Abstract

The present study demonstrates that perithreshold temporal integration occurs in the human taste system across stimulus durations ranging from 200 to 1500 ms in a manner analogous to that seen in other major sensory systems. Thus, the notion that gustation is comparatively insensitive to temporal stimulus parameters at threshold levels is disproved.

摘要

本研究表明，在人类味觉系统中，阈上时间整合现象会在200至1500毫秒的刺激持续时间内出现，其方式类似于在其他主要感觉系统中所观察到的。因此，味觉在阈值水平对时间刺激参数相对不敏感这一观点被推翻。
