Spontaneous pupillary movements in darkness were recorded (1) in healthy subjects of different ages when they were rested or fatigued, (2) in chronically tired subjects without known neurological defects, and (3) in patients with various neurological lesions. In some of the experiments, local or systemic drugs were used. While the pupils are large and quiet in darkness when the subject is alert, they oscillate under the influence of tiredness. Waves of spontaneous pupillary contraction and dilation accompany periods of increasing sleepiness and spontaneous arousal until, at the moment immediately preceding sleep, the pupils become very small. The mechanism of these movements was analyzed and a simple test described which allows the objective determination of the degree of acute fatigue in a given subject at a given time. In the light of these results, the concepts of 'normal' and of 'pathologic' fatigue were discussed. (Author).
