图像记忆是对短暂闪光刺激的短暂视觉记忆，是大多数视觉感知模型的重要组成部分。在这里，我们调查什么生理机制的基础上，这种能力，显示快速串行视觉呈现（RSVP）序列与和没有刺激间的差距，以人类观察员和猕猴。对于连续图像之间长达93毫秒的间隙，人类观察者和猕猴颞叶皮层中的神经元被发现继续处理刺激，就好像它仍然存在于屏幕上一样。因此，颞叶皮层神经元的持续放电可能是图像记忆的基础。基于这些发现，神经生理学视觉的图像记忆。
Iconic memory, the short-lasting visual memory of a briefly flashed stimulus, is an important component of most models of visual perception. Here we investigate what physiological mechanisms underlie this capacity by showing rapid serial visual presentation (RSVP) sequences with and without interstimulus gaps to human observers and macaque monkeys. For gaps of up to 93 ms between consecutive images, human observers and neurones in the temporal cortex of macaque monkeys were found to continue processing a stimulus as if it was still present on the screen. The continued firing of neurotics in temporal cortex may therefore underlie iconic memory. Based on these findings, a neurophysiological vision of iconic memory is presented.
