ABSTRACT

This chapter traces the time frame of stimulation to activity in the oculomotor system by neatly organizing a broad and eclectic data base. These latency data are then used to develop a new model of saccadic emissions which when applied to new data provides a quantum leap in the understanding of oculomotor system and new insight into the possibility that "procrastination" leads to efficiency. Neurophysiological studies in various parts of the brain confirm the shortness of latencies both between visual stimuli and the first electrical responses in different visual areas, and also between electrical stimulation in the oculomotor system and actual saccadic movement. The bulk of the saccadic latency seems to be simply some kind of oculomotor procrastination. A typical saccade of 10° lasts about 50 msec, during which the high rate of visual slip, amongst other factors, renders the visual system all but blind.
