“…For example, latent inhibition was reduced in a study in which external cues (and other variables such as the number of stimulus preexposures) were changed between preexposure and testing (De la Casa & Lubow, 2001), indicating that latent inhibition is sensitive to contextual changes in different stages of the experimental procedure. In the CTA paradigm, latent inhibition attenuation after an external context change between preexposure and conditioning/testing, but not between pre-exposure/conditioning and testing, also has been described (Quintero et al, 2011). Therefore, different contextual changes (both external and internal) applied in different stages of the behavioral procedure may affect the acquisition of latent inhibition (Hall & Channell, 1986;Quintero et al, 2014;Revillo et al, 2014).…”

Circadian-temporal context and latent inhibition of conditioned taste aversion: Effect of restriction in the intake of the conditioned taste stimulus

Latent inhibition of conditioned taste aversion (CTA) is sensitive to changes in the temporal context. A change in the time of day of conditioning with respect to the time of day of the preexposure can disrupt the latent inhibition. This contextual change in the time of day may reveal a temporal specificity of latent inhibition. The optimum procedure to induce this temporal specificity is not well established. For example, it has been shown that a long period of habituation to temporal contexts is one factor that can determine the effect. However, the experimental conditions on the conditioning day that facilitate this phenomenon are unknown. The aim of this study is to elucidate whether a restriction in the intake of the conditioned taste stimulus affects the temporal specificity of latent inhibition. Two main groups of Wistar rats were tested in a latent inhibition of CTA paradigm, in which the temporal specificity of this phenomenon was analyzed by a change in the time of day of conditioning. The intake of the taste stimulus was restricted in the conditioning day in one of the groups, but this restriction was not applied in the other group. The results indicated temporal specificity of latent inhibition only in the group without restriction, but not in the group with limitation in the intake of the taste stimulus during conditioning. These findings can help to elucidate the characteristics of the procedure to induce temporal specificity of latent inhibition.

“…Contexts shift has been used as a mechanism to abolish the LI, and all available data about this phenomenon point to hippocampal system and related areas as the neural substrate underlying this process (Honey and Good, 1993;Quintero et al, 2011a). For instance, Quintero et al (2011b) showed that changing the context between the preexposure and the conditioning stage substantially reduces LI with a conditioned taste aversion (CTA) procedure. In addition, this contextual specificity of LI was dependent of the ventral subiculum (Quintero et al, 2011a).…”

“…Thus, it has been reported that when using a conditioned taste aversion for reproducing the latent inhibition effect, the animals' home cages seem to have properties that make it easier to establish a safe memory trace of the flavor when it is not followed by relevant consequences [19,20].…”
