Dielectric Relaxation in Lipid Bilayer Membranes

  • S. Takashima
  • H. P. Schwan


Takashima, Schwan and Tasaki(l) observed that the membrane capacitance of squid axon undergoes a dielectric relaxation in the proximity of lOKHz. They found, after careful analyses of data(vide infra) that the widely accepted membrane capacity luF/cm2 of nerve axon membrane(2) decreased to approximately 0.6 uF/cm2 between 2 and 50KHz. The origin of the frequency dependent membrane capacitance is still unknown and the present research is a further attempt to identify the component which undergoes the dispersion in the low frequency region.
