Abstract
We summarize here the findings of several studies in which we analyzed the eventrelated
brain potentials (ERPs) elicited in participants with mild cognitive impairment
(MCI) and in healthy controls during performance of executive tasks. The objective
of these studies was to investigate the neural functioning associated with executive
processes in MCI. With this aim, we recorded the brain electrical activity generated
in response to stimuli in three executive control tasks (Stroop, Simon, and Go/NoGo)
adapted for use with the ERP technique. We found that the latencies of the ERP
components associated with the evaluation and categorization of the stimuli were longer
in participants with amnestic MCI than in the paired controls, particularly those with
multiple-domain amnestic MCI, and that the allocation of neural resources for attending
to the stimuli was weaker in participants with amnestic MCI. The MCI participants
also showed deficient functioning of the response selection and preparation processes
demanded by each task.
