Abstract

Estudos experimentais identificaram células piramidais no hipocampo de ratos com participação na memória de orientação espacial (MOE), denominadas células de localização. O objetivo deste estudo foi adaptar um teste baseado nesses experimentos para verificar o desempenho de MOE e a participação do hipocampo na MOE em pacientes com esclerose mesial temporal (EMT). Dividiu-se a pesquisa em dois estudos: no primeiro adaptou-se o teste e visando verificar sua capacidade de investigação de déficits de MOE aplicou-se em grupos de 10 indivíduos, um com doença de Alzheimer (DA) e outro de idosos saudáveis (pExperimental studies have identified pyramidal cells in hippocampus in rats with participation in the spatial orientation memory (SOM), which are named location cells. This study had the purpose to adapt a test based in these experiments in order to check the performance of SOM and the participation of hippocampus into SOM in patients with mesial temporal sclerosis (MTS). The research was divided into two studies: the first one the test was adapted, and in order to check its capacity to investigate the deficits of SOM, it has applied in groups of 10 (ten) subjects, one group with patients that have Alzheimer disease and the other one with healthy elderly (p
