Ionic Basis of the Action Potential
B. Role of axoplasm -There was a great debate about the nature of the action potential and the role of the axoplasm vs. the axonal membrane, lasting well into the first quarter of this century. Hermann (1872, 1905) was the first to recognize that the potential changes associated with an excited region of axon would send small currents (Strömchen) down the axoplasm, which would electrotonically,...
متن کاملThe Ionic Requirements for the Initiation of Action Potentials in Insect Muscle Fibers
Electrical properties of locust leg muscle fibers were studied by means of intracellular electrodes. In most fibers, a depolarizing current pulse initiated a local response. A delayed decrease in membrane resistance appeared with more than about 10 mv depolarization. In some fibers a regenerative response also was found. Membrane constants were measured, applying the short cable model. The valu...

Bacteriol. 82:909912. 1961.-Suspensions of Treponema pallidum, prepared by extracting the testes of syphilitic rabbits with normal rabbit serum or with a culture medium, were shaken with Amberlite IRC-50 resin in the sodium ion form. ...
متن کاملIonic gradients, membrane potential and ionic currents
The neuronal plasma membrane delimits the whole neuron, cell body, dendrites, dendritic spines, axon and axon terminals. It is a barrier between the intracellular and extracellular environments. The general structure of the neuronal plasma membrane is similar to that of other plasma membranes. It is made up of proteins inserted in a lipid bilayer, forming as a whole a ‘fl uid mosaic’ ( Figure 3...
متن کاملMass Action in Ionic Solutions.
The law of mass action describes reactants as simple ideal fluids of concentrations of uncharged noninteracting particles. Ionic solutions contain interacting charged particles and are not ideal. Interactions of reactants can then be mistaken for complexities in chemical reactions or enzymatic catalysts. The variational theory of complex fluids describes flowing mixtures like biological solutio...
