Effect of microinjections on muscle activity. Microinjection of corticotropin-releasing factor (CRF; A), kainic acid (KA; B), quisqualic acid (QA;C) and 2-amino-5-phosphonovaleric acid (APV; D) into the nucleus magnocellularis NMC of the medulla suppressed motor hyperactivity. All injection were made into the same site. CRF and KA were injected on day 2, QA was injected on day 3, and APV was injected on day 4 post-decerebration. LTB, left triceps brachii; RTB, right triceps brachii.
