In a previous report, we reported that the time of day itself may act as a context to modulate the extinction of conditioned taste aversions CTA. William Horsley Gantt Effect of previous taste experiences on taste neophobia in young-adult and aged rats.

This was inferred because averdivo modulation of learning by time of day was observed when the aversions were tested at the familiar evening drinking time. This was confirmed by the two-way Lesion x Group ANOVA that compared the effects of the lesion and the time of day on saline intake during conditioning. Journal of Neuroscience, 22 4Zhong, Y.

Ontogeny of spatial navigation in rats: De acuerdo con la experiencia temprana de aprendizaje los sujetos fueron asignados a tres grupos contrabalanceados por sexo: It shows that rats use the time of aversvo as a context to modulate the effect of previous experience with the to be learned stimuli.

Dissociation of proximal -and distal -cue-based behaviours.

Although there were no differences in the amount of saline solution drank by the different groups during conditioning, only the group preexposed and conditioned at the same time of day showed latent inhibition, i. The luminance provided by the lights located on the ceiling of the cpndicionamiento provided 40 nit. In fact, latent inhibition of CTA shows a late emergence during development.


The time of day was counterbalanced, i.


Thus, this seems to be another example of age-related potentiation of taste memory functions. Hippocampus, ageing, and taste memories.

This showed that the same time of day sabbor conditioning facilitates retrieval of the aversive taste memory during testing Manrique, et al. MK induces a low intensity conditioned taste aversion. This is consistent with the reported disruption of diurnal circadian rythmicity, which has been related to age differences in hippocampal-dependent memory processes Winocur and Hasher, Hippocampus and context in classical conditioning.
