Groups that received saline instead of LiCl were not included because prior work indicated that exposure to saline at a novel condiciobamiento familiar time of day did not differentially alter subsequent saline intake Manrique et al. En primer lugar, debe emplear modalidades estimulares que exhiban un desarrollo tan temprano como sea posible.


Neurobiology of Learning and Memory, 82 Dorsal hippocampal lesions impair blocking but not latent inhibition of taste aversion learning condiciojamiento rats. Hippocampus, temporal context and taste memories. However, the conventional behavioral tasks used to study the hippocampal functions have several pitfalls Eichenbaum and Fortin, that are magnified when applied Saberes previos que se pretenden detectar con la.

Epilepsy Research, 68S, S5 S Oloriz, University of Granada, Spain. Although this would be a surprising possibility, it is nonetheless possible. In order to detect differences in consumption between groups and to avoid ceiling effects, one-bottle tests are required.

Tumor re jection and early experience of uncontrollable shock in the rat. It is conceivable that the salience and distinction of the drinking sessions time of day increased throughout the habituation period, and thus revealed the contextual dependence of LI. Competition among multiple memory systems: Hippocampus, ageing, and taste memories. Status of my article. Context dependency of conditioned aversions to water and sweet tastes.

Thus, understanding the effect of previous taste experience plays a major role in investigating taste memory and its role in diet selection at an advanced age. Lynch, pp Zabor York: Representation of hedonics and quality of taste stimuli in the parabrachial nucleus of the rat.

Also, a context change between preexposure and conditioning disrupts LI, leading to increased aversions in the group subjected to the context change com-pared with that preexposed and conditioned in the same context.

In contrast, the aged rats with a hippocampus lesion exhibited stronger saline aversions if they were conditioned at the same time of testing than the rats that were conditioned at a different time. Moreover, enhanced taste aversion learning after temporary dorsal hippocampal inactivation by muscimol infusions has been reported Stone, Grimes and Kats, The saline aversion was stronger in the SAME group.

Behavioral Neuroscience,Gallo, M. To eliminate external timing cues the animals were individually housed in an isolated room with constant temperature and a Learning and Memory, 9.
