Influence of aging and enriched environment on motor activity and emotional responses in mice.

abstract：:Clinically potent skeletal muscle relaxants are used primarily for their effects on the central nervous system. But they also have direct effects on muscle contraction that possibly involve Ca2+ channels. We compared the effects of dantrolene, an agent known to have a direct action on vertebrate skeletal muscle, with ...
