Abstract The rat α9 nicotinic acetylcholine receptor (nAChR) was expressed in Xenopus laevis oocytes and tested for its… Expand Nicotinic acetylcholine receptors present on cultured hippocampal neurons from fetal rats were characterized by means of whole… Expand The fine structure of ion‐channel activations by junctional nicotinic receptors in adult frog muscle fibres has been investigated… Expand We studied activation of the nicotinic acetylcholine (ACh) receptor on cells of a mouse clonal muscle cell line (BC3H1). We… Expand Acetylcholine-like drugs cause ion channels in the skeletal muscle endplate to open briefly1, producing, at random intervals… Expand 1. Single channel currents through acetylcholine receptor channels (ACh channels) were recorded at chronically denervated frog… Expand 1. Frog neuromuscular junctions were viewed with Nomarski optics and voltage clamped. Agonist was applied ionophoretically and… Expand 1. In the absence of procaine the end‐plate conductance evoked by suberyldicholine increases exponentially to a new level… Expand Membrane currents from voltage-clamped frog muscle fibers were recorded during iontophoretic application of steady doses of… Expand 1. End‐plate depolarization and associated ‘membrane noise’ due to decamethonium, acetylthiocholine and suberyldicholine have… Expand
