Comparison of excitatory currents activated by different transmitters on crustacean muscle. I. Acetylcholine-activated channels
The properties of acetylcholine-activated excitatory currents on the gm1 muscle of three marine decapod crustaceans, the spiny lobsters Panulirus argus and interruptus, and the crab Cancer borealis, were examined using either noise analysis, analysis of synaptic current decays, or analysis of the voltage dependence of ionophoretically activated cholinergic conductance increases. The apparent me...
متن کاملComparison of excitatory currents activated by different transmitters on crustacean muscle. II. Glutamate-activated currents and comparison with acetylcholine currents present on the same muscle
The properties of glutamate-activated excitatory currents on the gm6 muscle from the foregut of the spiny lobsters Panulirus argus and interruptus and the crab Cancer borealis were examined using either noise analysis, analysis of synaptic current decays, or slow iontophoretic currents. The properties of acetylcholine currents activated in nonjunctional regions of the gm6 muscle were also exami...
متن کاملMechanisms of noncompetitive inhibition of acetylcholine-induced single- channel currents
The functional mechanisms of noncompetitive blockade of the nicotinic acetylcholine receptor from the BC3H-1 cell line were examined using single-channel currents recorded from cell-attached patches. Channel open times were distributed as sums of two exponentials and the closed times as sums of at least four exponentials. The single-channel currents of the receptor were analyzed in terms of act...

15 صفحه اولNerve terminal currents induced by autoreception of acetylcholine release.
The activation of autoreceptors is known to be important in the modulation of presynaptic transmitter secretion in peripheral and central neurons. Using whole-cell recordings made from the free growth cone of myocyte-contact motoneurons of Xenopus cell cultures, we have observed spontaneous nerve terminal currents (NTCs). These spontaneous NTCs are blocked by d-tubocurarine (d-TC) and alpha-bun...
