Motor imagery is influenced by individual and contextual factors. We investigated whether the psychophysiological trait of hypnotisability modulates its subjective experience and cortical correlates similarly to what was previously shown for head postures mental images. EEG was acquired in 18 high (highs) and 15 low (lows) hypnotizable subjects (Stanford Hypnotic Susceptibility Scale, A). The experimental conditions were: baseline, a complex arm/hand movement, visual (1st person) and kinesthetic imagery of the movement. After each imagery condition, participants scored the vividness and easeness of their performance and their ability to mantain the requested modality of imagery. Subjective reports, chronometric visual/kinesthetic indices, absolute beta and fronto-central midline alpha powers were analyzed. Findings confirmed earlier reports of better kinestetic imagery ability in highs than in lows and better visual than kinesthetic imagery in lows, as well as smaller restructuring of the cortical activity in highs than in lows, during all tasks. Also, they show that hypnotisability accounts for most of the correlations between brain regions for both alpha and beta changes. Thus, imagined and actual movements were less demanding processes in highs at subjective and cortical levels. Finally, hypnotic assessment assists to plan personalized mental training for neuro-rehabilitation and sports and predict their efficacy.

催眠评估能预测运动影像和动作之间的功能对等吗？

运动图像受个人和上下文因素影响。我们调查了催眠的心理生理特征是否调节其主观体验和皮层相关性，类似于先前显示的头部姿势心理图像。脑电图是在18个高（高）和15个低（低）可催眠受试者中获得的（斯坦福催眠药敏量表，A）。实验条件为：基线，复杂的手臂/手部动作，视觉（第一人称）和动作的运动感觉图像。在每种图像条件之后，参与者对他们的表演的生动性和便捷性以及他们维护所需图像模态的能力进行评分。主观报告，测时视觉/运动指数，绝对beta和额中央正中线alpha权力进行了分析。研究结果证实了较早的报道，即在所有任务中，高低处的动觉成像能力更好，低处的视觉比运动感觉成像更好，高处的皮层活动重构比低处小。此外，他们还显示催眠性是阿尔法和贝塔变化在大脑区域之间的大部分相关性。因此，在主观和皮层水平上，想象的和实际的运动对高要求的过程都不那么严格。最后，催眠评估有助于计划针对神经康复和运动的个性化心理训练，并预测其功效。他们表明，催眠性是阿尔法和贝塔变化的大脑区域之间的大多数相关性。因此，在主观和皮层水平上，想象的和实际的运动对高要求的过程都不那么严格。最后，催眠评估有助于计划针对神经康复和运动的个性化心理训练，并预测其功效。他们表明，催眠性是阿尔法和贝塔变化的大脑区域之间的大多数相关性。因此，在主观和皮层水平上，想象的和实际的运动对高要求的过程都不那么严格。最后，催眠评估有助于规划针对神经康复和运动的个性化心理训练，并预测其功效。
