Today it seems self-evident that neurons make their electrical signals by opening gates of water-filled pores (ion channels) in the plasma membrane. But it was not always so. Remarkably ...

Ion channel proteins are found on all cell types and allow the passage of ions across cellular membranes. They are involved in a wide variety of biological processes and are implicated in many ...

They calculated the expected electrical current measurements until finally, they generated recordings that appeared to be ion channels, which convinced them that they were on the right track. Their ...

In plants, guard cells control the stomatal opening by expanding and contracting through ion flux. When a plant senses light, a signal is sent to the guard cell to increase its ion content, which ...

"There is an established method that can be used to measure whether an ion channel is open ... in diameter at the channel and recording changes in electrical current." The problem with this ...
