【Abstract】 The computer EEG topographical（CET） features of 40 cases of multiple brain infarction （group A） and 20 cases of single brain infarction （group B） were studied and compared with those of 40 normal persons（group C）. Both the group A and B were identified with CT scanning of the herd. The results showed that （1） the δ and θ band powers in group A, B and C were 15.04±4.86 and 17.16±4.31,14.55±7.66 and 18.55±5.76,and 10.63±1.53 and 10.80± 2.33μv（mean±SD）, respectively; （2）the α₁ and α₂ band powers in group A,B and C were 16.36±7.50 and 12.36±5.46,14.30±5.25, and 13.55±5.09, and 21.76±12.06. and 17.46±8.9 4,respectively, （3） the proportions of asymmetrical distributions of δ,θ and σ₁ bands in group A and B were increased significantly; （4）focal δ and θ band power increased areas were defected only in group B, while more than one focal δ and θ band power increased areas occured in a part cases of group A, besides, diffused δ and θ band power increased areas were found in some cases of group A.更多还原
