同一个大脑区域的不同激活模式导致了相反的情绪状态
Differential activation patterns in the same brain region led to opposite emotional states
摘要：
在人类研究中，大脑区域的平均激活与人类行为的关系已经得到了广泛的研究。这种方法导致了这样的发现，积极和消极的面部偏好由不同的大脑区域代表。然而，使用多体素模式感应方法，我们发现，不同模式的扣带皮层（CC）内的神经激活在代表相反的情绪状态中发挥作用。在本研究中，虽然中性偏好的面孔，激活模式在CC对应于更高（或更低）的偏好反复诱导的模式诱导方法。结果，先前中性偏好的面孔变得更（或更少）偏好。我们的结论是，不同的激活模式的CC，而不是平均激活在不同的区域，代表和因果关系决定积极或消极的面部偏好。这种新方法可能揭示了大脑区域内激活模式在许多认知功能中的重要性。
英文摘要：
In human studies, how averaged activation in a brain region relates to human behavior has been extensively investigated. This approach has led to the finding that positive and negative facial preferences are represented by different brain regions. However, using a multi-voxel pattern induction method we found that different patterns of neural activations within the cingulate cortex (CC) play roles in representing opposite emotional states. In the present study, while neutrally-preferred faces were presented, activation patterns in the CC that corresponded to higher (or lower) preference were repeatedly induced by the pattern induction method. As a result, previously neutrally-preferred faces became more (or less) preferred. We conclude that a different activation pattern in the CC, rather than averaged activation in a different area, represents and causally determines positive or negative facial preference. This new approach may reveal importance in an activation pattern within a brain region in many cognitive functions.
