从体外分离的小鼠体感皮层神经元进行细胞内记录。观察到两种生理学上不同的锥体细胞：规则尖峰细胞占多数，并产生单尖峰的适应列车;爆裂细胞产生2-5个动作电位的簇，簇被长时间的后超极化分开。小鼠新皮层的爆裂细胞在持续电流脉冲期间产生重复爆裂是不寻常的，并且被定位于横跨层V和VI的层流区。
Intracellular recordings were made from neurons of the mouse somatosensory cortex isolated in vitro. Two physiologically distinct classes of pyramidal cells were observed: regular-spiking cells were the majority, and generated accomodating trains of single spikes; bursting cells generated clusters of 2-5 action potentials, and clusters were separated by prolonged afterhyperpolarizations. The bursting cells of the mouse neocortex were unusual in producing repetitive bursting during sustained current pulses, and in being localized to a laminar zone straddling layers V and VI.
