Objective : This study finds out the difference in brain activation according to the preferable imagery when recognizing sense of touch.
Methods: The research target was based on 15 people composed of 10 males (66.7%) and 5 females (33.3%). The average age was 22.2l±2.39. For the Electroencephalogram (BEG), was measured to eight parts including left prefrontal, right prefrontal, left temporal, right temporal, left parietal, right parietal, left occipital, and right occipital. The measurement of EEG was done in three stages of manually detecting sense of touch while thinking about the preferred image. The acquired EEG was analyzed qualitatively through power spectrum analysis to calculate the target power value. Paired t-test was executed for the statistical analysis according to two conditions.
Results: When passive searching for sense of touch while imaging the preferred sense, and when searching for sense of touch passively, there was significant difference in the alpha wave to the both sides of the occipital lobe. When passive searching for the preferred image, it increased even more (p<.05). In feeling sensory motor rhythm, the area did not show significant difference (p>.05).
Conclusion : This research identified that imaging the preferred senses related to feeling and emotion gives positive influence to brain activation. (J Korean Society of Neurocognitive Rehabilitation 2015;7:1-7)
