| gustatory hallucination | The sensation of taste in the absence of a gustatory stimulus; may be seen in temporal lobe epilepsy. (05 Mar 2000) |
|---|---|
| gustatory hyperesthesia | Abnormal acuteness of the sense of taste. Synonym: gustatory hyperesthesia, oxygeusia. Origin: hyper-+ G. Geusis, taste (05 Mar 2000) |
| gustatory lemniscus | The uncrossed secondary-sensory fibre system ascending from the rhombencephalic gustatory nucleus to the parabrachial nuclei (rostral pontine level) and directly to the thalamic gustatory nucleus (ventral postero-medial nucleus, pars parvicellularis). (05 Mar 2000) |
| gustatory nucleus | See: rhombencephalic gustatory nucleus, thalamic gustatory nucleus. (05 Mar 2000) |
| gustatory organ | Located in the papillae of the mucous membrane of the tongue, chiefly in the vallate papillae. Synonym: organum gustus, organ of taste. (05 Mar 2000) |
| gustatory pore | The minute opening of a taste bud on the surface of the oral mucosa through which the gustatory hairs of the specialised neuroepithelial gustatory cells project. Synonym: porus gustatorius, taste pore. (05 Mar 2000) |
| gustatory rhinorrhoea | Watery nasal discharge associated with stimulation of the sense of taste. (05 Mar 2000) |
| gustatory-sudorific reflex | Sweating, especially over the face, when chewing food. See: auriculotemporal nerve syndrome. (05 Mar 2000) |
| gustatory sweating syndrome | <syndrome> Localised flushing and sweating of the ear and cheek in response to eating. Synonym: Frey's syndrome, gustatory sweating syndrome. (05 Mar 2000) |
| sweating, gustatory | Excessive sweating of the forehead, upper lip, perioral region, or sternum subsequent to ingestion of hot or spicy foods. It may also be caused by tumours or other injuries to the parotid gland, as in auriculotemporal syndrome (frey's disease). In this condition, thought to be due to some involvement of the auriculotemporal nerve, a red area and sweating on the cheek appear in connection with eating. (12 Dec 1998) |
| thalamic gustatory nucleus | The small ventral region of the ventral posteromedial nucleus of thalamus in which the fibres of the gustatory lemniscus and secondary trigeminal tracts terminate; it projects to the lower part of the postcentral gyrus of the cerebral cortex. Synonym: arcuate nucleus, nucleus arcuatus thalami, nucleus arcuatus, semilunar nucleus of Flechsig, thalamic gustatory nucleus. (05 Mar 2000) |
| lacrimo-gustatory reflex | Chewing of food causing secretion of tears. See: crocodile tears syndrome. (05 Mar 2000) |
