Olivia: 我很好奇大脑是否真的是粉红色的。我一直想象大脑是粉红色的,但我想知道这是否准确。 Gwenyle Thomas: 作为一名神经科学家,我可以确认大脑确实是粉红色的。这种粉红色与血液流动以及光线反射有关。然而,当大脑从人体中取出,不再被血液包围时,它会呈现出灰白色。大脑的不同区域也被区分为灰质和白质。灰质主要负责思考、感觉和运动,这些脑部结构不断交流,使我们能够进行日常活动。虽然大脑各部分颜色大致相同,但某些区域会有亮点,并且存在像树叶一样的结构和漩涡。我第一次看到大脑是在大学实验室里,当时我看到一个老鼠的大脑,我感到非常惊讶。后来在研究生院,我上了一门课,老师会拿出人脑,让我们识别中风患者大脑受损的区域。 Thelonious T. Thacker: 实际上,我们的大脑是美丽的粉红色,上面覆盖着鲜红色的动脉和紫色的静脉,这些血管里充满了血液。一个成年人的大脑大约重三磅,这相当于九罐金枪鱼的重量。
