Potentials Associated with the Blood- Brain Barrier of an Insect: Recordings from Identified Neuroglia
The blood-brain barrier of the insect nervous system is thought to be formed by the neuroglia. It is associated with a positive interstitial potential relative to the bathing medium ('sheath' potential), and with positive changes in potential that can be induced by raising the potassium level in the bathing medium. In central nervous connectives of the cockroach, Periplaneta americana, these po...
متن کاملThe Generation of Bioelectric Potentials
EVER since Matteucci and DuBois Reymond established the fact that muscle and nerve activity is associated with bioelectric, potentials, it has been safe to assume that contraction of the heart must also have an electric correlate. Although Koelliker and Johannes Mueller actually were the first to succeed in demonstrating such electric activity, it was only when Einthoven, using a sufficiently s...

متن کاملCalculations of Bioelectric Potentials
Interest in the study of Halicystis and of Valonia has been stimulated by discoveries of marked contrasts and striking similarities existing side by side. This is illustrated by new experiments with the alkali metals and alkaline earths. In Halicystis the apparent mobilities of K(+), Rb(+), Cs(+), and Li(+) (calculated by means of Henderson's equation from changes in P.D. produced by replacing ...
متن کاملBioelectric Potentials in Valonia
In their influence on the P.D. across the protoplasm of Valonia macrophysa, Kütz., Li(+) and Cs(+) resemble Na(+), while Rb(+) and NH(4) (+) resemble K(+). The apparent mobilities of the ions in the external surface layer of Valonia protoplasm increase in the order: Cs(+), Na(+), Li(+) < Cl(-) < Rb(+) < K(+) < NH(4) (+).
