Analysis of scalp EEG recorded in a low-noise environment

This study investigates the effects of a low-noise environment when used for recording the scalp electroencephalogram (EEG). Analysis of the EEG recordings from three volunteers confirms that clean EEG signals can be acquired in the LSBB shielded capsule without the need for notch filtering. Also, using different setups for acquiring EEG, statistical analysis reveals that the laptop computer and the patient module do not introduce any noise on the recorded signals. Moreover, the current study shows that the counting task as a mental activity can be better detected using the EEG acquired in the capsule since the relative energy of the beta band is significantly higher in this environment. Those results demonstrate the potential of the LSBB capsule for novel EEG studies.
