The role of posterior parietal cortices on prismatic adaptation effects on the representation of time intervals

We found an abolition of the effects of PA on time when rTMS was delivered on the left and not on the right PPC, regardless of the task and moreover, when the participants responded and adapted with the right hand and also with the left hand. This result suggests a direct involvement of the left PPC in the interactive process, between spatial modulations induced by PA and the spatial representation of time, that does not depend on motor processes. This study provides useful results for future investigations on the neural mechanisms subtending the effects of PA on spatial representations.
