The fourth edition of this highly successful text has been extensively revised and restructured to take account of the many recent advances in the field. The classic observations of recent years can now be interpreted with the powerful new techniques of molecular biology. Consequently, there is much new material throughout the book, including many new illustrations and extensive references to recent work. The text's essential philosophy remains the same, however: it clearly explains fundamental concepts, and examines key experiments in detail. This thorough and clearly written textbook will be valuable for students of physiology, neuroscience, cell biology and biophysics.

Ion channels are crucial components of living cells. Situated in the cell membrane, they allow ions to pass from one side of the membrane to the other. This book provides an overview of ion channel study, including up-to-date coverage of the permeability and selectivity of channels, their gating and modulation, their response to drugs and toxins, and the human diseases that result from channel malfunction. Students of molecular biology, biochemistry, physiology, and neurobiology will benefit from this modern, concise text.
