The relationship between dreaming and rapid eye movements (REM) during REM sleep is still controversial. This study records the brain potentials time-locked to the onset and offset of REM in 11 healthy young volunteers. Before the onset of REM, no presaccadic readiness potential was found. Conversely, two positive potentials (P1 and P2) appeared following the offset of REM. The latter potentials were dominant in the parieto-occipital area. These findings suggest that REM is initiated without preparation but elicits some information-processing activities that were speculated to occur in the cortical visual area. The data support the activation-synthesis or association hypothesis of dreaming rather than the scanning hypothesis.
快速眼动睡眠期间做梦与快速眼动（REM）之间的关系仍存在争议。本研究记录了11名健康年轻志愿者中与快速眼动开始和结束时间锁定的脑电位。在快速眼动开始前，未发现眼跳前准备电位。相反，在快速眼动结束后出现了两个正电位（P1和P2）。后一种电位在顶枕区占主导。这些发现表明，快速眼动的启动没有准备，但会引发一些推测发生在皮质视觉区域的信息处理活动。这些数据支持了梦的激活-整合或联想假说，而非扫描假说。
