There were differences -- long-term romantic love lit up many more brain regions than early-stage love -- but both groups showed significant activity in the dopamine-rich ventral tegmental area .

也有一些不同长期的浪漫爱情会比短期爱情调动大脑的更多区域，但是两组都检测到了多巴胺富集的腹侧被盖区的重要活动。

For instance when a male zebra finch sings a courtship song to a female nerve cells in a part of his brain called the ventral tegmental area become activated .

例如，当一只雄性斑马雀（zebrafinch）对雌性鸣唱一支求偶曲时，在它大脑的神经细胞部分称为腹侧被盖区的部分开始活跃。
