The present study investigated electrocortical and cardiovascular reactivity during positive and negative emotion, and examined the relation of asymmetric frontal lobe activation to cardiovascular responses. Participants were 30 healthy, right-handed university students (mean age, 23.9; 60% female; 76% Caucasian). Electroencephalographic (EEG), blood pressure (BP), and heart rate (HR) responses were assessed while subjects engaged in laboratory tasks (personally-relevant recall tasks and film clips) designed to elicit happiness or anger. Happiness-inducing tasks evoked more prominent left than right frontal EEG activation, and greater left frontal EEG activation than anger-inducing tasks. However, anger-inducing tasks were, on average, associated with comparable left and right frontal EEG activation. Irrespective of emotional valence, cardiovascular activation was more pronounced during personally-relevant recall tasks than during the viewing of film clips. During anger recall, both greater left frontal EEG response (r=-0.46, P<0.02) and greater right frontal EEG response (r=-0.45, P<0.02) were correlated significantly with increased HR reactivity during the task. In addition, a right lateralized frontal EEG response during anger-inducing tasks was associated with greater concomitant systolic BP (P<0.03) and diastolic BP (P<0.008) reactivity. Exploratory analyses also indicated that men who displayed a left lateralized frontal EEG response during happiness-inducing tasks showed the greatest concomitant systolic BP and HR reactivity (P's<0.03). These findings suggest that asymmetric frontal EEG responses to emotional arousal may elicit different patterns of cardiovascular reactivity in healthy adults.
本研究调查了正负情绪期间的脑电活动和心血管反应，并检验了额叶不对称激活与心血管反应之间的关系。研究对象为30名健康的右利手大学生（平均年龄23.9岁；60%为女性；76%为白种人）。在受试者进行旨在诱发快乐或愤怒的实验室任务（个人相关回忆任务和电影片段）时，评估其脑电图（EEG）、血压（BP）和心率（HR）反应。诱发快乐的任务比诱发愤怒的任务在左侧额叶诱发更显著的EEG激活，且诱发快乐的任务比诱发愤怒的任务在左侧额叶诱发的EEG激活更大。然而，平均而言，诱发愤怒的任务在左右额叶诱发的EEG激活相当。无论情绪效价如何，与观看电影片段相比，个人相关回忆任务期间的心血管激活更为明显。在愤怒回忆期间，左侧额叶EEG反应增强（r = -0.46，P < 0.02）和右侧额叶EEG反应增强（r = -0.45，P < 0.02）均与任务期间HR反应性增加显著相关。此外，诱发愤怒任务期间右侧额叶EEG反应与收缩压（P < 0.03）和舒张压（P < 0.008）反应性增强相关。探索性分析还表明，在诱发快乐任务期间表现出左侧额叶EEG反应的男性，其收缩压和HR反应性增强最为显著（P < 0.03）。这些发现表明，健康成年人对情绪唤醒的额叶不对称EEG反应可能引发不同模式的心血管反应。
