Kinematics results. Panel a and c: Mean speed normalized by the mean of each subject and averaged over FG and EG subjects respectively. Panel b and d: Time to peak ratio averaged over FG and EG subjects respectively. %Task identifies the relative ordinal number of the task-movements of all the sequence. In all panels shaded areas indicate the standard error, the blue portions refer to the first 20% of the task while the red corresponds to the remaining 80%
