人类的个性与大脑有关，对生物过程产生多种影响。本研究探讨情绪人格与心脏活动的关系。我们的数据表明，情绪个性与静息心电图（ECG）中特定的心脏振幅特征有关。两个使用功能性磁共振成像的实验表明，在处理具有情感效价的音乐刺激时，这种特征与杏仁核和海马体的大脑活动相关。此外，该心脏特征与情绪的主观指数（如通过修订的多伦多述情障碍量表测量的）相关，并且与心率变异性的时域和频域测量相关。研究结果表明，心电图振幅模式提供了比以前认为的更多的关于个人情绪的信息，从而证明了情绪人格与心脏之间的复杂联系。情绪人格的心脏特征的发现为研究情绪失衡与心血管疾病之间的关系开辟了新的视角。
Human personality has brain correlates that exert manifold influences on biological processes. This study investigates relations between emotional personality and heart activity. Our data demonstrate that emotional personality is related to a specific cardiac amplitude signature in the resting electrocardiogram (ECG). Two experiments using functional magnetic resonance imaging show that this signature correlates with brain activity in the amygdala and the hippocampus during the processing of musical stimuli with emotional valence. Additionally, this cardiac signature correlates with subjective indices of emotionality (as measured by the Revised Toronto Alexithymia Scale), and with both time and frequency domain measures of the heart rate variability. The results demonstrate intricate connections between emotional personality and the heart by showing that ECG amplitude patterns provide considerably more information about an individual's emotionality than previously believed. The finding of a cardiac signature of emotional personality opens new perspectives for the investigation of relations between emotional dysbalance and cardiovascular disease.
