One of the most strikingcharacteristics of Graves disease is the patients loss ofcontrol and his increased susceptibility to stinuih, especiahyto trauma and to fear and to the adnrinistration of thyroidextract. It has been shown that the various causes of thedischarge of ner\(jus energy produce alterations in the ner-vous system and j^roljaljly in the thyroid gland. This isespecially tiiie of the fear stimulus, and has been clearlydemonstrated in the brains of rabbits which had been sub-jected to fear alone fFig. 13). Of special interest was theeffect of daily fright. In this case the l)rain-cells showed adistinct change, although the animal had been subjected tono fear for twenty-four hours before it was killed (Fig. 13 C).
