Acetylcholine (ACh) hyperpolarized the rat diaphragm muscle fibers by 4.5 +/- 0.8 mV (K0.5 = = 36 +/- 6 nmol/l). The AC-induced hyperpolarization was blocked by d-tubocurarine and ouabain in nanomolar concentrations. This effect of ACh was not observ

Within the last few years, the expression of voltage-dependent, TTX-sensitive Na+ channels has been demonstrated in several types of neuroglial cells such as astrocytes and Schwann cells. Recently, we reported the occurrence of such Na+ currents in r

Simultaneously recorded slow PIII (sPIII) and the late receptor potential of the frog isolated aspartate-treated retina were studied under different intensity and duration of light stimuli. The earlier suggested model of the sPIII generation in Müll

Similar downhill gradients of [K]0 were revealed in the aspartate--treated dark--adapted frog retina and in the eye cup without aspartate. [K]0 in the receptor layer is 8 X 10(-3) M, while in the proximal retina it is nearly 2.7 X 10(-3) M. Illuminat

The role of Ca++ in photoreception was studied by releasing these ions in rod cytoplasma from mitochondrias under 2,4 DNP/10(-4) M/action or blocking the transmembrane Ca++ transport by LaCl3 application (0.1; 0.5; 4 mM). The late receptor potential

In isolated frog retina after treatment with aspartate the photoinduced change of the extracellular potassium ions concentration [K+]0) was compared with slow PIII potential (sPIII). The time course of [K+]0 change in the outer nuclear layer was like
