Performance of healthy persons under pain in different cognitive load tasks: An event-related potential study on experimental pain individuals.

ABSTRACT:

Objective

This study aims to determine how brain activities underlying task with different cognitive load would be modulated by the painful state using electroencephalography.

Methods

The pain state was established by spraying capsaicin on subjects' left inner forearm. A total of 20 experimental pain subjects and 20 matched nonpain controls underwent cognitive tasks with electroencephalogram recording. We collected and analyzed behavioral and event-related potential (ERP) data.

Results

High cognitive tasks exhibited significantly longer response times and lower accuracies than low-load tasks. The experimental pain group displayed a significantly lower accuracy than the control group. In addition, the experimental pain group showed no significance between high and low
