Distribution of activity in the dominant (left) hemisphere was studied with a multidetector instrument during diagnostic measurements of regional cerebral blood flow in 6 patients, 4 of them neurologically normal. Computercalculated charts, in color, of the flow/activity distribution--"cerebral ideograms"-- were obtained in three situations: at rest, during motor ideation (attempts to conceive of rhythmic clenching movements of the right hand), and during actual movements of the right hand. Motor ideation changed the normal "hyperfrontal" resting flow distribution, and an increase of the hemisphere mean flow was recorded. The increase was especially marked in frontal and temporal structures. This pattern differed from the one during actual hand movements, when a rolandic flow increase was seen. The result suggests that centers for motor ideation have a different cerebral location than those which control the actual hand movement.
在6例患者（其中4例神经功能正常）进行局部脑血流诊断测量期间，使用多探测器仪器研究了优势（左）半球的活动分布。在三种情况下获得了计算机计算的血流/活动分布彩色图表——“脑表意图”：休息时、运动想象（尝试想象右手有节奏的紧握动作）时以及右手实际运动时。运动想象改变了正常的“额部血流过多”的静息血流分布，并记录到半球平均血流增加。这种增加在额叶和颞叶结构中尤为明显。这种模式与实际手部运动时不同，实际手部运动时可见中央沟血流增加。结果表明，运动想象中枢与控制实际手部运动的中枢在大脑中的位置不同。
