Dopamine—a neurotransmitter responsible for influencing motivation, pleasure, mood and learning in the brain—has experienced ...

New insights into the opposing actions of serotonin-producing nerve fibers in mice could lead to drugs for treating addiction and major depression. Scientists in Japan have identified a nerve pathway ...

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, ...

Note: Some students might have trouble discussing this topic because they may have a family member with Alzheimer's disease. Model a nerve cell. Explain to students that the nervous system functions ...

(Philadelphia, PA) – Researchers at the University of Pennsylvania School of Medicine have discovered the mechanism that facilitates how two ion channels collaborate in the control of electrical ...

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, ...

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, ...

Schwann cells form a protective sheath around nerve fibers and ensure that nerve impulses are transmitted rapidly. If these cells are missing or damaged, severe neurological diseases may occur as a ...

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 ...

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 ...
