Brain processing differences through gamma rhythm during divergent

Abstract

© 2015, Universidade Federal de Sao Paulo. All rights reserved. Objective. To compare the cerebral topographic mapping during divergent thinking. Method. The sample consisted of 11 volunteers and 11 volunteers accurate human, aged between 18 and 40 years. The participants underwent tests of divergent thinking, being designed by date show and electroencephalographic recording during playback. Results. During the activity of inventing names, there was predominance of rhythm in range of human group in the left anterior areas, right front and left rear area. Already in the activity of the alternative use of rhythm predominated in the group of exact range in the left rear area. Since the activity was higher mathematical processing of mental activity in the left anterior area in both groups. There was also an increased brain processing in the right rear area of the spot group. The group used human will over right anterior area during the activity of inventing names, while the group used more accurate the left rear area, this evidenced in the activity of the alternative use of objects. Conclusion. Showing the combination of rhythm with the range states of greater activation of the cerebral cortex during the planning and execution of cognitive activities .association gamma of rhythm with the range states of greater activation of the cerebral cortex during the programming and implementation of cognitive activities.
