Interactions between simultaneously recorded pairs of neurons in the magnocellular and gigantocellular fields of the reticular formation were studied in unanesthetized, unrestrained cats. Each cell pair was recorded during both waking and REM sleep. Dependencies in discharge between spike trains were observed visually and with cross-correlation analyses. These dependencies were present at both short-latency and long-latency intervals. Dependencies were observed with equal frequency in waking and REM sleep. Short duration (1 to 3 ms) interactions were found in 40% of significant cross correlations and were most common in adjacent cells with related behavioral correlates. Patterns of discharge in REM sleep were similar to those in waking. These results suggest that there is common synaptic input to a large proportion of adjacent reticular cell pairs during both waking and REM sleep. Synchronized firing in local cell clusters may be a way in which reticular formation contributions to complex motor behavior are synthesized.
在未麻醉、未束缚的猫身上，研究了网状结构的大细胞和巨细胞区域中同时记录的神经元对之间的相互作用。在清醒和快速眼动睡眠期间都记录了每对细胞。通过视觉观察和互相关分析观察了尖峰序列之间放电的相关性。这些相关性在短潜伏期和长潜伏期间隔都存在。在清醒和快速眼动睡眠中观察到相关性的频率相同。在40%的显著互相关中发现了持续时间短（1至3毫秒）的相互作用，并且在具有相关行为关联的相邻细胞中最为常见。快速眼动睡眠中的放电模式与清醒时相似。这些结果表明，在清醒和快速眼动睡眠期间，很大一部分相邻的网状细胞对都有共同的突触输入。局部细胞簇中的同步放电可能是网状结构对复杂运动行为做出贡献的一种合成方式。
