摘要: Ionic changes in limited intra- and extracellular spaces are the consequence of generation every biopotential. A wide range techniques has been used recent years to show that normal neuronal activity causes K+ accumulate narrow clefts separating cellular elements. However, it was not until — selective microelectrodes with liquid ion exchanger Corning code 477317 had developed by J.L. Walker 1971 possible measure dynamic vicinity active neurones fibres. This development brought a new surge interest functional significance transient accumulation nervous system. The two main questions at time were: 1) What [K+]e occur during activity? 2) How might these affect functioning system?
