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 ...

Electrical impulses applied to a particular branch of the vagus nerve could be used in the future to reduce complications of arterial hypertension. These are the results of a research conducted, on ...

The fastest nerve fibers in the human body relay signals at speeds approaching 250 miles per hour, a rate that still leaves ...

Neuronal electrical activity correlates in a systematic way with these state changes. The most conspicuous of these activity measures exist in terms of nerve impulse firing and the extracellular ionic ...

An animal's brain consists of two different types of cell: neurons, which process and transmit information, and glial cells, which support the neurons in a variety of ways. In 1871, the French ...

Mechanoreceptors in human skin can sense the delicate weight of a butterfly, feel the heat of a nearby flame or a cool drink, understand whether a hand is raised in a fist or a peace sign, and count ...

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 intimate nature of the nervous impulse has long been a subject for speculation by physiologists and psychologists. Simple models to explain the mode of transmission of an impulse along a nerve, ...

The fastest electrical signals in the human body can travel at up to 120 meters per second, roughly 268 miles per hour, along ...
