In order to study the effect of drugs on sleep, it would be useful to have quantitative information about rapid eye movements (REMs) in a REM sleep period (REMP). It has been difficult to obtain detailed information on REMs in REMP, because there are many problems in the conventional method. In this paper, a new analysis method developed in order to solve the problems in the conventional method is presented. The new method has made it possible to compute the eye ball movement displacement, velocity and REM-momentum which mean the amount of ocular activity.<BR>The new method was applied to 133 REM sleep records of 13 normal young adults. The result of analysis with respect to the records were as follows : 1) REMs could be classfied into two types-REMs with the high movement velocity and the low movement velocity. 2) Higher the amplitude of the REMs the exponentially lower becomes the average number of appearance. 3) The REM activity in a REMP had three kinds of periodicity components consisting of 5 minutes, 10 minutes and 20 minutes.
