“…Thus, the extensive familiarization will turn the home cage into a safe context that will induce an increase in the consumption of any flavor presented in this context, regardless of the previous associative history of the flavor. De la Casa and Diaz (2012) provide evidence of this possibility by demonstrating that both neophobia habituation and flavor consumption after an episode of CTA were seen to increase when tests for consumption were conducted at home cages as compared to new or familiar experimental contexts.…”

“…Several possibilities arise here. In various paradigms, contextual change effects are reduced under contextual habituation prior to conditioning (De La Casa and Lubow, 2001;De la Casa et al, 2003;Lubow and De La Casa, 2005;Quintero et al, 2011;De la Casa and Díaz, 2013;Molero-Chamizo and Rivera-Urbina, 2017). Thus, the fluid restriction applied during the stages prior to conditioning might not affect the temporal specificity of LI if this restriction makes the temporal context more salient.…”

Temporal specificity of latent inhibition of conditioned taste aversion (CTA) has been demonstrated after prolonged habituation to temporal contexts in the stages preceding conditioning, and it has been eliminated by restricting consumption during conditioning. However, it is not known if latent inhibition of CTA is still dependent on the temporal context when fluid consumption is limited in the stages prior to conditioning. We tested temporal specificity of latent inhibition in rats with (different time of day for the conditioning stage) and without (same time of day for pre-exposure and conditioning stages) temporal changes on the conditioning day. All animals had limited access to water in the morning sessions of the stages prior to the conditioning day and 15 min of free access to fluid in the evening sessions of these stages. Compared to animals without temporal changes between stages, animals with a different temporal context during conditioning did not show evidence of latent inhibition. Unlike the effects observed after taste stimulus restrictions during conditioning, these results suggest that the temporal specificity of latent inhibition of CTA is not abolished when access to water is limited in the stages preceding conditioning.

“…To our knowledge, there is only one previous report using an auditory background as part of the context in taste learning (Bonardi et al, 1990). Most previous research used visual cues (Quintero et al, 2011; De la Casa and Díaz, 2013), as well as temporal information to define context (Moron et al, 2002; De la Casa et al, 2003; Manrique et al, 2004).…”

“…These same stimuli can of course also become foreground conditioned stimuli, depending on the task (Nadel and Willner, 1980; De la Casa et al, 2018). The study of context in different taste recognition memory tasks has primarily investigated spatial contexts, often defined only by visual cues (Quintero et al, 2011; De la Casa and Díaz, 2013), as well as temporal contexts, defined either as time elapsed (De la Casa et al, 2003) or the time of day (Moron et al, 2002; Manrique et al, 2004). In this context, it is important that memory, spatial and temporal task information are signaled in the discharge of hippocampus CA1 cells, as well as other hippocampus subfields (Lenck-Santini et al, 2008; Pastalkova et al, 2008; Jezek et al, 2011; Eichenbaum, 2017; van Dijk and Fenton, 2018).…”

Rodents exhibit neophobia for novel tastes, demonstrated by an initial reluctance to drink novel-tasting, potentially-aversive solutions. Taste neophobia attenuates across days if the solution is not aversive, demonstrated by increased consumption as the solution becomes familiar. This attenuation of taste neophobia is context dependent, which has been demonstrated by maintained reluctance to drink the novel tasting solution if the subject has to drink it after being brought to a novel environment. This spatial context-dependent attenuation of taste neophobia has been described and likely depends on the integrity of the dorsal hippocampus because this brain area is crucial for representing space and spatial context associations, but is unnecessary for processing taste memories per se. Whether changing the non-spatial auditory context causes a similar effect on attenuation of taste neophobia and the potential role of the dorsal hippocampus in processing this decidedly non-spatial information has not been determined. Here we demonstrate that changing the non-spatial auditory context affects the attenuation of taste neophobia in mice, and investigate the consequence of hippocampal lesion. The results demonstrate that the non-spatial auditory context-dependent attenuation of taste neophobia in mice is lost following NMDA excitotoxic lesions of the CA1 region of the dorsal hippocampus. These findings demonstrate that the dorsal hippocampus is crucial for the modulation non-associative taste learning by auditory context, neither of which provide information about space.

Contextual control of flavor neophobia

Abstract: The role of context in the retrieval of learned information has been widely analyzed in the associative learning domain. However, evidence about the effect of context on flavor memory retrieval is more limited. We have carried out
