fMRI research on memorized finger tapping: the neural correlates of memorizing, planning, and controlling

In a delayed-response task, subjects watched and memorized number strings like 4-1-4-2-3, then tapped the corresponding finger (1 - index; 2 - mmiddle;3 - ring; 4 - little finger) with the thumb in the order indicated by the sequence, when the triggering signal appeared. Results showed activations of dorsal and ventral prefrontal cortex, precentral gyrus, and Sylvian fissure. The prefrontal cortex was expected to be related to memorizing and planning, while the motor cortex to tapping. Sylvian fissure was suggested to be involved in feedback process in this task.IUPsy
