Hormonal imbalances during development may have long-lasting effects. Using functional magnetic resonance imaging (fMRI), we compared 14 youths with Congenital Adrenal Hyperplasia (CAH), a genetic disorder of hormonal dysfunction, with 22 healthy controls on memory encoding of emotional faces. Patients remembered fewer faces than controls, particularly fearful faces. FMRI data to successfully encoded fearful faces revealed that males with CAH showed significant activations in amygdala, hippocampus, and anterior cingulate relative to unaffected males, while females with CAH demonstrated deactivations relative to unaffected females in these regions. Findings indicate that steroid abnormalities during development can have important effects on neural correlates of emotional memory.
发育过程中的激素失衡可能会产生长期影响。我们使用功能磁共振成像(fMRI),将14名患有先天性肾上腺皮质增生症(CAH,一种激素功能障碍的遗传性疾病)的青少年与22名健康对照者进行了比较,研究他们对情绪面孔的记忆编码。患者记住的面孔比对照组少,尤其是恐惧面孔。对成功编码的恐惧面孔的fMRI数据显示,患有CAH的男性相对于未受影响的男性,杏仁核、海马体和前扣带回有显著激活,而患有CAH的女性相对于未受影响的女性,这些区域则表现为失活。研究结果表明,发育过程中的类固醇异常会对情绪记忆的神经关联产生重要影响。
