Abstract. Ionic channels, the integral membrane proteins responsible for the brain's electrical activity, have long been studied with standard electrophysiological and biochemical methods. Recently, however, newly developed electrical and molecular biological methods have been brought to bear on long-standing questions in neurobiology.

Ion channel-mediated ionic currents can be readily recorded in a cell-attached mode or after the patch has been excised from the rest of the cell membrane (excised patch mode). Mechanical activation of ion channels can be controlled by applying subsequent pulses of positive or negative pressure in the pipette.

Mechanosensitive ion channels are cellular mechanosensors essential for ultra-rapid conversion of mechanical stimuli into biologically relevant signals. Cox et al. revisit the biophysical principles that underlie the innate force-sensing ability of these mechanoreceptors and conclude that the force-from-lipids principle is the most evolutionarily conserved paradigm for ion channel.

Roadmap on emerging concepts in the physical biology of bacterial biofilms: from surface sensing to community formation. One of the most common questions from incoming graduate students is whether they have to master biology before doing biophysics. The answer is not a simple one. Adapting an idea from Karl Kraus may begin to answer this.

About this book. Ion channels are biological nanotubes that are formed by membrane proteins. Because ion channels regulate all electrical activities in living cells, understanding their mechanisms at a molecular level is a fundamental problem in biology. This book deals with recent breakthroughs in ion-channel research that have been brought.

Mechanisms and physiological implications of cooperative gating of clustered ion channels

the role of ion channels in the modeling of cancer biophysics has recently been noted 10,11 and ion channel blockers relevant to the effects shown in Fig. 6 are available (see e.g. refs 15 and 45.

New study challenges 'established' mechanism about selectivity of cellular ion channels

Introduction. In the late 1940s, Hodgkin and Huxley were the first to highlight the importance of ionic movements in cell excitability. They showed that the process was mediated by dedicated structures now known as ion channels (Hodgkin and Huxley, 1952).Thirty-two years later, the first voltage sensitive ion channel was cloned (Noda et al., 1984).To date, at least 140 similar structures have.
