A link between the hippocampal and the striatal memory systems of the brain

Anais da Academia Brasileira de Ciências, 2006
Two major memory systems have been recognized over the years (Squire 1987): the declarative memory system, which is under the control of the hippocampus and related temporal lobe structures, and the procedural or habit memory system, which is under the ...

The evidence for hippocampal long-term potentiation as a basis of memory for simple tasks

Anais da Academia Brasileira de Ciências, 2008
Long-term potentiation (LTP) is the enhancement of postsynaptic responses for hours, days or weeks following the brief repetitive afferent stimulation of presynaptic afferents.

The pilocarpine model of epilepsy: what have we learned?

Anais da Academia Brasileira de Ciências, 2009
The systemic administration of a potent muscarinic agonist pilocarpine in rats promotes sequential behavioral and electrographic changes that can be divided into 3 distinct periods: (a) an acute period that built up progressively into a limbic status ...

Aquisição de uma tarefa temporal (DRL) por ratos submetidos a lesão seletiva do giro denteado The acquisition of a temporal task (DRL) by dentate gyrus-selective colchicine lesioned rats

Psicologia: Reflexão e Crítica, 2006
A lesão seletiva do giro denteado (DG) reduz a eficiência do desempenho de ratos treinados pré-operatoriamente em um esquema de reforçamento diferencial de baixas taxas (DRL); embora os animais lesados sejam capazes de suprimir a resposta de pressão na ...
