ERPs and contextual semantic discrimination: Degrees of congruence in wakefulness and sleep
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2006)
This study explores whether the brain can discriminate degrees of semantic congruency during wakefulness and sleep. Experiment 1 was conducted during wakefulness to test degrees of congruency by means of N400 amplitude. ...
Efeito do midazolam sobre a reconsolidação e a extinção da memória aversiva contextual em ratas
(2018)
Fêmeas apresentam particularidades no desempenho de tarefas hipocampo-dependentes, como é o caso da memória aversiva contextual. A memória reativada pode seguir destinos diferentes. A duração da sessão de reativação ...
Post-learning sleep transiently boosts context specific operant extinction memory
(Frontiers Research Foundation, 2017)
Operant extinction is learning to supress a previously rewarded behavior. It is known to
be strongly associated with the specific context in which it was acquired, which limits
the therapeutic use of operant extinction ...
Intermittent ethanol binge exposure impairs object recognition but spares contextual and tone fear memory in adolescent rats
(Pontificia Universidade Católica do Rio de JaneiroUniversidade de BrasíliaUniversidade de São Paulo, 2009-06-01)
Adolescent brain development seems to be important for the maturation of brain structures and behavior. Intermittent binge ethanol drinking is common among adolescents, and this type of drinking can induce brain damage and ...
Memory impairment induced by IL-1beta is reversed by alpha-MSH through central melanocortin-4 receptors
(Academic Press Inc Elsevier Science, 2009-12)
Interleukin-1beta (IL-1beta) significantly influences memory consolidation. Treatments that raise the level of IL-1beta in the brain, given after training, impair contextual fear conditioning. The melanocortin alpha-MSH ...
Hippocampal-Prefrontal cortex network dynamics predict performance during retrieval in a context-guided object memory task
(Cold Spring Harbour Laboratory, 2021-11)
Remembering life episodes is a complex process that requires the interaction between multiple brain areas. It is thought that contextual information provided by the hippocampus (HPC) can trigger the recall of a past event ...
Fear-context association during memory retrieval requires input from granular to dysgranular retrosplenial cortex
(Academic Press Inc Elsevier Science, 2019-09)
The contribution of the granular (area 29, A29) and dysgranular (area 30, A30) subdivisions of the retrosplenial cortex (RSC) to contextual fear memory (CFM) retrieval remains elusive. Here, intact and orchiectomized (ORC) ...
Dopamine in the dorsal hippocampus impairs the late-consolidation of cocaine-associated memory
(Nature Publishing Group, 2014-01)
Cocaine is thought to be addictive because it elevates dopamine levels in the striatum, reinforcing drug-seeking habits. Cocaine also elevates dopamine levels in the hippocampus, a structure involved in contextual conditioning ...
Contextual learning and context effects during infancy: 30years of controversial research revisited
(Pergamon-Elsevier Science Ltd, 2015-02)
Over the last 30. years a considerable number of reports have explored learning about context during infancy in both humans and rats. This research was stimulated by two different theoretical frameworks. The first, known ...
