Thus, the sensory modalities will be visual, auditory, tactile, olfactory, gustatory, kinesthetic, etc. Signs can communicate through any of the senses, visual, auditory, tactile, olfactory, or gustatory. These receptors are gustatory and olfactory (related to taste and smell). Thalamocortical radiations also innervate gustatory and olfactory pathways, as well as pre-frontal motor areas. Electrical stimulation of the insula in the human elicit gustatory sensations. Underwater food detection is presumably gustatory and tactile. The ventromedial basal nucleus (VMb) receives parasympathetic information from visceral and gustatory systems. The anterior insula is part of the primary gustatory cortex. The gustatory cortex is the primary receptive area for taste. The cortical region related to gustatory sensation is located anterior to the central sulcus. The gustatory cortex is responsible for the perception of taste. Taste buds contain the taste receptor cells, which are also known as gustatory cells. A G protein signal transduction system ultimately leads to depolarization of the gustatory cell. Taste sensation is sent to the gustatory portion (superior part) of the solitary nucleus. Information is then passed from here through the thalamus into the gustatory cortex.
