Power-spectrum analysis was performed on the a activity of 8 right-handed subjects recorded under 3 conditions : (1) rest with eyes open (REST), (2) word retrieval task (Verbal Fluency test : VF), and (3) constructional tasks (Block Design test with the right hand : RB, with the left hand : LB). These tests were employed to assess frontal lobe functionings and planning abilities. α-power values in VF significantly reduced on Fpl and C3 as compared with REST. However, no significant difference was found between REST and RB, nor between REST and LB. These results suggest that the left forebrain contributes to planning for word retrieval, and that the performance of Block Design test may require interhemispheric cooperation.
