[The properties of the glucocorticoid receptors in the striatum and hypothalamus of rats selected for the threshold of excitability of their nervous systems].

In rats selected by their threshold sensitivity to electrical current, linear differences were found both at the receptor level and in stress-reactivity, the receptor lability being very high in the rats highly sensitive to electricity. The lower sensitivity rats were found to be more conservative in these parameters. The role of the hypothalamus and striatum in regulation of the hypophyseal-adrenocortical system through a feed-back mechanism, is discussed.
