The original nerve impulse findings were that the rate of impulse firing governed the impact on neuronal targets, whether they be muscle or other neurons. Various labs, including my own, in the 1980s, ...

Researchers have discovered a new mechanism by which substances can open a certain type of ion channel and in this way regulate nerve impulses. The study identifies a large group of substances that ...

As you read these words, billions upon billions of electrical impulses are flying through your brain. In a complex symphony of activity all those impulses are somehow encoding your thoughts, feelings, ...

Researchers have achieved patch-clamp studies of an elusive part of mammalian myelinated nerves called the Nodes of Ranvier. At the nodes, they found unexpected potassium channels that give the ...

The “wires” that carry electrical signals among nerve cells in the brain can influence the threshold at which the cells will send those signals, research on mouse-brain tissue shows. The finding ...

ETH researchers have developed a new generation of microelectrode- array chips for measuring nerve impulses, enabling studies of how thousands of nerve cells interact with each other. For over 15 ...

AT the Friday evening discourse held at the Royal Institution on February 10, Prof. A. V. Hill discussed the physical nature of the nerve impulse. The properties of the nervous system are based upon a ...

For over 15 years, ETH Professor Andreas Hierlemann and his group have been developing microelectrode-array chips that can be used to precisely excite nerve cells in cell cultures and to measure ...

(1) A nerve impulse arrives. (2) This causes calcium ion channels to open, resulting in an influx of calcium ions in the terminal. (3) This causes synaptic vesicles to fuse with the terminal membrane, ...

Jackson Ryan was CNET's science editor, and a multiple award-winning one at that. Earlier, he'd been a scientist, but he realized he wasn't very happy sitting at a lab bench all day. Science writing, ...
