Hippocampal and cortical activity were studied during sexual behavior in the female rat. Hippocampal theta appeared during her soliciting behavior. High-frequency theta accompanying the male's pursuit slowed when the male mounted the female and then increased in frequency during the brief continuation of lordosis following mounts without vaginal penetration. During prolonged lordosis after intromissions and ejaculations, slow theta continued. No changes in cortical frequencies were observed during mounts, intromissions, or ejaculations. During immobility (standing, sitting, and lying down) hippocampal activity became slow and irregular. High-amplitude hippocampal and, eventually, cortical spindles developed during immobility as sexual exhaustion was approached. Immobility and its accompanying electroencephalographic spindling are interpreted as indicative of a sexual satiety or inhibitory process.
在雌性大鼠性行为期间，对其海马体和皮质活动进行了研究。在其求偶行为期间出现了海马体θ波。当雄性追逐时，伴随的高频θ波在雄性骑跨雌性时变慢，然后在骑跨后没有阴道插入的短暂脊柱前凸持续期间频率增加。在插入和射精后的长时间脊柱前凸期间，慢θ波持续存在。在骑跨、插入或射精期间，未观察到皮质频率的变化。在静止状态（站立、坐着和躺下）时，海马体活动变得缓慢且不规则。随着性疲劳的临近，在静止状态下会出现高振幅海马体纺锤波，最终出现皮质纺锤波。静止状态及其伴随的脑电图纺锤波被解释为性满足或抑制过程的指标。
