Cerebral blood delivery depends on mechanisms such as electrical signaling, which propagates through capillary networks to upstream arterioles to deliver blood, and calcium signaling, which fine-tunes ...

What happens inside the carnivorous plant Venus Flytrap when it catches an insect? New technology has led to discoveries about the electrical signalling that causes the trap to snap shut.

Researchers at the University of Warwick have found bacteria can be detected in minutes by zapping them with electricity. Scientists at the university in the United Kingdom discovered healthy bacteria ...

A new study found that deep sleep weakens breathing brain timing in movement circuits and changes internal brain ...

Both image photodetector arrays and retinas are pixelated sensors that dynamically extract various features from the visual scene—e.g., color, brightness, and contrast—before transmitting electrical ...

Electrical signals commonly occur in plants in response to various environmental changes and have a dominant function in plant acclimation. Recently, a research team from Zhejiang University in China ...

Researchers at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) and Uniklinikum Erlangen have succeeded in preserving brain tissue through extreme deep freezing. After thawing, the neurons ...

Every time we feel a gentle tap on the skin, specialized nerve cells convert that physical force into an electrical signal ...
