To elucidate the nature of negative and positive phases of background delta-waves (BDW), their interaction with evoked potentials was studied in the rabbit visual cortex. BDW appeared after injection of drugs synchronizing ECoG: amyzyl, aminozin, barbiturates, and during asphyxia. The flashes evoked slow positive responses lasting about 0.5 to 1.0 s. These responses blocked the negative BDW. The results of the study and published data suggest that background delta-activity consists of segments which reflect the desynchronized state and correspond to positive BDW, and of segments which reflect active inhibition in the cerebral cortex and correspond to negative BDW.
为了阐明背景δ波（BDW）正负相的本质，我们在兔视觉皮层中研究了它们与诱发电位的相互作用。在注射使脑电图同步的药物（阿米妥、氨苯异辛、巴比妥类）后以及窒息期间出现了BDW。闪光诱发了持续约0.5至1.0秒的缓慢正反应。这些反应阻断了负性BDW。该研究结果和已发表的数据表明，背景δ活动由反映去同步化状态并对应于正性BDW的片段以及反映大脑皮层主动抑制并对应于负性BDW的片段组成。
