The time course of temporal discrimination: An ERP study.

Objective: The question of how temporal information is processed by the brain is still a matter of debate. This study aimed to elucidate the brain electrical activity associated with a visual temporal discrimination task.

Methods: For this purpose, 44 participants were required to compare pairs of sequentially presented time intervals: a fixed standard interval (1000ms), and an equal-to-standard, longer (1200ms) or shorter (800ms) comparison interval.
