Research Abstract |
In order to learn novel actions, it is essential to observe and imitatesimilar actions performed by other individuals. We used 24-channel near-infrared spectroscopy to investigate brain activity during the observation of sequentially presented meaningless postures. The results revealed that the oxy-haemoglobin concentrations in the lower part of the precentral gyrus increased to a greater extent during the observation. This suggests that the area related to action plans, that is the human mirror-neuron system, is activated when observers recognize the possibility of body movement even during the observation of static meaningless postures.
