2015, Progress in NeurobiologyCitation Excerpt :Rats with conditioned aversions to 1.0 M glucose show decreasing acceptance of glucose solutions as their concentrations approach 1.0 M. This acceptance gradient can be compared between euglycemic rats and those made hyperglycemic through intravenous injections (Scott and Giza, 1987). Hyperglycemic rats showed greater acceptance at all concentrations from 0.6 to 2.0 M glucose, indicating that they perceived these stimuli to be less intense than did conditioned rats with no glucose load (Giza and Scott, 1987a).
Chronic dietary magnesium-L-threonate speeds extinction and reduces spontaneous recovery of a conditioned taste aversion
2013, Pharmacology Biochemistry and BehaviorCitation Excerpt :Second, if training is sufficiently extensive and animals are given repeated experiences with 2 gustatory stimuli that are quite similar in taste, they may be able to learn to differentiate between them if one is continued to be reinforced while the other is not. In fact, extremely small differences in concentrations (e.g., 2.4 × 10- 6 M) of the same compound (HCl) can be detected when similar taste discrimination methodologies are employed (Scott and Giza, 1987). In order to interpret our findings as being consistent with MgT-induced enhancement of memory, it is important to confirm that SAC only and SAC + MgT are similar enough so that, in the context of our study, rats were unlikely to detect/recognize subtle taste differences between the 2 stimuli during extinction and our SR test.
Lesions of the central nucleus of the amygdala decrease taste threshold for sodium chloride in rats
2012, Brain Research BulletinCitation Excerpt :The method employed in determining the taste threshold for NaCl solutions involves conditioning animals to avoid a suprathreshold concentration of sodium chloride solution used as a CS. If the conditioned groups are tested with a series of concentrations of sodium chloride, they will avoid the concentrations of NaCl solutions within a certain range identified as the CS (Clarke et al., 2001; du Villard et al., 1981; Ishiwatari and Bachmanov, 2009; Lu et al., 2009a; Ramirez, 1991; Scott and Giza, 1987; Tapper and Halpern, 1968; Yamamoto et al., 1994). Since the approach is based on conditioning a response to a single stimulus concentration and measuring responses to other concentrations, it could strictly be classified as an ‘intensity generalization threshold’ rather than a ‘taste recognition threshold’.
Interactions of temperature and taste in conditioned aversions
2010, Physiology and BehaviorCitation Excerpt :When given a 2-bottle choice between the conditioned thermal cue and a cue of a different temperature, rats would be more motivated to avoid the conditioned cue and consume the “safe” cue, thus demonstrating discrimination. A lack of avoidance under these conditions would more precisely define an inability to discriminate [16,17]. Conversely, generalization behavior can also be shown with a conditioned aversion paradigm.
Constructing quality profiles for taste compounds in rats: A novel paradigm
2008, Physiology and BehaviorCitation Excerpt :This refers to the documented tendency of animals to display increased responses to stimuli that have higher intensity than the training stimulus and decreased responses to stimuli that have a lower intensity. Interactions between intensity of the CS and the test stimulus (TS) have been reported to influence the magnitude of avoidance displayed after taste aversion conditioning [11–13]. Finally, given that testing occurs in extinction, the number of test stimuli and test sessions possible is restricted.
