Analytical issues in the evaluation of food deprivation and sucrose concentration effects on the microstructure of licking behavior in the rat.
Despite the lack of correlations between temporally contiguous burst and pause combinations, mean BS decreased and pause duration increased as meals progressed, implying that this microstructural parameter is influenced in part by taste.
A high-throughput screening procedure for identifying mice with aberrant taste and oromotor function.
An automated procedure that assesses taste responsiveness of individual mice to palatable and unpalatable taste stimuli and creates a normative database that could be used to assess taste function in the progeny of mutagenized (or genetically altered) mice.

It is suggested that changes in fat preference may contribute to long-term maintained weight loss after gastric bypass and the role of GLP-1 in mediating postprandial responses after Gastric bypass requires further investigation.
Taste reactivity as a dependent measure of the rapid formation of conditioned taste aversion: a tool for the neural analysis of taste-visceral associations.
Findings indicate that rats dramatically change their oromotor responses to sucrose during the period following LiCl administration, provided that the infusions start immediately after injection.
A quantitative comparison of taste reactivity behaviors to sucrose before and after lithium chloride pairings: a unidimensional account of palatability.
Overall, the array of response components could be projected onto a single unidimensional scale of palatability to capture the motivational states that ranged from acceptance to rejection.
Alterations of sucrose preference after Roux-en-Y gastric bypass
Rats Fail to Discriminate Quinine from Denatonium: Implications for the Neural Coding of Bitter-Tasting Compounds
The findings lend support to the hypothesis that there is only one qualitative type of bitterness, and highlight the need to confirm predictions about the downstream properties of the gustatory system, or any sensory system, based on upstream molecular and biophysical events.
The representation of taste quality in the mammalian nervous system.
In the peripheral gustatory system, the authors conclude that most qualities appear to be signaled by labeled lines; however, elements of both types of coding characterize signaling of sodium salts, suggesting that the central coding mechanism is less clear.

Giving that amiloride is tasteless to the rat, these results provide convincing evidence of the importance of narrowly tuned afferents in the discrimination between sodium and nonsodium salts and suggest that this is a general coding principle in the gustatory system.
The relative affective potency of glycine, L-serine and sucrose as assessed by a brief-access taste test in inbred strains of mice.
The affective potency of the stimuli tested here seems to be related to the ability of the compounds to bind with the T1R2+3 receptor complex, but the profile of strain responsiveness to these tastants in the brief-access test does not appear to be simply explained by the sweetener 'taster' status of the strain.
