A thickness of about 100 angstroms of the cell membrane of an isolated single freeze-dried neuron of the snail can be etched off with an ion shower milling machine. The calcium content of the cell membrane area was more than one-fifth of the whole cell. The calcium content of the cell membrane area increased during pentylenetetrazole-induced bursting activity.
用离子束溅射仪可以蚀刻掉分离出的单个蜗牛冷冻干燥神经元约100埃厚的细胞膜。细胞膜区域的钙含量超过整个细胞的五分之一。在戊四氮诱发的爆发活动期间,细胞膜区域的钙含量增加。
