Published: 15 May 2004
...Mark R. Rheault; Michael J. O'Donnell SUMMARY Transport of the prototypical organic cation tetraethylammonium (TEA) by the Malpighian tubules, ureters and gut of Drosophila melanogaster was studied using two novel electrophysiological techniques. Both techniques exploited the high selectivity...

... Mn 2+ or 24 μmol l −1 nimodipine. Tetraethylammonium ions at 1–5 mmol l −1 also blocked propagation without prolonging the action potential. Impulse conduction in the sponge is discussed in relation to excitability and conduction in the protozoa and in plants and to non-nervous conduction in more...

... and was sensitive to 5 mmol l −1 tetraethylammonium; a rapidly inactivating, 4-aminopyridine (4-AP)-sensitive, A-type K + current and a Ca 2+ -sensitive K + current that was blocked by 200 nmol l −1 charybdotoxin and 10 mmol l −1 Cd 2+ but was insensitive to apamin. The proportion of each current type varied from...

...M. J. O’Donnell ABSTRACT Depolarization of Rhodnius oocytes evokes action potentials (APs) whose rising phase is calcium-dependent. The ionic basis for the repolarizing (i.e. falling) phase of the AP was examined. Addition of potassium channel blockers (tetraethylammonium, tetrabutylammonium, 4...
