Extracellular recording of neuronal activity in anterior and posterior cingulate cortex was performed in unanaesthetized rabbits during electrical stimulation of the hippocampus and associative areas of anterior and posterior neocortex. Stimulation of the hippocampus was significantly more effective for posterior cingulate neurons (60% of reactive units) than for the anterior ones (18%). Most of reactive neurons in posterior cingulate cortex responded by time-locked effects; in anterior cingulate cortex such responses were rare. The latencies of the posterior cingular neuronal responses constituted two separate groups with the mean values 12.3 +/- 6.5 ms and 50.2 +/- 10.0 ms. Various forms of the activity suppression were also observed during hippocampal stimulation. Stimulation of posterior neocortex was almost equally effective for both areas of cingulate cortex: in more than a third of the units tested it evoked initial discharge followed by suppression of activity. Stimulation of anterior neocortex evoked such responses only in a limited proportion of anterior cingulate cortex neurons. The facts are discussed in the light of recent morphological data on connections between the investigated structures.
在未麻醉的兔子身上，于海马体以及前、后新皮质联合区域进行电刺激期间，对前扣带回皮质和后扣带回皮质的神经元活动进行了细胞外记录。海马体刺激对后扣带回神经元（60%的反应性单位）的效果明显比对前扣带回神经元（18%）更显著。后扣带回皮质中的大多数反应性神经元通过时间锁定效应做出反应；在前扣带回皮质中，这种反应很少见。后扣带回神经元反应的潜伏期分为两个独立的组，平均值分别为12.3±6.5毫秒和50.2±10.0毫秒。在海马体刺激期间还观察到了各种形式的活动抑制。后新皮质刺激对扣带回皮质的两个区域几乎同样有效：在超过三分之一的测试单位中，它引发了初始放电，随后是活动抑制。前新皮质刺激仅在前扣带回皮质神经元的有限比例中引发这种反应。根据最近关于所研究结构之间连接的形态学数据对这些事实进行了讨论。
