1·METHODS: Extracellular population spikes of the pyramidal cell layer in the hippocampal CA1 region were recorded in vitro.

方法：细胞外记录离体海马脑片CA1区锥体细胞层群体峰电位。

2·Methods With pyramidal cell tissues stained in silver nitrate, brain pyramidal cells were displayed by paraffin section method.

方法应用大脑锥体细胞组织块浸银染色，石蜡包埋切片显微镜观察大脑锥体细胞。

3·The moderate density IL 2R ir neurons were distributed in the pyramidal cell layer of the hippocampal gyrus, the granular cell layer and polymorphous cell layer of dentate gyrus.

中等密度的IL-2R免疫反应神经元分布在海马锥体细胞层和齿状回颗粒细胞层和多形细胞层。

4·Beneath the dorsal wall of it, a neuroglia cell cluster in a pyramidal form was often seen, extending dorsally along the median line.

在其背侧壁的室管膜下，常可见一锥形神经胶质细胞群，在背侧正中线上伸展。
