我们曾经报导过,微量的海人酸注入大鼠的海马腹前部,七天后几乎完全阻断大鼠避暗行为的学习和记忆,组织学检查表明几乎损毁整个海马的CA_3、CA_4锥体细胞,初步确定这些锥体细胞与这一模式的学习和记忆直接相关。本实验在观察到海人酸注入 We have previously reported that a small amount of kainate was injected into the anterior abdominal portion of the hippocampus of rats, almost completely blocking the learning and memory of dark-avoidance behavior in rats seven days later. Histological examination showed that CA_3 and CA_4 pyramidal cells , Initially determined that these pyramidal cells are directly related to this pattern of learning and memory. The experiment was observed kainic acid injection
