The dynamics of the EEG alpha-rhythm asymmetry was studied in 42 subjects before and in the process of verbal activity. Three groups of subjects were identified. 1. The first group was characterized by the dominant activation of the left hemisphere in the background activity and during the first presentations of functional loads. With subsequent presentations the right hemisphere became more activated. 2. In subjects of the second group the right hemisphere was initially more activated. The left hemisphere was more activated only during the first presentations of functional loads. At the final stages, their right hemisphere became again more activated. 3. The third group of subjects was identified by the high level of activation of the right hemisphere in the background activity and during the first presentations of functional loads, and by activation of the right hemisphere at the final stages.
在42名受试者进行言语活动之前及过程中，对其脑电图α波节律不对称性的动态变化进行了研究。确定了三组受试者。1. 第一组的特征是在背景活动以及首次施加功能负荷时左半球占主导激活。在随后的测试中，右半球变得更加活跃。2. 第二组受试者最初右半球更活跃。仅在首次施加功能负荷时左半球更活跃。在最后阶段，他们的右半球再次变得更活跃。3. 第三组受试者的特征是在背景活动以及首次施加功能负荷时右半球的激活水平较高，并且在最后阶段右半球也被激活。
