taste: The primary gustatory area consists of the anterior part of the insula and the frontal operculum. [2] [3] [4] Olfaction: The olfactory cortex is located in the uncus which is found along the ventral surface of the temporal lobe. Olfaction is the only sensory system that is not routed through the thalamus.
