In the paper are considered the questions on the interaction of realized and unrealized information as well as the means of its processing during cognitive activity of a man. The results of investigations carried out and analysis of the data from the literature testify that the use of unrealized information is an important condition for non-standard task solving. It is provided by a cooperative activity of both hemispheres being manifested electrophysiologically as an activation of the "cognitive axis" (i.e. the foci of increased potentials' synchronization in the rostral areas of the left hemisphere and the caudal areas of the right one, revealed by means of topographic mapping of electrical processes recorded from 48 cortical points). Some cognitive styles were shown to play an important role in the organization of cooperative activity of the hemispheres at the individual level. Combination of a high synthetizing ability with a flexibility of the cognitive control provides a possibility of successful change from the work under the standard conditions to that in the non-standard situations. At the high indices of searching, intuitional activity as well as extrasensory stimuli perception the "cognitive axis" with the dominance of the focus in the right hemisphere is more expressed than that at the low indices of efficiency of the activity.
本文探讨了已实现信息与未实现信息的相互作用问题，以及人类认知活动中信息处理的方式。所开展的研究结果以及对文献数据的分析表明，使用未实现信息是解决非标准任务的重要条件。这是由两个半球的协同活动所提供的，在电生理学上表现为“认知轴”的激活（即通过对48个皮质点记录的电过程进行地形图绘制所揭示的，左半球额叶区域和右半球尾叶区域电位同步增加的焦点）。研究表明，一些认知风格在个体层面的半球协同活动组织中发挥着重要作用。高综合能力与认知控制灵活性的结合，使得从标准条件下的工作成功转变为非标准情况下的工作成为可能。在高搜索指标、直觉活动以及超感官刺激感知方面，以右半球焦点为主导的“认知轴”比在低活动效率指标时表现得更为明显。
