This paper proposes a new method of the distiniction method of the newborn rat brain damage using heart beat interval information. We investigated the factor related to the brain damage by using the hypoxic-ischemic encephalopathy model of the newborn rat. From the experiment results, significant factors were the coefficient of variation of the heartbeat intervals and the histogram information. The proposed distinction method succeeded in 21 distinctions in 25 newborn rats (brain non-damage 16 and brain damage 9). This paper shows that it becomes possible to judge the brain damage of an actual embryo by using the heartbeat interval information at the early stage.
