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 mechanism of action of anticholinesterase compounds on the patellar reflex.

In a previous report (McNamara et at., 1954) it was noted that spinal reflexes could be abolished reversibly by anticholinesterase compounds. When the ammals were sacrificed after return of the reflex activity, some were found to have considerable cholinesterase in their spinal cords and in other areas of the body; in other animals the enzyme was apparently absent. No determinations of acetylch...

Mental simulation of an action modulates the excitability of spinal reflex pathways in man.

The question of whether mental simulation of an action has an effect on the spinal reflex circuits was examined in normal humans. Subjects were instructed either to exert or to mentally simulate a strong or a weak pressure on a pedal with the left or the right foot. Changes in the H- and T-reflexes activated by electrical and mechanical stimuli were measured on both legs during motor performanc...
