The authors have studied in 31 patients affected by right (N = 12) or left (N = 19) hemispheric lesions and in 10 normal controls the autonomous response to emotional stimuli. Stimuli consisted of 3 short films, aiming to provoke respectively a negative emotional reaction, a positive emotional response or a non-emotional reaction. Galvanic skin response and heart rate were considered as the dependent variables of our research. Both normal controls and left brain-damaged patients were very influenced by the emotional nature of the stimuli and showed clear signs of activation of the sympathetic and para-sympathetic systems in front of emotional films. By contrast, right brain-damaged patients were not influenced by the emotional or non-emotional nature of the stimuli and showed neither a clear galvanic skin response nor a significant decrease of heart rate in front of emotional films.
作者对31例患有右半球（N = 12）或左半球（N = 19）病变的患者以及10名正常对照者对情绪刺激的自主反应进行了研究。刺激包括3部短片，分别旨在引发负面情绪反应、正面情绪反应或无情绪反应。皮肤电反应和心率被视为我们研究的因变量。正常对照者和左脑损伤患者都受到刺激情绪性质的很大影响，并且在观看情绪影片时表现出交感神经和副交感神经系统激活的明显迹象。相比之下，右脑损伤患者不受刺激的情绪或非情绪性质的影响，在观看情绪影片时既没有明显的皮肤电反应，心率也没有显著下降。
