Efecto da estimulación eléctrica transcraneal sobre a aprendizaxe implícita

Abstract

[Resumo] Numerosos estudos indican que a aplicación de estimulación eléctrica transcraneal directa (tDCS) sobre a área motora primaria durante a realización dunha tarefa de tempo de reacción secuencial, potencia a aprendizaxe implícita nesa tarefa. Os mecanismos responsables desta potenciación semellan estar relacionados coa capacidade desta estimulación de inducir cambios na homeostase do cerebro. Recentes estudos mostraron que o efecto sobre a homeosticidade cortical da tDCS é altamente variable entre os individuos, feito que pon en dúbida a utilidade da tDCS como ferramenta potenciadora da aprendizaxe. Por tanto o obxectivo deste estudo será avaliar nunha mostra de 50 estudantes a resposta homeostática cortical e rendemento nunha tarefa de reacción durante a aplicación da tDCS na área motora primaria

[Abstract] Many studies proves the effects of the application of the transcranial direct current stimulation (tDCS) on the primary motor area. During the execution of a serial reaction time task (SRTT), tDCS could enhances the implicit learning of this task. The responsible mechanisms for this enhancement seem to be related to the ability of this stimulation in order to induce changes in the homeostasis of the brain. Recent studies have shown that the effects of the tDCS on the cortical homeosticity, are quite variable among individuals, which questions the utility of tDCS as a tool that promotes learning. Therefore, the objective of this study is to evaluate in a sample of 50 students, the cortical homeostatic response and performance in a reaction task during the application of tDCS in the primary motor area.
