视觉大脑会快速地对刺激进行分类，以产生情绪影响，尽管在一个持续的、连续的700张复杂图片的洪流中高速呈现（每秒3或5张）。事件相关电位，记录了一个密集的电极阵列，表现出选择性歧视的情感唤起刺激，从情感内容。这种激活的主要来源是枕叶皮层，延伸到右顶叶皮层：这表明后视觉系统的处理焦点。情感歧视是独立的正式的图片属性（颜色，亮度，空间频率和复杂性）。这些数据支持一个非常短期的概念记忆存储的假设（M。C. Potter，1999）--这里显示的是对情感意义的短暂但可靠的评估。
The visual brain quickly sorted stimuli for emotional impact despite high-speed presentation (3 or 5 per s) in a sustained, serial torrent of 700 complex pictures. Event-related potentials, recorded with a dense electrode array, showed selective discrimination of emotionally arousing stimuli from less affective content. Primary sources of this activation were over the occipital cortices, extending to right parietal cortex: suggesting a processing focus in the posterior visual system. Emotion discrimination was independent of formal pictorial properties (color, brightness, spatial frequency, and com plexity). The data support the hypothesis of a very short-term conceptual memory store (M. C. Potter, 1999)-shown here to include a fleeting but reliable assessment of affective meaning.
