Invasive experiments could be employed on the monkey as subject instead of the human, to understand how brain is working on these processes. In this paper, we have described a system applying to visually guided reaching tasks on the monkey by using two dimensional SPIDAR to identify active areas of brain involved in the calculation of kinematics and dynamics in positron emission tomography (PET) experiments. The two dimensional SPIDAR is applicable to two different types of reaching movement tasks, in which counter force is produced to the hand or visual rotation is produced to the cursor.
