Time is a fundamental dimension of life. It is crucial for decisions about quantity, speed of movement and rate of return, as well as for motor control in walking, speech, playing or appreciating music, and participating in sports. Traditionally, the way in which time is perceived, represented and estimated has been explained using a pacemaker-accumulator model that is not only straightforward, but also surprisingly powerful in explaining behavioural and biological data. However, recent advances have challenged this traditional view. It is now proposed that the brain represents time in a distributed manner and tells the time by detecting the coincidental activation of different neural populations.
时间是生命的一个基本维度。它对于有关数量、运动速度和回报率的决策至关重要,对于行走、说话、演奏或欣赏音乐以及参与体育运动中的运动控制也很关键。传统上,人们使用起搏器 - 累加器模型来解释时间的感知、表征和估计方式,该模型不仅简单直接,而且在解释行为和生物学数据方面具有惊人的强大能力。然而,最近的进展对这一传统观点提出了挑战。现在有人提出,大脑以分布式方式表征时间,并通过检测不同神经群体的同时激活来判断时间。
