时序知觉指对两个事件是否同时出现以及相继出现时彼此先后顺序的知觉,是我们理解语音、欣赏音乐、参与体育运动等行为的基础.本文总结了近10年来几百毫秒内的时序知觉的行为脑损伤、脑成像与电生理研究成果,发现时序知觉受到刺激通道、属性、特征以及任务类型的影响;单通道的时序知觉主要激活颞顶联合部、顶内沟、前运动与辅助运动区、前额叶等脑区,而跨通道的时序知觉主要激活顶下叶、顶内沟、脑岛和上丘等脑区.综合来看,时序知觉既有中枢计时也有分布计时,两种计时机制的本质差异与时序信息的神经表征有关.后续研究需要结合各种研究手段,探索计时机制与时序加工过程的关系,揭示时序加工所激活的各个脑区的功能,以解决这一领域内存在的众多争议.
Tense perception refers to the perception of whether the two events occur simultaneously and one after the other in succession, which is the basis of our understanding of speech, music appreciation, participation in sports, etc. This paper summarizes the perception of timing in hundreds of milliseconds in the recent 10 years Behavioral brain injury, brain imaging and electrophysiological findings, we found that timing perception is affected by the stimulation channel, properties, characteristics and task types; single-channel temporal perception mainly activates the temporo-cephalic junction, the apex intima, the anterior and ancillary motor areas , Prefrontal cortex and other brain regions, while the cross-channel temporal awareness mainly activates the top of the lower lobe, the top of the inner groove, the insula and the superior colliculus and other brain regions.Overall, timing perception both central timing and distribution timing, two timing mechanisms The nature of the difference is related to the neural representation of timing information.Researched research needs to combine various research methods to explore the relationship between the timing mechanism and the timing process and to reveal the functions of the various brain regions activated by the timing process to solve the problems existing in this field Many controversies.
