چکیده انگلیسی
Although movement is controlled by different descending pathways, it remains unknown whether the integration of visual feedback and motor learning differs for movements controlled by different descending pathways. Here, we compare motor control and learning of the ankle joint and tongue because they are primarily controlled by the corticospinal and corticobulbar pathways, respectively. Twelve young adults (19.63â¯Â±â¯2.11â¯years, 6 females) practiced a tracking task (combination of 0.02, 0.37, 0.5, and 1â¯Hz) with ankle dorsiflexion and with tongue elevation for 100 trials. The participants practiced each effector (ankle and tongue) in different days and the order of the effector was counterbalanced. Following practice, participants performed the same tracking task with concurrent contractions of the tongue and ankle (dual tracking task; transfer) with three different visual feedback conditions (no visual feedback, visual feedback only for ankle, visual feedback only for tongue). We quantified the force accuracy (RMSE) from each effector during the practice and transfer periods. During practice, the force accuracy and performance improvement to the visuomotor task was greater for the ankle dorsiflexion than tongue elevation. During the transfer task, the ankle dorsiflexion was more accurate than tongue elevation, independent of whether visual feedback was given for the ankle or tongue. The greater performance improvement for the ankle dorsiflexion during practice was related to superior transfer performance. These findings suggest that the corticospinal pathway integrates visual feedback more efficiently than the corticobulbar pathway, which enhances performance and learning of visuomotor tasks.
