P 70. The role of parietal cortex in awareness of motor intention – human rTMS study

Conclusion: The neural processing in the left PC might be important for the awareness of the intention to move, because the duration from the intention to movement was prolonged after the transient suppression of the left PC. One previous study showed the decrease that duration in patients with PC lesion (Sirigu, 2004). However, there are another study reporting the normal W-judgment time in those patients (Lafargue, 2008). This controversy may be due to the functional compensation in the chronic stage. The functional suppression induced by rTMS may be similar to the acute one, so that the present results cannot be directly comparable to the chronic stroke patients. However, at least, our results suggest the essential role of the left PC in the generation of the intention to move, although the exact role of the left PC is not known yet.
