Effects of pre- or post-training entorhinal cortex AP5 injection on fear conditioning
(Elsevier B.V., 2005-11-15)
Fear conditioning is one of the most studied paradigms to assess the neural basis of emotional memory. the circuitry involves NNMA receptor activation in the amygdala and, in the case of contextual conditioning, in the ...
The indirect amygdala-dorsal striatum pathway mediates conditioned freezing: Insights on emotional memory networks
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
The dorsal striatum (DS) is involved in various forms of learning and memory such as procedural learning, habit learning, reward-association and emotional learning. We have previously reported that bilateral DS lesions ...
Classical tone-shock conditioning induces Zenk expression in the pigeon (Columba livia) hippocampus
(Amer Psychological Assoc/educational Publishing FoundationWashingtonEUA, 2006)
Induction of Zenk protein expression within the nucleus taeniae of the amygdala of pigeons following tone and shock stimulation
(Associação Brasileira de Divulgação Científica, 2011)
In this study, we evaluated the expression of the Zenk protein within the nucleus taeniae of the pigeon’s amygdala (TnA) after training in a classical aversive conditioning, in order to improve our understanding of ...
Chronic stress induces dendritic atrophy in the rat medial geniculate nucleus: Effects on auditory conditioning
(ELSEVIER, 2009)
Chronic stress induces dendritic atrophy in the inferior colliculus (IC, auditory mesencephalon) and impairs auditory avoidance conditioning. The aim of this study was to determine in Golgi preparations and in cued fear ...
The indirect amygdala-dorsal striatum pathway mediates conditioned freezing: Insights on emotional memory networks
(Elsevier B.V., 2008-04-22)
The dorsal striatum (DS) is involved in various forms of learning and memory such as procedural learning, habit learning, reward-association and emotional learning. We have previously reported that bilateral DS lesions ...
Effects of nociceptin/orphanin FQ in the acquisition of contextual and tone fear conditioning in rats
(Amer Psychological Assoc, 2008-02-01)
Nociceptin, or orphanin FQ (N/OFQ), the endogenous ligand of NOP receptors, is known to regulate learning and memory processes. To verify the role of N/OFQ in the acquisition of contextual (CFC) and tone fear conditioning ...
Interaction between glutamatergic-NMDA and cholinergic-muscarinic systems in classical fear conditioning
(Elsevier B.V., 2008-09-30)
A number of studies have suggested that the glutamatergic and cholinergic systems are both involved in learning and memory processes and that they interact in order to facilitate these processes. However, the role of ...
Pre-test metyrapone impairs memory recall in fear conditioning tasks: lack of interaction with I--adrenergic activity
(Frontiers Research Foundation, 2015-03-03)
Cognitive processes, such as learning and memory, are essential for our adaptation to environmental changes and consequently for survival. Numerous studies indicate that hormones secreted during stressful situations, such ...
Efeitos da desconexão funcional entre o estriado dorsal e a amígdala nas tarefas de condicionamento clássico de medo ao som e ao contexto
(Universidade Federal de São Paulo (UNIFESP), 2008-01-30)
The central nucleus of the amygdala (CeA) - a critical structure in emotional memory - projects to the substantia nigra pars compacta and retrorubral nucleus, both of which provide dopaminergic innervation to the dorsal ...
