Fixation Task Training in Macaque Monkey and Factors Affecting Fixation

Abstract

In vision research, the monkey training for fixation is indispensible for the data acquisition. The authors introduce the improved method to shorten the training period for the monkeys and examine the factors affecting the performance of the trained monkey. We introduce two new concepts. One is the minimal reaction time which can evaluate more accurate success rate(%), and the other is the % variation of bright light period which can control the difficulty of training and ensure the fixation of monkey substantially. It took an average of 72 days to train the monkeys. The factors affecting the performance of the trained monkey are the bright light period, the dim light period, the variation of the bright light period, and water deprivation. Our training procedures with minor modification were effective and easy to reach end point of training. If further training for the detailed experiment is needed in these monkeys, these can be achieved by properly controlling these factors.
