脑电图研究结果揭示了恐惧如何在大脑中传递

"We have known for a long time that the brain prioritizes threatening information over other cognitive processes," explained Bambi DeLaRosa, study lead author. "These findings show us how this happens. Theta wave activity starts in the back of the brain, in it's fear center -- the amygdala -- and then interacts with brain's memory center -- the hippocampus -- before traveling to the frontal lobe where thought processing areas are engaged. At the same time, beta wave activity indicates that the motor cortex is revving up in case the feet need to move to avoid the perceived threat."

“我们很早就知道大脑对威胁信息的敏感度要高于其他认知过程，”该研究的首席作者Bambi DeLaRosa解释道。“这些发现向我们展示了它是如果发生的。θ波活动开始于位于大脑后部的恐惧中心——杏仁核——然后在前往思维加工区域，大脑额叶之前，与大脑记忆中心——海马体——相互作用。同时，β波活动表明，在需要移动位置以避免威胁时，运动皮层加速加速运转。”

For the study, 26 adults (19 female, 7 male), ages 19-30 were shown 224 randomized images that were either unidentifiably scrambled or real pictures. Real pictures were separated into two categories: threatening (weapons, combat, nature or animals) and non-threatening (pleasant situations, food, nature or animals).
