摘要：

A new liquid membrane microelectrode was developed that was easily fabricated and could measure fast Na+ transients in the presence of K+ interference. It responded to a sudden change in Na+ activity within 1 s. The electrode was used to provide the 1st direct evidence of large Na+ transients in the extracellular space of the brain of the catfish.
