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 ...

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

Due to their simple body structure with a limited number of cell types, freshwater polyps (Hydra) can be used to study many fundamental processes of life. In recent years, Hydra has also experienced a ...

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 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 years, ...

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 ...

University of Alabama at Birmingham researchers, for the first time ever, have achieved patch-clamp studies of an elusive part of mammalian myelinated nerves called the Nodes of Ranvier. At the nodes, ...

THE theory of transmission of nervous impulses to the voluntary muscles postulates the presence of a high concentration of choline esterase in nerve endings or their neighbourhood 1. We have ...

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

One of the greatest, relatively underappreciated, discoveries in all of science was the discovery of the nerve impulse in the 1930s by the British Lord Adrian. Adrian did win a Nobel Prize for his ...
