The probability distribution of the amplitude of scalp electroencephalogram has been investigated in an adult subject in the idle state, and during performance of a mental arithmetic task. Based on a large sample, the electroencephalogram in this subject in the idle state follows a Gaussian (normal) probability function 66 percent of the time. During performance of the arithmetic task, the portion of Gaussian electroencephalogram decreases to 32 percent. The probability function characterizing gross electroencephalographic activity is determined by the degree of mutual interaction of individual cellular generators of wave activity in the tissue underneath the recording electrode. The data imply an increase in the cooperative activity of cortical neuronal elements during performance of a mental task.
已对一名成年受试者在空闲状态以及进行心算任务期间头皮脑电图振幅的概率分布进行了研究。基于大量样本，该受试者在空闲状态下的脑电图有66%的时间遵循高斯（正态）概率函数。在心算任务进行期间，呈高斯分布的脑电图比例降至32%。表征总体脑电图活动的概率函数由记录电极下方组织中单个波活动细胞发生器的相互作用程度决定。这些数据表明在执行心理任务期间皮质神经元元件的协同活动增加。
