摘要
After 300 - 500 ms of various movements, a significant rebound in beta rhythm power is observed. This phenomenon is called Post-Movement Beta Rebound (PMBR). Previous studies have been carried out in a single movement context in the exploration of its functional significance, and few studies have been conducted in connected movements. Therefore, this study used the cue-induced delayed task paradigm to examine the PMBR change in the motor cortex of the 20 adults when they were moving under the single or connected movements condition. It was found on right-hand movements that the PMBR of the first movement in a connected condition was stronger than that of a single movement, and it was also observed on both left- and right-hand movements that the PMBR of the first movement was stronger than that of the last movement in a connected condition. The results show that the PMBR after the connected movement was stronger than the no movement connection, reflecting that PMBR plays an important role in the preparation of subsequent movements.
