On the Reversible Abrupt Structural Changes in Nerve Fibers Underlying Their Excitation and Conduction Processes
The cortical gel layer of nerve fibers has the properties of a cationexchanger. Hence, this layer can, and actually does, undergo a reversible abrupt structural change when monovalent cations (e.g. Na+) are substituted for the divalent counter-ions (e.g. Ca2+). This structural change brings about a sudden rise in the water content of the layer which in turn produces a large enhancement of catio...

متن کاملRepetitive abrupt structural changes in polyanionic gels: a comparison with analogous processes in nerve fibers.
Repetitive abrupt structural changes can be produced in a small piece of cross-linked polyacrylate hydrogel by exchanging the divalent counter-ions in the superficial gel layer to monovalent cations. The temporal variations of the hydrostatic pressure, electric impedance and potential associated with these structural changes frequently show striking resemblance to those encountered during repet...
متن کاملChanges in fluorescence, turbidity, and birefringence associated with nerve excitation.
The objective of this paper is to offer experimental evidence which shows that the process of excitation in the nerve is accompanied by a transient change in optical properties of the nervous tissue. The optical properties examined include fluorescence, turbidity, and birefringence. Changes in fluorescence were examined after nervous tissues were stained with the dye 8-anilinonaphthalene-1-sulf...
متن کاملBirefringence Associated with Nerve Excitation
The objective of this paper is to offer experimental evidence which shows that the process of excitation in the nerve is accompanied by a transient change in optical properties of the nervous tissue. The optical properties examined in clude fluorescence, turbidity, and birefringence. Changes in fluorescence were examined after nervous tissues were stained with the dye 8-anilinonaphthalene-1-su...
