According to the traditional theory of nerves, two nerve impulses sent from opposite ends of a nerve annihilate when they collide. New research now shows that two colliding nerve impulses simply pass ...

Scientists have solved a longstanding mystery of the central nervous system, showing how a key protein gets to the right spot to launch electrical impulses that enable communication of nerve signals ...

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 ...

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, ...

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 ...

Every muscular function of the human body is triggered by a small electrical current transmitted to the muscles through the nerves. Doctors have long assumed that a chemical reaction at the synapses ...

The myelin sheath is a protective covering that surrounds fibers called axons, which are the long thin projections that extend from the main body of a nerve cell or neuron. This sheath is composed of ...

IN 1921 it was proved for the first time that the modifications of the heart's function, caused by stimulation of its nerves, are due to substances liberated by the stimulation, called transmitters: ...

At first glance, nerve cells would appear to be energy hogs. The brain accounts for only about two percent of a human's body mass, but burns through 20 percent of its energy budget. But transmitting ...

Your muscles move when nerve signals from the brain tell them to get to work. Electromyography (EMG), a diagnostic test, measures how well your muscles respond to those signals. Movement is a complex ...
