For the nocturnal hawkmoth Manduca sexta , olfactory and gustatory cues are essential for finding partners, food, oviposition sites. Three chemosensory receptor families, odorant receptors (ORs), ionotropic (IRs), (GRs) involved in detection of these stimuli. While many genes have been identified, knowledge their expression profile potentially chemoreceptive organs is incomplete. Here, we studi...

BACKGROUND Gustatory sweating, the main symptom of Frey's syndrome, usually occurs after parotid gland surgery. Numerous medical and surgical treatments have been proposed to treat this condition, but there are various drawbacks. Botulinum toxin type A intracutaneous injection is a relatively new treatment modality; its use has never been reported in Taiwan. Here, we present our preliminary exp...

In tactile learning, sucrose is the unconditioned stimulus and reward, which is usually applied to the antenna to elicit proboscis extension and which the bee can drink when it is subsequently applied to the extended proboscis. The conditioned stimulus is a tactile object that the bee can scan with its antennae. In this paper we describe the quantitative relationships between gustatory antennal...

Salmonids are a group of teleosts with a nonspecialized gustatory system. With the aim of describing the gustatory connections in a member of this group, we carried out tract-tracing experiments using the lipophilic carbocyanine dye 1,1'-dioctadecyl 3,3,3',3'-tetramethylindocarbocyanine perchlorate (DiI) in fixed brains of the rainbow trout (Oncorhynchus mykiss). The neural tracer was applied t...

If for no other reason than the fact that eating and drinking gives us pleasure, it is of interest to understand the physiology of gustation. In this issue, Lyall et al. (2002a) have uncovered the key cellular mechanisms that occur in taste receptor cells (TRCs) when certain mixtures of chemicals (tastants) are applied to the anterior tongue. In much the same way as music produced by a quartet ...
