Corticosterone decreases 3H-glutamate binding in rat hippocampal formation.

abstract：:In the present article we report that in vivo LHRH output as measured at the anterior pituitary following castration significantly increased, due to larger and more frequent LHRH signals arriving to this gland. This contrasts with the decreased amplitude and overall mean LHRH release of castrate males bearing a push-p...
