摘要

研究了脑力劳动时脑血流量和神经活动的变化。多通道流变脑电图(REG)和地形脑电图(EEG)被用来测量受试者对三个水平的数学处理(MP)的反应，并由改进版的WPAFB标准任务集计算机程序管理。分析REG记录，提供MP期间左右半球血流动力学变化指标。脑电图数据经过数学转换，提供了反映执行每个测试序列所需的代谢负荷的头皮电势的能量密度分布。同时使用这些REG和EEG程序也可用于各种疾病状态的研究，如脑损伤和神经康复。

Rheoencephalographic and electroencephalographic analysis of cognitive workload

Changes in brain blood flow and neural activity during mental work are investigated. Multichannel rheoencephalography (REG) and topographical electroencephalography (EEG) were used to measure subject responses to three levels of mathematical processing (MP), as administered by a modified version of the WPAFB criterion task set computer program. REG records were analyzed to provide indices of right and left hemisphere hemodynamic changes during MP. The EEG data were mathematically transformed to provide energy density distribution of the scalp electropotential which reflect the metabolic load required to perform each test sequence. The simultaneous use of these REG and EEG procedures may also be used in the study of a variety of disease states, such as brain injury and neurorehabilitation.<>
