The Roles of Membrane in Electrical Systems of Lives

Phospholipid bilayer membrane is the key element of living organisms.This talk discusses several additional roles that membrane plays in electrical systems of a live creature.Electric eels demonstrate typically the capacitance-like electrical energy storage mechanism.An electric eel contains lots of flat cells which store a small amount of electrostatic energy maintained by the transmembrane difference in ion concentration.When discharging,the cells simultaneously release their stored energy,leading to a high voltage.The transmembrane difference in ion concentration powers the generation of a transient ion current when ion channels are triggered open.And such a transient electrical current generates an solitonlike electromagnetic wave pulse.We have also recognized that such an electromagnetic pulse could transmit efficiently along the membrane itself.When the membrane(or myelin sheath) is sandwiched between ionic fluids at its both sides,it naturally forms a unique bio-material electromagnetic waveguide,showi...Phospholipid bilayer membrane is the key element of living organisms.This talk discusses several additional roles that membrane plays in electrical systems of a live creature.Electric eels demonstrate typically the capacitance-like electrical energy storage mechanism.An electric eel contains lots of flat cells which store a small amount of electrostatic energy maintained by the transmembrane difference in ion concentration.When discharging,the cells simultaneously release their stored energy,leading to a h国家外国专家局国外人才信息研究中心、重庆市人民政府会展办公室、重庆市经济与信息化委员会、重庆市科学技术委员会、重庆市人力资源和社会保障局
