Description
Summary:The spatial properties of the tongue play an important role in taste phenomena observed in the clinic. Using a spatial screening test that compares six loci (the right and left sides of the front and rear edges of the tongue and the right and left sides of the palate), the authors have found localized losses of taste function in two etiological groups: head trauma and upper respiratory infection. Even patients with losses over extensive areas of the oral cavity can be unaware of the loss. They may also appear to be nearly normal on a conventional, whole mouth, sip and spit taste test. This occurs because relatively small areas of normal tissue can produce very intense sensations and the location of the taste sensations is not salient to the patient.
