| Outline of Final Research Achievements |
This project investigated the mechanisms by which the perception of sensory information is modified by action. When performing a goal-directed action, humans learn the action by making use of the difference between the goal and the actually performed action (error). Here, we focused on the perception of 'error'. Previous theories of motor learning have assumed that the brain can accurately estimate these errors, and that if errors cannot be successfully corrected, it is because the motor system cannot make good use of the errors. However, the present study found that in fact, depending on the pattern in which the error occurs, the 'estimation' of the error can be inaccurate, which can impede motor learning, and such estimation error is reflected as an activity in the posterior parietal cortex.

これまで、感覚・知覚情報処理と運動を作り出すための情報処理は全く異なる処理であると考えられ、別々に研究がなされてきました。しかし、私のこれまでの研究も含め、知覚は単に感覚入力の特徴に依存するわけではなく、その入力に対しどのように関わるかを反映することが明らかになりつつあります。本研究では、自らの運動によって作り出される「誤差」の感覚情報が、運動の影響を受けて変容し、されにはそれによって、運動学習を阻害するという円環関係を、脳のメカニズムも含めて明らかにしました。
