Single neurons in several brain areas intervening between sensation and action signal the accumulation of sensory evidence favoring a particular behavioral response. Two new studies show that these same neurons encode decision confidence and that decision makers continue to process relevant sensory information even after a choice has been made.
在感觉与行动之间起中介作用的几个脑区中的单个神经元,会发出有利于特定行为反应的感觉证据积累的信号。两项新研究表明,这些相同的神经元编码决策信心,而且决策者即使在做出选择之后仍会继续处理相关的感觉信息。
