Ion channels are one of the two classes of ionophoric proteins, the other being ion transporters.

Some channels are fairly selective, others allow several types of ions to move across the membrane. See Acetylcholine receptor for an example. --JWSchmidt 16:12, 7 August 2006 (UTC)

These membranes are flat sheets that form a continuous barrier around all cells. The cell membranes of almost all organisms and many viruses are made of a lipid bilayer, as are the nuclear membrane surrounding the cell nucleus, and other… In 1984, Hille started a new direction of studying the modulation of ion channels by G protein–coupled receptors. He distinguished two new signaling pathways for excitable cells. Because the currents applied to the cell must be equal to (and opposite in charge to) the current going across the cell membrane at the set voltage, the recorded currents indicate how the cell reacts to changes in membrane potential. Factors that may induce such changes include temperature, pH, voltage, light in chromophores, ion concentration, phosphorylation, or the binding of a ligand.Transitions between these states occur on a variety of length scales (tenths of Å… Our objective was to find voltage-gated ion-channel genes in basal animals and their close unicellular relatives, determine whether the genes are expressed in a few key species, and analyze the evolutionary history of the genes for Nav and… Ion Channels in Cell Membranes: Phylogenetic and Developmental Approaches (1983~. In 1983 a symposium volume was pub- lishec! in his honor (The Physiology of Excitable Cells, eclitec!

Nerve conduction in myelinated axons is referred to as saltatory conduction (from the Latin saltare "to hop or to leap") due to the manner in which the action potential seems to "jump" from one node to the next along the axon.

Significantly, ω-CgTx is capable of long term binding to and inhibition of voltage-dependent calcium channels located in the membranes of neurons but not those of muscle cells. The Hille equation relates the maximum ionic conductance of an ion channel to its length and radius (or diameter), with the commonly used version implicitly takes into account a hemispherical cap.

Inhibitory feedback underlies the formation of center-surround antagonistic receptive fields, which support edge detection, create color opponency, and enhance contrast (Wu, 1992; Burkhardt, 1993; Twig et al., 2003).

Previous studies using ion-selective fluorescent probes suggested a role of voltage-sensitive Ca2+ channels in acrosome reactions.
