跨大皮层区域传播的自发活动波可能在感觉处理和电路细化中发挥重要作用。然而,这些波是否反过来由感官体验塑造仍不清楚。在这里,我们报告视觉诱发的皮层活动在随后的自发波中产生回响。大鼠视觉皮层的电压敏感染料成像表明,在重复呈现给定的视觉刺激后,类似于诱发反应的时空活动模式在自发波中更频繁地出现。这种效应特定于重复刺激引起的反应模式,并且在没有进一步视觉刺激的情况下持续几分钟。这种波介导的混响可能有助于短期记忆,并有助于将近期感官体验的短暂影响巩固为持久的皮质变化。
Spontaneous waves of activity propagating across large cortical areas may play important roles in sensory processing and circuit refinement. However, whether these waves are in turn shaped by sensory experience remains unclear. Here we report that visually evoked cortical activity reverberates in subsequent spontaneous waves. Voltage-sensitive dye imaging in rat visual cortex showed that following repetitive presentation of a given visual stimulus, spatiotemporal activity patterns resembling the evoked response appear more frequently in the spontaneous waves. This effect is specific to the response pattern evoked by the repeated stimulus, and it persists for several minutes without further visual stimulation. Such wave-mediated reverberation could contribute to short-term memory and help to consolidate the transient effects of recent sensory experience into long-lasting cortical modifications.
