| Summary: | Control system that used mind as controller is being developed using Brain-Computer Interface (BCI), which allowed communication between human brain and machine. BCI can be used to read mental activity such as motor imagery. The problem in BCI usage is relatively low viability. One reason of that is because brain signal is not strong enough to be processed by machine. Mirror neuron, which evoked by action observation, has similar but stronger activity and may have connection with motor imagery. 6 healthy male are involved in this experiment and split into 2 groups: control and experimental. The experimental group was asked to perform motor imagery exercise with action observation, and control group was asked to perform motor imagery exercise without action observation. Then, electroencephalograph (EEG) was recorded from both groups while doing 3 motor imagery task: rest, walk, and jump. Power Spectral Density (PSD) was calculated from EEG to measure wave desynchronization value which is PSD decrease from rest to walk or jump. Results shows that experimental group had greater Mu wave (7-13 Hz) and Beta wave (16-24 Hz) desynchronization value. We conclude that mirror neuron has connection with motor imagery and may be used to enhance motor imagery strength in BCI usage exercise. |
