虽然许多高级皮层区域与时间有关，但在过去十年中，即使在视觉系统的最早皮层阶段也观察到了时间活动。这种活动已被正式建模为一个所产生的强化信号，导致可检验的假设与最近的实验支持，证明该强化信号的必要性和充分性。正如在其他涉及计时的皮层区域中所观察到的那样，视觉皮层内的间隔计时活动遵守时间标量属性。最后，间隔计时期间视觉皮层的扰动导致计时的合法偏移。这些和相关的观察推进了这样一个概念，即视觉皮层是学习和表达视觉相关的时间期望的基底，这些期望支配着行为相关的动作。
While many high-level cortical areas have been implicated in timing, timing activity has also been observed even in the earliest cortical stages of the visual system over the past decade. This activity has been formally modeled as one arising from a reinforcement signal, leading to testable hypotheses with recent experimental support, demonstrating the necessity and sufficiency of that reinforcement signal. As observed in other cortical areas implicated in timing, interval timing activity within the visual cortex abides by the temporal scalar property. Finally, perturbations of the visual cortex during interval timing results in lawful shifts in timing. These and related observations advance the notion that visual cortex is a substrate for learning and expressing visually-associated temporal expectations governing behaviorally-relevant actions.
