Recent studies have found that positive affect is associated with greater relative left frontal EEG activation and negative affect is associated with greater relative right frontal EEG activation. Further, chronically depressed adults typically display stable right frontal EEG activation. The present study investigated the effects of music on mood state and right frontal EEG activation associated with chronic depression. Fourteen chronically depressed female adolescents listened to rock music for a 23-minute session. These adolescents were compared with a control sample of chronically depressed female adolescents who were simply asked to sit and relax their minds and their muscles for the same time period. EEG was recorded during baseline, music, and postmusic for three minutes each, and saliva samples were collected before and after the session to determine the effects of the music on stress hormone (cortisol) levels. No group differences or changes were noted for observed or reported mood state. However, cortisol levels decreased and relative right frontal activation was significantly attenuated during and after the music procedure. It was concluded that music had positive effects on the physiological and biochemical measures even though observed and self-reported mood did not change.
近期研究发现，积极情绪与相对更强的左侧额叶脑电图激活有关，消极情绪与相对更强的右侧额叶脑电图激活有关。此外，长期抑郁的成年人通常表现出稳定的右侧额叶脑电图激活。本研究调查了音乐对情绪状态以及与慢性抑郁症相关的右侧额叶脑电图激活的影响。14名长期抑郁的女性青少年听了23分钟的摇滚音乐。这些青少年与一组对照样本进行了比较，该对照样本为长期抑郁的女性青少年，她们只是被要求在相同时间段内静坐并放松身心。在基线期、听音乐期间和听音乐后分别记录3分钟的脑电图，并在实验前后采集唾液样本，以确定音乐对压力激素（皮质醇）水平的影响。在观察到的或报告的情绪状态方面，未发现组间差异或变化。然而，在听音乐过程中和听音乐后，皮质醇水平下降，右侧额叶相对激活明显减弱。研究得出结论，尽管观察到的和自我报告的情绪没有变化，但音乐对生理和生化指标有积极影响。
