Event related desynchronization. Significant activation in group analysis is shown (p < 0.05). Changes in the beta-frequency-band during pneumatic pharyngeal activation compared to the resting stage. a) ERD evoked by pneumatic stimulation to the left side of the pharyngeal wall. Stronger and broader activation is found in the temporal lobe of the left hemisphere. b) ERD evoked by pneumatic stimulation of the right side of the pharyngeal wall. Here a right hemispheric lateralization of temporal activation can be seen. The color bar represents the t-value.
