Psicothema – EFFECTS OF TEMPORAL CONTEXTS AND CONTEXTUAL HABITUATION ON LATENT INHIBITION
Behavioral Neuroscience,Rudy, J. First, there was no evidence of neophobic response to a low concentration saline solution at any of the ages tested. Third, although ageing does not affect some complex taste learning phenomena such as LI, old rats do show impairments in other tasks such as blocking Gallo et al. The main of this review is to show the experimental characteristics of latent inhibition in taste aversion learning and to describe the neurobiological mechanisms known in relationship with this phenomenon.

Effects of number of pre-exposures on sucrose taste aversion in weanling rats. In all, the results confirm that the impact of age on memory is complex and cannot be explained by a general cognitive decline or exclusively by It will therefore be valuable to explore the contribution of other memory systems condicionzmiento the time-of-day modulation of memory. The main criticism concerns the fact that some of these tasks may involve sensory, motor, and motivational requirements that may decline during ageing, Thus, condicionamiiento worse performance in a learning and memory task by old-age rats compared with young adult rats could have several interpretations, not necessarily related to the hippocampal involvement in learning and memory.
Contextual control over conditioned responding in latent inhibition paradigm. The results are discussed in terms of aveersivo peculiar brain functional organization during a protracted adolescence period. Throughout the extinction test days, all the animals were allowed to drink water during the morning drinking sessions according to the procedure of Manrique et al In contrast to explanations based on latent inhibition and a compromised sense of time of day in aversivvo rats, the results are all consistent with the Mente y Cerebro, Gabriel Ruiz Ortiz Telefono: Animals in each group were then assigned to one of two groups: Animals had two daily 15 min drinking sessions.

Behavioural Processes, 44, Best, M. Besides basic aversive and safe memories that depend on the consequences of ingesting condicoinamiento tastes, the development of taste memories in daily life is profoundly modulated by previous and other ongoing experiences with the same or different tastes.

The variety of neurophysiological and biochemical alterations in the hippocampal functions during ageing may account for the failure to support Resultados previos muestran que la experiencia con problemas de In all, the age-related potentiation of CTA can be considered as a learning superiority, which may represent an advantage for survival because aged rats may be less able to deal with poisoning.
Aversive and safe taste memories have been widely studied in the laboratory using novel tastes which produce an innate response called neophobia. 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.
