Abstract
Evidence from previous studies has suggested that motor imagery and motor action engage overlapping
brain systems. As a result of this observation that motor imagery can activate brain regions associated
with actual motor movement, motor imagery is expected to enhance motor skill performance and become
an underlying principle for physical training in sports and physical rehabilitation. However, few studies
have examined the effects of physical training on motor imagery in beginners. Also, differences in neural
networks related to motor imagery before and after training have seldom been studied. In the current
study, using functional magnetic resonance imaging (fMRI), we investigated the question of whether
motor imagery can reflect plastic changes of neural correlates associated with intensive training. In fact,
motor imagery was used in this study as a tool to assess the brain areas involved in shooting and involved
in learning of shooting. We discovered that use of motor imagery resulted in recruitment of widely
distributed common cortical areas, which were suggested to play a role in generation and maintenance
of mental images before and after 90 h of shooting training. In addition to these common areas, brain
activation before and after 90 h of shooting practice showed regionally distinct patterns of activity change
in subcortical motor areas. That is, basal ganglia showed increased activity after 90 h of shooting practice,
suggesting the occurrence of plastic change in association with gains in performance and reinforcement
learning. Therefore, our results suggest that, in order to reach a level of expertise, the brain would change
through initial reinforcement of preexistent connections during the training period and then use more
focused neural correlates through formation of new connections.
