Identification Of Changes In EEG Signals Due To Motor Imagination

In this study, the Electroencephalogram (EEG) was examined to address the effect of motor imagination on the motor cortex region, as it is known that the neuronal activity produced during motor imagination is same as the neuronal activity produced during real executed movement. ERD and ERS give an idea about the activated and ideal condition of the cortical areas respectively. The EEG signals for subjects were acquired during left and right hand motor imagination from motor cortex region. Bandpower and Entropy were extracted as features from the EEG signals. The EEG signals were divided into sub frequency band of interest which is alpha band. Naive Bayes classifier has been used for classification of motor imagination in the present study.
