The amygdala is a brain region that coordinates fear responses to a variety of threats. Ziemann et al. (2009) now show that acid-sensing channels in the amygdala mediate fear responses that accompany inhalation of carbon dioxide, suggesting that aberrant chemosensation may underlie anxiety disorders associated with a fear of suffocation.
杏仁核是一个协调对各种威胁产生恐惧反应的脑区。齐曼等人（2009年）现在表明，杏仁核中的酸敏感通道介导了伴随吸入二氧化碳而产生的恐惧反应，这表明异常的化学感觉可能是与窒息恐惧相关的焦虑症的潜在原因。
