The brain is constantly mapping the external world like a GPS, even when we don't know about it. This activity comes in the form of tiny electrical signals sent between neurons—specialized cells that ...

Medically reviewed by Huma Sheikh, MD Neurons are cells in the body that are responsible for transmitting electrical signals through the nervous system. Different types of neurons affect the ...

Neurons are responsible for carrying information throughout the human body. Using electrical and chemical signals, they help coordinate all of the necessary functions of life. In short, our ...

Neurons are composed of a cell body containing the nucleus, dendrites that receive chemical, electrical, or other signals via receptors or through gap junctions (direct connections between two ...

Epithelial conversation An epithelial cell-coated microelectrode array with 60 precisely placed electrodes detects the minute electric signals generated when the cells are injured. (Courtesy: UMass ...

Although neurons are considered the basic units of the brain and nervous system, they do not do all the work. Glia are a non-neuronal category of cells that do not transmit electrical signals but ...

A nimal bodies are crackling with electrical signals. Even before development is complete, electric fields guide the movement and arrangement of embryonic cells. 1 In adults, neurons communicate with ...

Neurons talk to one another using electricity. If you could hear these impulses, they might sound like constant, rapid-fire chatter all over the nervous system. Heart muscle cells do something similar ...

Heart muscle cells do something similar, issuing electrical “heave-ho” signals that make the organ beat. Skin and other epithelial cells, however, were thought to be silent; they form barrier ...

Those electrical signals produce patterns of activity some researchers say resembles neurons, which have served broadly as inspiration for advancements in modern machine learning and robotics.
