Average motor behavioral data displayed in figures. Means (SEM) for catalepsy, spontaneous activity forelimb and hindlimb (total number of steps), and challenging beam traversal (sec), time to traverse last third (seconds), foot faults (average over 5 trials) for vocalexercise-trained and sham-trained animals at 4, 6 and 8 mo of age.
