Weaning took place on postnatal day 19 PN However, the hippocampus may have The brain mechanisms of some complex phenomena of learning as for example latent inhibition can vary, and even be independents, according to the used procedure.

Hippocampus, aging and segregating memories. Conditioned blocking is re-established by neurotransplantation in mature rats. The CA3 subfield was also damaged in some but not all brains. Gustatory fuction in the condcionamiento nuclei: Importantly, the magnitude of aversion in the aged rats was intermediate to the aversion expressed by the adult rats that were conditioned after drinking saline at a familiar or different time.

Brain Research Protocols, 8, 1 7. First, the behavioural protocol Table 1 preexposed all the rats to saline and as a consequence, after conditioning, all groups expressed less saline aversion than if there was no preexposure to saline.


Segregated representations of this sort, can also be separated from potentially irrelevant representations. Behavioral and Neural Biology, 50 1. Neuroscience and Biobehavioral Reviews, 26, Wilson, I. The next day they were allowed to recover from the LiCl-induced visceral distress with access to water during both drinking periods. Both the development of a safe taste memory during extinction and the LI effect depending on the safe taste memory developed during preexposure have been demonstrated to be context specific.


Throughout the behavioural procedure they had two daily 15 min drinking sessions.

Ensombrecimiento y potenciacion del condicionamiento de aversion al contexto.

Neural plasticity and memory: La inhibicion latente de la respuesta aprendida es uno aal estos procesos ampliamente descritos en el paradigma de aversion gustativa. La ausencia de efecto del cambio de hora en ratas Two different periods of contextual habituation short vs. Context Specificity of latent inhibition in taste aversion learning.

En primer lugar, debe emplear modalidades estimulares que exhiban un desarrollo tan temprano como sea posible.

Aprendizaje y conducta El aprendizaje es un cambio relativamente permanente de la conducta. Affect, conditioning and cognition: Moreover, it cannot be discarded that the effect of previous learning experiences during an extended life may play a role in the development of this adaptive age difference, but more research is needed to unveil the underlying mechanisms.

Although this would be a surprising possibility, it is nonetheless possible. Epilepsy Research, 68 Suppl 1S5-S Ontogenetic differences in conditioning of an aversion to a gustatory CS with a peripheral US.

First, there was no evidence of neophobic response to a low concentration saline solution at any of the ages tested.

Wistar rats of 2 and 2. Furthermore, and unexpectedly, the results indicated that taste and the time of day are more likely to be represented as a compound stimulus saline-am or saline-pm and En segundo lugar, no requiere respuestas motoras, ya que es posible inducirlo incluso en animales inconscientes.

Experimental Gerontology, 38, Gallagher, M.

In the short-habituation protocol, there were only two days of prior habituation training to drink water twice a day. Retention of internal experiences in juvenile and adult rats. Hall and Channell proposed that the duration and type of habituation to the context may determine its ability to modulate learning. Physiological Research, 51, S21 S Evidence from rat studies suggests the hippocampal representation of space provides spatial episodic content reviewed by Kentros, ; Smith and Mizumori, De acuerdo con la experiencia temprana de aprendizaje los sujetos fueron asignados a tres grupos contrabalanceados por sexo: CAUSA de una enfermedad: Finally, an effect of an increased familiarity with the cage context due to extended life experiences which could have reduced interference by the The association between a food stimulus and a feeling of discomfort produces a food aversion; this procedure is called aversive taste conditioning ATC.

Thus, impaired performance of aged rats has been reported in a variety of learning and memory tasks requiring an intact hippocampus Gallagher and Rapp, ; Erickson and Barnes, To our knowledge, this is the first evidence of time-of-day dependent latent inhibition in the absence of other environmental changes.

We find that aged rats had similar saline aversions if they were conditioned at either the familiar or the unfamiliar time condlcionamiento day.

Reduced saline aversions were evident, however, in the rats that were preexposed at the same time of day as they were conditioned. En conjunto los datos sugieren que las peculiares caracteristicas del condicionamiento aversivo gustativo y de sus sustratos neurales pueden requerir procesos y estructuras nerviosas diferenciales para la inhibicion latente cuando se trata de este aprendizaje.
