Certain cells, commonly called excitable cells, are unique because of their ability to generate electrical signals. Although several types of excitable cells exist — including neurons, muscle cells, ...

Ion channels generate electrical impulses produced by living cells. Synthetic ion channels could serve as tools for ...

Ion channels are pores in the membrane of cells or cell organelles. They allow positively or negatively charged particles, so-called ions, to be transported across the membrane. Biochemists at ...

Ion selectivity is an important property of cell membrane ion channels. For example, potassium ion channels are more permeable to potassium ions than to sodium ions. The mechanism underlying the ready ...

New research reveals how tiny electrical gates in the brain, known as NMDA receptors, control learning, memory, and neuron ...

In studying how neurotransmitters travel between cells, Cornell researchers have discovered that an electrical current thought to be present during that process does not, in fact, exist. The ...

Researchers at Göttingen Campus, Germany, have succeeded for the first time in examining the tiny synapses in the inner ...

Ion channels are transmembrane proteins specifically involved with the transport of inorganic ions like Na+, K+, Ca2+, or Cl-. Ion channels are “gated”, i.e. they open in response to a specific ...

Fluoride protects our teeth against cavity-causing bacteria by making our teeth stronger. But what if we could find a way to trap fluoride ions (the negatively charged form of the chemical element ...
