Ion Channels—Molecules in Action

the physics, chemistry and molecular biology used for Since the discovery of ion channels in excitable memion channel research. For example, tobegin a discussion branes of the nervous system, ion channels have been of electricity they did not neglect to say that “charges found in practically every eukaryotic cell type that has of the same sign repel each other and those of the been studied, as ...

Action mirroring and action understanding in children

The past decade has experienced an increasing interest in action underestanding and children’s mirroring of others’ behavior. Behavioral investigations have focused on the development and significance of mimicry, goal prediction and imitation. Others have focused on the neural basis of action mirroring, identifying particular electrophysiological markers or related brain regions. A vivid debate...

The Biological Mechanisms of Air Ion Action

Negative air ions are shown to decrease 5-hydroxytryptamine concentrations in extirpated strips of rabbit trachea and in the respiratory tracts of living mice. An initial exposure of guinea pigs to (-) air ions causes a transient rise in urinary 5-hydroxyindoleacetic acid excretion which is not observed upon subsequent exposures. These findings are compatible with the hypothesis advanced earlie...

The action of calcium ion on cardiac phosphorylase b kinase.

Nonactivated phosphorylase b kinase has been purified from beef hearts. Kinase-activating factor which is required for calcium activation of kinase and an inhibitory factor which prevents calcium activation were also partially purified. Kinase, kinase-activating factor, and inhibitory factor were each obtained essentially free of the other. The action of kinase-activating factor was proportiona...
